Removed strcmp, strlen, and memset calls from table.h and replaced them
with internal functions.

The printf parser uses errno for setting up the %m conversion. It was
presumably getting this include indirectly until a recent change. This
patch adds a direct dependency to fix it.
The previous internal fcntl implementation modified errno directly, this
patch fixes that. This patch also moves open and close into OSUtil since
they are used in multiple places. There are more places that need
similar cleanup but only got comments in this patch to keep it
relatively reviewable.

Fixes a couple of bugs found when building. The PR to enable the headers
can be found here: #144114.
- math.yaml: float128 guard
- wchar.yaml: __restrict keyword order
This reverts commit a93e55e57e and fixes
build and test failures:
* Proper include added to setvbuf_test.cpp
* fgetc/fgetc_unlocked/fgets tests are ported to ErrnoSetterMatcher and
are made more precise. This fixes inconsistencies between expectations
in regular and GPU builds - ErrnoSetterMatcher is configured to omit
errno matching on GPUs, as fgetc implementation on GPU doesn't set
errno, in contrast to Linux.
Reduce the direct use of libc_errno in stdio unit tests by adopting
ErrnoCheckingTest where appropriate.
Also removes the libc_errno.h inclusions from stdlib.h tests that were
accidentally added in d87eea35fa
Summary:
We need to set the bitfield memory to zero because the system does not
guarantee zeroed out memory. Even if fresh pages are zero, the system
allows re-use so we would need a `kfd` level API to skip this step.
Because we can't this patch updates the logic to perform the zero
initialization wave-parallel. This reduces the amount of time it takes
to allocate a fresh by up to a tenth.
This has the unfortunate side effect that the control flow is more
convoluted and we waste some extra registers, but it's worth it to
reduce the slab allocation latency.
After changing mbstate_t to mbstate we forgot to change the
character_converter files to reflect it.

* Get rid of libc_errno assignments in str_to_* __support tests, since
those API have been migrated to return error in a struct instead.
* Migrate tests for atof and to strto* functions from <stdlib.h> and for
strdup from <string.h> to use ErrnoCheckingTest harness.
I'm setting up a buildbot for arm32 using qemu and qemu doesn't support
PR_GET_THP_DISABLE.
Disable the test for now while we figure out what to do about that.
Also disable for riscv because we may do the same for riscv buildbots.
Add `CLOCKS_PER_SEC` and the older `CLK_TCK`. Allows the user to define
a `__CLK_TCK` to override if necessary.
Also add an extra column for embedded AArch64 in `time.rst`
The string_utils.h file previously included both memcpy and bzero. There
were no uses of bzero, and only one use of memcpy which was replaced
with __builtin_memcpy.
Also fix strsep which was broken by this change, fix a useless assert of
"sizeof(char) == sizeof(cpp::byte)", and update the bazel.
Summary:
This improves performance by reducing the amount of RMW operations we
need to do to a single slot. This improves repeated allocations without
much contention about ten percent.
