837f4f48db kernel/thread: restore signal mask just before returning to userland
* otherwise the signal to be handled might be blocked. fixes #15193
* also remove automatic syscall restart on _kern_select, to match Linux and
BSDs behavior: this fixes parallel build with newer gnu make, which happens
to use pselect.
* also remove automatic syscall restart on _kern_poll.

from https://man7.org/linux/man-pages/man7/signal.7.html
"The following interfaces are never restarted after being
       interrupted by a signal handler, regardless of the use of
       SA_RESTART; they always fail with the error EINTR when
       interrupted by a signal handler: ...
	select(2), and pselect(2)."

"Berkeley-derived kernels never automatically restart select."

522c141d53 [WIP] sd/mmc: enable high speed transfers
- Switch to 25MHz clock
- Switch to 4bit transfers mode (the default is 1bit)

Reading and writing SD cards do not seem to work anymore with these
changes. I get invalid data on read, and on write, an interrupt is never
called in some cases.

68d37cfb3a Fix definition of PAGESIZE and B_PAGE_SIZE
On sparc, the minimal page size we can use is 8K. Since B_PAGE_SIZE and
PAGESIZE defines were hardcoded to 4K, this resulted in a lot of
confusion in all code trying to manipulate pages.

- Remove cpu.h from headers/private/kernel/arch/*. It dates back from
  NewOS and was not used anymore since our kernel uses B_PAGE_SIZE
  (PAGE_SIZE was the only thing defined in this header).
- Add posix/arch/*/limits.h with the arch specific page size and include
  it from the main limits.h.
- Adjust bios_ia32/debug.cpp which was the only place using the
  PAGE_SIZE constant from the deleted headers.
- Change OS.h to define B_PAGE_SIZE to be the same as POSIX PAGESIZE.
- Define PAGESIZE in the build header if the host OS doesn't.

d1fee57dee mmc_disk: add SDHC support.
The main differences:
- The initialization sequence requires an additional command (this was
  already done)
- The layout of the CSD register and the way to compute the device
  geometry from it changes
- The read and write commands parameter is a sector number instead of a
  byte position

7a160a8629 mmc_disk: read using "simple DMA"
The SDHCI spec also offers an "advanced DMA" mode where we can use
scatter-gather lists. It would allow to remove several of the DMA
restrictions, but hardware support for it is optional, so we need this
version anyway.

The geometry is retrieved on demand in the first read or write or in a
call to the get geometry or get device size ioctl. It is not possible to
retrieve it from the device initialization because that is called as
part of the mmc_bus scanning, which needs a specific sequence of
commands and keeps the bus locked to prevent drivers to insert their own
commands in the middle of that sequence.

TODO:
- Move the DMA restrictions definition to sdhci_pci and forward it up to
  mmc_disk (which is the one creating the IOScheduler)
- Decide if we want to keep non-DMA support (probably should, but it
  makes things more complex, because it uses virtual addresses)

74b6097078 sd/mmc: read, naive method
First implementation of reading sectors from an SD card.
This is not the best performance for many reasons:
- No DMA
- Reads only one sector at a time
- Cannot read more than 512 bytes per syscall

Also there are major limitations:
- Cannot read less than 512 bytes. The hardware of course works in full
  sectors. The mmc_disk driver should go through the io scheduler to
  make sure requests have a reasonable size and offset, and nothing
  tries to read just a few bytes in the middle of a sector.
- SD cards only (no SDHC, no MMC)

Architecture problems:
I think too much of the implementation is done in sdhci_pci and should
be moved to the upper layers. However it is difficult to say without
having implemented DMA (which indeed will be at the low level of the
sdhci controller). It doesn't help that the order of operations is a
bit different depending on wether there is DMA or not. In DMA mode you
first prepare the buffer, then run the command. In non-DMA mode you
first send the command, then read the data into the buffer. We need an
API at the mmc_bus level that doesn't care about that low-level detail.
There are other things that the MMC bus should be doing however, such
as switching to different clock speeds depending on which card is
activated and how fast it can go.

At least the following should be done:
- The read method for mmc_bus and sdhci_pci should use a scatter-gather
structure as a parameter instead of a single buffer
- See if can be integrated into ExecuteCommand at sdhci level (it's
essentially a command with an additional data phase)

7c095f4709 BeControlLook: Fix app integration drawing issues
Update BTab::DrawTab() to pass the current index, the index of the
selected tab, and the index of the first and last tabs into
BControlLook::DrawActiveTab() and BControlLook::DrawInactiveTab().
This allows you to draw tabs differently in your BTab or BControlLook
subclass in many different circumstances.

