Our dirent structure is "slim": it has a flexible-length array at the
end which must be allocated to whatever size the consumer wants. However,
we use [1] there and not [0] or [], which meant GCC thought it was not
a flexible-length array, and so it optimized various string accesses
that it assumed must be always false. Among these was BDirectory's
check for "." and "..", and so that resulted in infinite loops.
When changing our dirent structure to a proper FLA instead of [1],
GCC then throws errors on LongDirEntry as it has data "after" the
FLA; which is what we want, but there is no way to tell GCC that.
So now we use a union instead, which is the proper way to statically
allocate a FLA.
This is part of #17389, but the real fix requires changing our dirent
structure, which is coming in a separate commit.
As suggested by PulkoMandy. This was done before my commits yesterday,
but those just reverted patches that had only been in since May,
so it's not clear how much this is actually needed. Nonetheless
it seems like the more correct thing to do.
While FreeBSD and glibc feature-guard it, they also feature-guard
a lot of other things that we don't, and musl does not guard it,
so it seems more than safe enough to leave it unguarded.
Fixes compilation errors with GCC 11. (The other possible solution
was including features.h in more places, but this seems simpler.)

This cuts out almost 40,000 lines of these headers. (I did something similar
in the atheroswifi AR93xx/94xx driver when importing it from FreeBSD,
which had a lot more than 40,000 lines.)
The code in this module was derived from the one in driver/tty. However,
the driver uses a shared lock between the master and slave side of a
TTY, and this was changed to use two separate locks. The approach with
two locks does not work. It seems the change was unfinished and the
second TTY was never locked. But attempting to lock it will result in
lock inversion problems, unless we do complicated things (try to find
which of the two TTY is the master side, and lock that first, for
example). It is simpler to restore the shared lock as used in the
driver.
To set up the shared lock, I modified the tty_create function to take a
pointer to the master TTY when creating the slave. Maybe it makes more
sense to create both sides in the same call, create_tty_pair?
However, this does not work as easily as I wanted, because there is some
recursion going on: at least in one case, the tty_control function is
calling the driver's tty_service function, which in turns attempts to
call back into tty_control for the "other side" TTY. To handle this
case, replace the mutex with a recursive_lock.
Fixes#17091, where the root problem was access to
other_tty->select_pool without locking. This was also made unconvenient
to debug because select_pool objects are self-deleting, when the last
item in the pool is removed. As a result, the code accessing it without
log would suddenly find out that the data it was accessing had been
freed and erased.
This also makes the TTY code in driver/tty and generic/tty a bit more
similar than it was before, and brings us one step closer to merging the
two together. There are still two main differences and I don't know
enough about TTY to decide if they are important, and which version
should be kept:
- The driver has extra code for "background" read and write. I don't
know what this is used for.
- The driver has a single "settings" instance shared by a master and
slave TTY, while the module has two separate instances, but seems to
copy one to the other. I'm not sure which approach is correct.

These were used in function_remapper.cpp but can be used elsewhere too,
so move them to a private header. Also use them for the stack protector
hidden function definition (probably not so useful since gcc2 doesn't
support using the stack protector anyway?).
The gcc2 way to make a symbol hidden is to manually generate the .hidden
directive in the assembler output. This is not perfect: it is hard to
use for C++ functions and methods (manual mangling of the name is
needed), and inline assembler can only be inserted inside functions. But
the alternative is patching gcc2 to add support for the function
attribute, and I don't want to dig into that today.
This is an old version of libc++ that was imported in an early attempt
of building Haiku with clang. It is currently not used for anything. In
fact there never was a Jamfile to build it.

this is a big difference with RGB24_BIG and RGBA32_BIG, in which case _BIG
means the order is RGB (BGR) and not BGR (BGRA).
BGR48, BGRA64 could indeed be added, if needed.
I chose 0x11 and 0x12 arbitrarily, but given the order of channels 0x1011

It was removed in hrev55422 as we never had declared it in any headers.

This is a source compatibility break from BeOS, but should not
be an ABI one (I checked, the symbols are identical.)
Also use "= {}" in the definitions of the fields. We use this
in plenty of places in the kernel, so it should be OK for GCC2.
