739d4da07b amd_pstates: introduce a AMD P-states driver for Ryzen with the CPPC feature
tested on Zen2 (Ryzen 3 5300U)
This support was submitted in October for inclusion in Linux.
Haiku supports only two profiles. We could probably add some more, and let the driver says which it supports.

241f109ccb View: provide the transform between different coordinate spaces
There's currently no way for an application to convert between view and
drawing coordinates with a drawing states stack without keeping track of
all the transformations itself, which is not very convenient for helper
or library functions.

Handle other spaces too, for good measure.

32a71a00aa stdint.h: fix definition of UINT8_MAX, UINT16_MAX, UINT8_C and UINT16_C
C99 chapter 7.18.2, Limits of specified-width integer types:

"This expression shall have the same type as would an expression that is
an object of the corresponding type according to the integer promotions."

C99 chapter 6.3.1.1:

"If an int can represent all values of the original type, the value is
converted to an int; otherwise, it is converted to an unsigned int.
These are called the integer promotions."

Therefore, UINT8_MAX, UINT16_MAX, UINT8_C and UINT16_C should be signed.

This prevents building WebKit with -Werror.

1111dda699 NetServices: Add libnetservices2.a from dev/netservices into master
The overall design does not deviate much from my proof of concept [2] and that still makes a good read to
understanding the overall architecture. If you want to get a sense of how it is built up, the API comes with
full doxygen documentation for the public API [3], and I have also done a PoC change for HaikuDepot which is
useful as an illustration on what the impact for the user of the new library is. [4] There is also a test suite
that may give some insight into the day to day ergonomics of the API [5].

The current state is that I am fairly confident that many HTTP requests will actually work, but I do expect
rough edges with a protocol with this many diverse implementations. There is also a list of features yet to be
implemented on Trac [6]. Additionally, I still want/need to do performance testing.

The goal of merging the kit right now is to start making it available for more uses, and through that also give
a chance to shape its future. There are also some design decisions that need review, most notably I expect some
discussion around the uses of C++ 17 idioms (like std::optional and std::string_view) and around the use of
exceptions for error handling.

The impact of merging right now should be near zero: the netservices2 kit lives in its own header space, and
builds into its own static library (libnetservices2.a). It is not yet used in any of the apps in our
repository.

The branch does remove the deprecated services kit from the libnetapi.so library, though it leaves
libnetservices.a intact. After our previous announcement to remove it after beta 3, this should be expected.

8672fc2739 InterfaceDefs: Adjust and introduce new spacing/insets constants.
* Nothing in the tree and few things outside it used BIG_{SPACING|INSETS};
   it seems a value of 15px (at default font size) is not that useful.
   There are, however, a lot of things around the tree that use multiples
   of 20px. So, make BIG be that, with the intent to replace those
   with BIG directly.

 * Introduce CORNER_{SPACING|INSETS}. There are a lot of applications
   (e.g. Tracker, Terminal, Debugger etc.) which use scroll bar width/height
   to metrically align controls with the window frame or with some other
   control which contains scroll bars. Rather than have to invoke
   BScrollBar or BControlLook directly to get the value, we should just
   derive the size of scrollbars from a spacing constant instead
   and get rid of the custom function. (For now it is just replaced.)
   This reuses the old values for BIG, as it is equal to 14px at default.

 * Introduce BORDER_{SPACING|INSETS}. This is equal to the typical border
   size of 1px at default font size (or lower) and uses floor() instead of
   ciel() to compute what the size should be (i.e. it will remain 1px
   at 150%/18pt and only go up at 200%/24pt.) This will allow a lot of
   the hardcoded border sizes around the tree and elsewhere to use
   ComposeSpacing() instead.

71e29bbeea NetServices: format code using haiku-format
This commit formats all the netservices2 code with the `haiku-format` tool from
https://github.com/owenca/haiku-format (commit aa7408e), with the following
customizations:
 * SpaceBeforeRangeBasedForLoopColon is set to false
 * Braces before a catch block are not wrapped
 * Most headers, except for ExclusiveBorrow.h, have been manually reformatted
   to adhere to Haiku's header format (issue #19 in the repository)

b2c77ad27a Network: Add a BNetworkDevice::GetNetworks() method and use it in the GUI.
The GetNextNetwork() method is really inefficient: it fetches all the
networks at once from the kernel every single time and then winds
up returning only one of them. In parts of the GUI that iterate over
all networks more than once per refresh (sometimes within a loop, even!)
this was often a noticeable lag on the GUI, especially with OpenBSD
drivers which have extra overhead to do struct translation in the
ioctl handler.

Now, we have a way to fetch all scan results at once and just iterate
over them as many times as we need, and this is what NetworkStatus
and Network preferences now do, saving lots of time and effort.

8e17b43da6 kernel/device_manager: Implement B_GET_DRIVER_FOR_DEVICE
for legacy and new drivers.

This is an opcode for ioctl that can be used on almost any device entry found in /dev.
When used, ioctl will fill a buffer with the absolute path to the driver file that is
being used by the device.

This opcode was available in BeOS R5, though remained unimplemented in Haiku since
the introduction of the Device Manager almost two decades ago.

Original change by Jacob Secunda.

688acf41a3 add physical_block_size field where applicable
only scsi_disk checks the actual value, other drivers take the logical block size.

This change reports the physical block size from the disk rather than the block
size used by IDE/SATA/SCSI commands. On typical modern SATA disks, the SATA
commands will use 512 byte blocks, but the disk will actually read and write
4K blocks internally. This is only of importance for partition alignment for DriveSetup,
and is independant of file systems or partitioning systems. This could also influence
the recommended block size for some file systems.

d469ab6d6c libroot: Remove unused files
Not referenced in any Jamfile, does not compile, untouched since
2003 except for a few coding style and cppcheck fixes. The functionality
is implemented elsewhere in the disk device manager and userland
filesystem add-ons for DriveSetup.

66af664352 Drop the unused TTY bus_manager.
Just stubs and not actually used.
We have a TTY module (and driver) which supplant it.

b6b61bd39f general/logs: Ensure all logs start with THING:
* 90% of our logs start with some context on what is
  generating a log message (thing:)
* Things following this logging model however do "thing [time"
  which is inconsistent
* Being consistent will allow us to start scanning logs in a
  smart way and try to analyze patterns of what is throwing
  errors, etc in an automatic way.
  aka /^(service/driver/etc)\:/

27196c4068 NetServices: use BBorrow<BDataIO> for custom body targets

1e22817dfb NetServices: add the BExclusiveBorrow<T> smart pointer
This smart pointer is designed to help with putting some explicitness and
safety around the case where someone will use their own object that implements
the BDataIO interface to store the body of a network request. By default,
BDataIO objects do not require or enforce thread safety. Since accessing these
unsynchronized objects between two threads is undefined behavior, it should be
explicitly discouraged.

The BExclusiveBorrow/BBorrow smart pointer helper helps solve that by enforcing
the limitations on using an unsynchronized object in two threads. When used
correctly, there is a runtime check on incorrect use by the developer. This
should help write better code.

The design is based on shared_ptr, including having an admin block akin the
control block, that manages the internal object. This type-erased admin block
has the advantage that it allows the owner to have a different type than the
borrower. It also handles cases where the lifetime of the borrower is longer
than the owner: the borrower can continue to use the object until they want to
return it, after which it will be cleaned up. This will make it possible to do
some fire and forget pattern in the network services kit, where someone may
just wants to create a file and borrow it to the network request, and care
about further processing the file in the future.
