The previous check was causing some problems with platform builds
using the NDK. The new check is more accurate.
Move the C definitions from stdatomic.h to bits/stdatomic.h since
with the new check, we no longer can use the #undef trick to test
them.
Test: build platform NDK with stdatomic.h in pthread.h header
Test: stdatomic bionic-unit-tests

A bit of over-reliance on implementing pthread_cond_clockwait() in
terms of existing functions ended up with a bug that if the condition
variable was initialized to use CLOCK_MONOTONIC, then
pthread_cond_clockwait() would do the wrong thing.
This change corrects that and adds a test for this case.
Test: new and existing tests pthread_cond unit tests

A future version of HWASAN will set pointer tags when taking the address of
a global. This means that we need to untag pointers in a couple of cases
where potential global pointers are passed to an interface that expects
untagged pointers:
- The WriteProtected class, whose only instances are globals, passes its
own address to mprotect. However, our device kernels do not currently
untag pointers passed to mprotect (the proposed upstream kernel patches
do, however, untag these pointers), so once HWASAN starts tagging global
pointers, this will start failing.
- The shadow_load function loads from a shadow that corresponds to the
address space bounds of loaded binaries. Since these address space
bounds are untagged, the pointer needs to be untagged to match.

They're used by 32-bit sanitizers. We used to get these for free (as the
comment says), but the place we got them from changed. Just be explicit.
Longer-term we should fix how we build the sanitizers to only use the
canonical system calls, like they already do for arm64.

snprintf always calls free (on a null pointer) in its epilogue, which
results in infinite recursion if free calls a function that calls
bionic_trace_begin (e.g. when perfetto attempts to lock a mutex in
RecordFree).

On systems where the tcache is disabled, the tcache clear option will

Previously, the linker configuration of an APEX would only be used for
executables located exactly in its `bin` directory. This change
relaxes this condition to also include executables located in any
directory under the APEX's `bin` directory.
This change is needed to support APEX binaries located in directories
under the APEX's `bin` directory that need to use the APEX's linker
configuration (e.g. ART gtests located in
`bin/art/{arm,arm64,x86,x86-64}` in the Testing Runtime APEX).
Test: Run ART gtests on device using the Testing Runtime APEX

__builtin_*_chk will emit warnings when things are trivially broken.
Emitting errors instead is probably better (and we can be a bit smarter
about how we emit code for trivially safe cases.)

Plain __ for generated syscalls didn't mean it was a hidden symbol, it
just meant "please don't use this". We added ___ to signify that a
hidden symbol should be generated, but then we added the map files
anyway so you now have to explicitly export symbols. Given that, this
convention serves no particular purpose so we may as well just use the
nicer names have everything look the same.
