This paves the way for a variety of more interesting interactions
between drivers and the stack which are currently not possible
(e.g. checksum offload, #18744). The main advantage for the moment
is that we will save a memcpy of the buffer on each send/receive.
Adapt the virtio_net driver so that at least one driver is using
the new interface. Network still seems to work OK with it.

Every time a page is mapped into an area on fault, we have to
allocate a mapping object for it. While the object_cache
does have per-CPU depots, these depots only store a limited
number of items, and once they run out the object_cache's lock
must be acquired.
So, to reduce lock contention on SMP systems, create a number
of object caches corresponding to the nearest power of 2
that is equal or smaller than the count of CPUs. (We already
allocate dozens of object caches for the block allocator
no matter how many CPUs there are, so a few more depending
on CPU count shouldn't impact memory use too much. Besides,
the object_caches are wired into the low_resource system.)
This significantly reduces lock contention on SMP systems.
Same benchmark setup as yesterday (compile mime_db and relink
HaikuDepot, VMware, -j4), before:
real 0m16.981s
user 0m14.357s
sys 0m6.060s
after:
real 0m14.522s
user 0m14.194s
sys 0m4.337s
And the page_mappings object_cache locks went from having 200,000+ waits
and ~14 seconds waiting time (across all threads) down to ~900 (yes,
that's not a typo) and ~0.05s wait time (though these numbers were captured
in conjunction with the following commit.)
This is an alternative to DT_HASH (SystemV/SVR4 hash tables.) Notably,
it uses a Bloom filter to allow an entire image to be skipped
at once rather than searching the actual symbol hash.
We don't currently build anything with DT_GNU_HASH support.
You can test this by adding -Wl,--hash-style=both to HAIKU_LINKFLAGS.
(It seems to increase image sizes by not too much: libroot goes
from 1347139 to 1367691 bytes (20.55 KB) in my build.)

This only happens on team exit and exec. In the exec case, we can
just document that this implies all images are removed from the team.
It appears all consumers of the debugger API handle this correctly as-is.
Instead of taking the sample inside the timer callback
or the flush callback depending, always take it in the timer
callback, for consistency's sake. This should always work
because we try to flush the buffer when it's only 70% full;
in testing I can't recall seeing any dropped ticks.
Also add a flush call in the post_syscall hook, in case
we hit the flush threshhold while profiling in the kernel
and couldn't trigger the flush then.
Seems to significantly reduce "missed" ticks overall,
but there are still wildly inconsistent results and
lots of missing time.

Without this, a query term that does have an index but for which
the pattern starts with a wildcard (e.g. "*term*") is treated as having
a score of 0. That means that it is then dependent on the query order
as to whether or not the equation will run at all, since if all the terms
have a score of 0 but one has an index, placing that term first
will make the query run while any other would not.
Fixes #18672.
If we have a matching operator, we will replace the current item
with a new item, and we may need to process it again. For example,
in cases like "A||B||C", the first pass will turn this into "(A||B)||C",

Adds a `signal` field to the `team_deleted` event. Since killing
signals like `SIGKILL` and `SIGKILLTHR` do not generate a
`signal_received` event, debuggers would only see a `team_deleted`
message with the `status` field set to 0. This makes debuggers like
GDB think that the debuggee has exited with a status code of 0.
To correctly report these signals, when a killing signal is sent
to a team, this signal is relayed to the main thread instead of
defaulting to just a `SIGKILLTHR` for both cases.

