In addition to being slightly more efficient, this also allows one
to see precisely how many vnodes are currently "alive" across all
mounts via the "slabs" KDL command.
Part of the point of published variables is to make them "shareable",
and not require external synchronization. Requiring the callers
to ensure unpublishing does not occur is thus unreasonable, as e.g.
a variable could be unpublished immediately after being notified.
That is the case for some usages of these variables in the FreeBSD
compatibility layer, which under heavy usage, can and did trigger
use-after-unpublishes and then KDLs, at least in local testing.
Instead, only unlock the hash after we have locked the variable.
This is already done in some other functions, so it's safe to do
it here, too. This way, the variable won't be unpublished
while Notify() is running.
This resolves a TODO, and allows B_KERNEL_RESOURCE_ADDRESS_SPACE
to be a bit more useful, as fragmentation will now turn in
to a low-resource notification.
We never included obprintf in the build, and the real obstack.h
exists in the "extensions" folder. Unfortunately, it seems the
BeOS R5 libroot had an obstack.h in the public POSIX headers
directory and exported the functions, so we cannot remove it
completely just yet.
Seems none of the applications I tested yesterday actually used poll(),
because it was completely broken by this.
The previous code assigned this variable inside a malloc() call, though,
which wasn't all that obvious either.
Reset the value of IsFirstClick to true whenever a new game is
started. Without this fix the board gets confused if there is
a card flipped when a game is restarted.
I can't reproduce any of the other oddities in the ticket but
this fixes the egregious repro case mentioned.

Some improvements to allow setting 8, 15, 16 and 32bit modes, and detect
the correct mode number after patching the BIOS automatically, instead
of hardcoding it.
Also move the patching code to a separate file.
Fixes#10570.

This uses atombios headers to find where in the BIOS the video mode
tables is located. Then, we can replace entries in the table (in a RAM
copy of the BIOS, of course) and inject any video mode we need. To make
the table easy to find, the Atombios headers from the radeon_hd are
reused, but no atombios code execution takes place here.

Get the OEM string from the VESA info block (and also get the memory
size from there while we are at it). If the string is empty, use the
BIOS type (identified in other ways) to still report something.

The VESA standard does not define any way for software to set a custom
video mode, which means normally we would be constrained to whichever
modes the video card manufacturer decided to provide. However, since we
run the BIOS in an emulated environment, it is possible (and even quite
easy) to patch it and inject any video mode we want, provided we know
the format to use and where to put the info in.
This approach was used in the NewOS VESA driver, as well as in
915resolution (a tool that predates the availability of native drivers
for Linux for Intel videocards). Later on it was also used in Chameleon
and Clover, bootloaders that are used for hackintoshes (running MacOS on
unsupported hardware).
This commit implements full support for Intel cards only, AMD and NVidia
will be added later (but there is preliminary code to detect them)

MSI was never implemented in this driver and only used for a log during
initialization. Remove it for now.
This makes it easier to use the driver on non-x86 systems where there is
no MSI.

Removed one of the entries.
Fixed the spelling of some constants: kTooTip* vs kToolTip*
Changing the window title and tab title directly will now
show the same tool-tips as the Terminal settings window.

The options "Refuse in/output format changes" were meant to prevent
format changes of connections on the fly, without tearing down and
establishing a new connection.
The mixer does not support such format changes for input.
With this patch input format changes are refused - the former
default setting.
Output format changes are at least mostly implemented, so we are
allowing format changes here.
Both options get removed from the Audio mixer setup panel of the
Media preferences. The code those settings themselves is kept.