Modify BControlLook API to add indexes to DrawActiveTab() and
DrawInactiveTab() like so:

void DrawActiveTab(..., int32 index = 0, int32 selected = -1,
	int32 first = 0, int32 last = 0);
void DrawInactiveTab(..., int32 index = 0, int32 selected = -1,
	int32 first = 0, int32 last = 0);

These extra indexes are not used by HaikuControlLook which relies only
on if the tab is active or inactive to draw.

Add IndexOf(BTab* tab) method to BTabView and document it to get the
index of the current tab in BTab::DrawTab(). Also add a warning in the
BTabView::DrawTab() method not to use the position and full parameters
anymore, use BTabView::IndexOf(), BTabView::Selection(), and
BTabView::TabCount() to get the info you need.

Using a dynamic_cast to a BTabView in BeControlLook to determine if the
view is derived from a BTabView didn't work in the case of WebPositive.
Furthermore, WebPositive does custom tab drawing which needed to be
updated for alternative control look. These index parameters passed from
BTab to BeControlLook allow us to draw the tab like BeOS without relying
on a dynamic_cast to BTabView to get the info.

Reproduce the functionality described above for BTab in WebPositive's
custom tabs. Eliminate no longer needed code in favor of using indexes.
Update WebPositive custom tabs to use BControlLook::DrawTabFrame()
instead of BControlLook::DrawInactiveTab() matching the update made in
BTabView.

In BeControlLook::DrawTabFrame() fill rect with base color, WebPositive
doesn't draw any tab background, so it expects this work to be done for
it.

Eliminate hasFrames variable from WebPositive.

Rename TabSelected(index) to UpdateSelection(index) in WebPositive to
better reflect its purpose.

Adjusted HaikuControlLook::DrawInactiveTab() to draw the tab borders more
selectively. Only draw border if left border is set for top and bottom tabs
or top border is set for left and right tabs. Undo no longer needed frame
manipulation border drawing workaround in HaikuControlLook::DrawTabFrame().

Draw scroll bar triangle without using DrawArrowShape().

Unlike in HaikuControlLook, DrawArrowShape() is used to draw arrows in
BOutlineListView and menus distinctly from how it draws arrows in scroll
bars. Draw our distinct arrows in DrawSrollBarButtons() instead.

This fixes overflow of time edit up-down arrows in Clock prefs and the
collapse-expand arrow in Deskbar not being vertically centered.

In DrawBorders() only inset if we actually draw the border.

Fix alignment issues with DrawSliderThumb dots for example in
MediaPlayer volume knobs.

Draw using line arrays calling AddLine instead of StrokeLine in
several places.

DrawMenuBar() extends to draw final pixel which eliminates an extra
lines at the end of menu bars.

Truncate button labels better fixing a few issues for example keymap
keyboard layout button labels. Button insets has been updated a bit
to fix drawing issues with buttons missing a border.

Using a dynamic_cast to a BButton to determine if a view is a button
in BeControlLook didn't work in the case of the keymap label. Look for
B_FLAT, B_HOVER, or B_DEFAULT_BUTTON flag in BeControlLook::DrawLabel()
to draw the label inverted on click. Pass the B_FLAT flag from Keymap

This allows you to pass node_ref's around like you can entry_ref's.

Added node_ref_flatten(), node_ref_unflatten() and node_ref_swap() to
MessageUtils. These are close cousins to entry_ref_flatten(),
entry_ref_unflatten(), and entry_ref_swap() but for node_ref's.

Added B_NODE_REF_TYPE to TypeConstants.h in the Support Kit.

Added B_NODE_REF_TYPE to Debugger and ByteOrder in Support Kit,
B_NODE_REF_TYPE is treated the same as a B_REF_TYPE (entry_ref).

Add documentation for new NodeRef methods and B_NODE_REF_TYPE.

331889d067 Kernel/Threads: remove limit on number of dead threads in a team
When a thread is created, it is expected that some other thread (usually the
creating thread) will want to make sure it completes. This is done using the
pthread_join() or wait_for_thread() calls.

It is possible that threads end before another thread waits for its completion.
That's why there is a dead thread list for each team, which holds thread ids
and their exit status so that a call to pthread_join() or wait_for_thread() in
the future can complete succesfully.

The dead thread list was limited to 32 threads per team. If there would be
more, the oldest thread would be kicked off. This could cause issues in
situations where a team would create more than 32 threads, and would start
waiting for their result after they have finished. Some of the calls would fail
because the threads would no longer be in the dead list.

This specifically caused problems for cargo (the Rust package manager), which
could depending on the number of dependencies, could create more than 32
threads. See: https://github.com/nielx/rust/issues/3

This change removes the limit of dead threads within a team. Note that there is
a risk that a badly written program that does not detach or joins its threads
can make this an endless list, but the impact is relatively small (dead threads
only occupy a bit of kernel memory).