* Rewrote the main "l2cap.h" header representing protocol constants
and structures. Now conforms to general Haiku naming conventions
rather than BSD ones. Some more constants added/removed based
on the most recent Bluetooth specification.
* Rewrote all code derived from the BSDs to match Haiku conventions
and structures in the driver.
* Dropped the "channel" and "frame" structures from "btCoreData".
Channels are now managed by L2capEndpoints, and "frames" are
now just plain net_buffers without surrounding structures.
This also makes state management much simpler.
* Made it so that actual net_buffers are passed through to the
l2cap_receive function rather than another data structure.
A fake interface address is used to communicate connection
information. (This probably ought to be changed, though.)
* Get rid of l2cap_lower and l2cap_upper abstractions.
Everything related to channel/endpoint management is now
done in L2capEndpoint, while buffer reception is handled
directly in l2cap_receive and elsewhere, same as other drivers.
* Wire up more hooks and fix module flags (needed to be able to
get the module loaded and opening sockets at all.)
* Implement an actual locking strategy in L2capEndpoint
and HciConnection. There's still problems with lifetime
management, but at least thread-safety is mostly handled.
* Create an L2capEndpointManager and use it to manage
the endpoints, rather than having a single (unsafe)
linked-list.
And plenty of other refactorings and cleanups besides.
There's still more to be done for Bluetooth overall, though:
* The "btCoreData" and "hci" modules also badly need a major
overhaul, and should be merged into a single "bluetooth"
bus_manager. They also shouldn't be passing around pointers
to other modules like this.
* There's a number of TODOs/FIXMEs in the L2CAP module, most
notably around timeouts (especially command timeouts) and
parameter validation/specification.

In our C library we try to provide a "clean" POSIX/ISO-C set of include
files that strictly conforming applications can use. However, we also
want to provide some extensions that are commonly available in BSD or
GNU systems.
These are normally provided in a separate directory
(headers/compatibility/bsd) and additionally guarded by compiler defines
that can either be explicitly set, or enabled by default if the language
standard (selected from the compiler command line) is one with GNU
extensions (this is the default for GCC). This is controlled by a header
file called features.h.
However, for some headers it is not so simple to split the GNU
extensions apart from the other parts of the file, because it's not just
extra functions, but additional flags and defines.
So, we need the "features.h" mechanism to be available even in the base
set of headers, but not enable anything if the BSD headers are not in
the search path. The simplest way to achieve this is to have an empty
features.h in the base set of headers, that can then be overriden by the
one in headers/compatibility/bsd if needed.

As a result, using GNU extensions to regex.h required defining __USE_GNU

A version of this feature was originally implemented in hrev50495
that allowed you to scroll through a list of list items while the
mouse was held down updating the selection as you went.
This feature was removed when we switched to selecting on mouse up
in hrev52062 and was never reimplimented when we switched back to
selecting on mouse down in hrev52121.
In BeOS R5 as you scrolled through a single-selection list with the
mouse button held down the selected item appeared to change, but
the selection didn't actually update until you released the mouse
button. The selection never changes on mouse down, only on mouse
up. You could click on one item then move your mouse off the first
item to a second item releasing your mouse button and it would
select the second item without ever selecting the first item.
In this commit we replicate this behavior with one exception, we
always select on mouse down, but still allow the selection to
change on mouse up.
The big difference between this and the BeOS behavior is that on
BeOS you could only select exactly one item on mouse up, while with
this you can select one item on mouse down and a second item on
mouse up.
ScrollToSelection() in MouseMoved() if mouse button is down and
we are not not dragging. This performs auto-scroll.
Create private _DoSelection() method copied from MouseDown().

* Rename the "tun" network device to "tunnel". FreeBSD calls theirs
"tuntap" but speaks of both TUN and TAP devices as interfaces for
tunnels. The other BSDs seem to do likewise.
* Fold the "tun" driver into the "tunnel" network device. The
network device now publishes entries in devfs when interfaces
are created, and unpublishes them when interfaces are destroyed.
This removes the need for the driver and device to communicate
through a file descriptor, and thus allows the receive queue
to be totally eliminated, massively simplifying that logic.

cycles can be "stolen" (the probable cause of the aforementioned
clock drift.)

