Clang has its own limits.h which is ahead of ours on the inclusion
path. This header uses include_next to include our header, but only
in hosted mode. This means that in freestanding mode we don't get our
limits.h macro definitions, including LONG_BIT. This ends up causing
our signal.h to produce errors when included in freestanding mode on
32-bit platforms.
Fix the errors by replacing usage of LONG_BIT with (8 * sizeof(long))
in the signal headers.

This flag means "$ORIGIN processing required", and since we always
do that, we can claim support for it.

The kernel MTE mode auto-upgrade feature (see mte_tcf_preferred) allows
silent auto-upgrade of Async MTE mode to Asymm or Sync depending on the
OS settings. Relax the tests to allow either Sync or Async faults when
requesting Async mode, and only Sync faults when requesting Sync.
Also tighten the MTENote test to check that both system allocator and
prctl are off when MTE is disabled.

Revert submission 1954983-master-I3030c47be9d02a27505bd4775c1982a20755758c
Reason for revert: PAC has shipped with S, and we're going with app compat outreach rather than regressing security.
Reverted Changes:
I3030c47be:Disable pointer authentication in app processes.

For convenience, builds against musl libc currently use the
linux_glibc properties because they are almost always linux-specific
and not glibc-specific. In preparation for removing this hack,
tweak the linux_glibc properties by either moving them to host_linux,
which will apply to linux_glibc, linux_musl and linux_bionic, or
by setting appropriate musl or linux_musl properties. Properties
that must not be repeated while musl uses linux_musl and also still
uses the linux_glibc properties are moved to glibc properties, which
don't apply to musl. Whether these stay as glibc properties or get
moved back to linux_glibc later once the musl hack is removed is TBD.

Modify libfdtrack to use the normal Unwinder object. In addition,
update the libfdtrack so that it doesn't record frames in
libfdtrack.so rather than skipping frames it thinks will be in
the library.
Modify the malloc debug code to use the normal Unwinder object.