Based on hamishm's original patch from 2015, but heavily modified,
refactored, and reworked.
From the original commit message:
> When an object is deleted, a B_EVENT_INVALID event is delivered,
> and the object is unregistered from the queue.
>
> The special event flag B_EVENT_ONE_SHOT can be passed in when adding
> an object so that the object is automatically unregistered when an

Modifications to the original change include:
* Removed the public interface (syscalls remain private for the moment)
* Event list queueing/dequeueing almost entirely rewritten, including:
- Clear events field when dequeueing.
- Have B_EVENT_QUEUED actually indicate whether the event has been
appended to the linked list (or not), based around lock state.
The previous logic was prone to races and double-insertions.
- "Modify" is now just "Deselect + Select" performed at once;
previously it could cause use-after-frees.
- Unlock for deselect only once at the end of dequeue.
- Handle INVALID events still in the queue upon destruction,
fixing memory leaks.
* Deduplified code with wait_for_objects.
* Use of C++ virtual dispatch instead of C-style enum + function calls,
and BReferenceable plus destructors for teardown.
* Removed select/modify/delete flags. Select/Modify are now the same
operation on the syscall interface, and "Delete" is done when 0
is passed for "events". Additionally, the events selected can be fetched
by passing -1 for "events".
* Implemented level-triggered mode.
* Use of BStackOrHeapArray and other convenience routines in syscalls.

gcc 13 is confused by the custom bitset implementation, so use the C++
standard one instead.
However, this results in including the C++ <string> header in kernel
code. This doesn't work for gcc2, because of two problems:
- That header includes a declaration of atomic_add that doesn't match
the one in SupportsDefs.h (which can in some cases replace the function
with a #define for an inline version). Adjust the header to use the

Standard C++ headers shouldn't depend on BeAPI ones.
- It also leads to the inclusion of iostream which defined lock and
unlock functions in the global namespace. We don't want these, and they
are not part of the C++ standard, so just remove them.
Ideally we could use std::hash for the GetHashCode implementation, but
that doesn't work because it depends on an helper function that's in
libstdc++, and we can't link that from kernel add-ons.

Previously this just turned the rw_lock into the equivalent of a

were of no use.
Now, we have a per-thread static array which stores the held read
locks, allowing ASSERT_READ_LOCKED_RW_LOCK to work properly,
and allowing multiple readers to be active at a time.
This probably should still remain disabled even on nightly builds,
but at least it's much more useful as a debugging tool than it was

GCC 13 is more strict about what C++ features are available in a freestanding
(= build without standard library) build. The `stdlib.h` and `math.h` headers
are redefined as part of libstdc++. If the object is built as freestanding, it
should be assumed that none of the standard library functions are available.
The solution in Haiku has been to add part of the standard library into the
kernel shared object. The method of exposing them has been to allow the
use of `stdlib.h` and `math.h` in the kernel and in kernel add-ons.
This change allows that approach to continue. What it does, is that it defines
specific headers which will be picked up when a module is built using private
kernel headers. When building for the kernel (or for the boot module), it will
bypass GCC 13's libstdc++ default behaviour of not including the POSIX/platform
header with all the function definitions.
An alternative to be considered for the longer term is to specifically define
the parts of the C/C++ standard library that is available in the kernel in
these headers, or create custom headers when building kernel modules (which is
how Linux approaches it).

- Resize the `page_protections` array in `cut_area` and also shift
the bits if necessary.
- Set the correct protection array as well as the real page
protections for the second area produced by `cut_area`.

This requires the introduction of the flag B_USER_MUTEX_SHARED, and then
actually using the SHARED flags in pthread structures to determine when
it should be passed through.
This commit still uses wired memory even for per-team contexts.
That will change in the next commit.
GLTeapot FPS seems about the same.

* Introduce SWDBM flag similarly to the arm64 port
* Reuse TEX[2] for SWDBM flag which should be availble
to be used by the operating system if TEX remap
is enabled.
* Introduce SetAndClearPageTableEntryFlags for updating
accessed and modified flags atomically
* Startup sequence is handled similarly to accessed flag, i.e.
set Modified flag in initially mapped pages in bootloader and early map.
* Once the kernel initialization has progressed enough,
pages are mapped as read-only and modified flag handling is done
in the page fault handler.
