Guard the GNU strerror_r with an API check.
The deprecated headers have always had only the POSIX definition
available (and it's always been available). With the unified headers
as they are now, we actually make it unavailable for C++ users (C++
implies _GNU_SOURCE) targeting below M. Adding this guard means that
pre-M users will still at least get the POSIX one.
It's not great that moving to M as your target API will actually
change the signature of your strerror_r, but I don't see a better
option here (not until we have the compatibility library, anyway).

Be more strict about using invalid `pthread_t`s.
Another release, another attempt to remove the global thread list.
But this time, let's admit that it's not going away. We can switch to using
a read/write lock for the global thread list, and to aborting rather than
quietly returning ESRCH if we're given an invalid pthread_t.
This change affects pthread_detach, pthread_getcpuclockid,
pthread_getschedparam/pthread_setschedparam, pthread_join, and pthread_kill:
instead of returning ESRCH when passed an invalid pthread_t, if you're
targeting O or above, they'll abort with the message "attempt to use
invalid pthread_t".
Note that this doesn't change behavior as much as you might think: the old
lookup only held the global thread list lock for the duration of the lookup,
so there was still a race between that and the dereference in the caller,
given that callers actually need the tid to pass to some syscall or other,
and sometimes update fields in the pthread_internal_t struct too.
(This patch replaces such users with calls to pthread_gettid_np, which
at least makes the TOCTOU window smaller.)
We can't check thread->tid against 0 to see whether a pthread_t is still
valid because a dead thread gets its thread struct unmapped along with its
stack, so the dereference isn't safe.
Taking the affected functions one by one:
* pthread_getcpuclockid and pthread_getschedparam/pthread_setschedparam
should be fine. Unsafe calls to those seem highly unlikely.
* Unsafe pthread_detach callers probably want to switch to
pthread_attr_setdetachstate instead, or using
pthread_detach(pthread_self()) from the new thread's start routine
rather than doing the detach in the parent.
* pthread_join calls should be safe anyway, because a joinable thread
won't actually exit and unmap until it's joined. If you're joining an
unjoinable thread, the fix is to stop marking it detached. If you're
joining an already-joined thread, you need to rethink your design.
* Unsafe pthread_kill calls aren't portably fixable. (And are obviously
inherently non-portable as-is.) The best alternative on Android is to
use pthread_gettid_np at some point that you know the thread to be
alive, and then call kill/tgkill directly.
That's still not completely safe because if you're too late, the tid
may have been reused, but then your code is inherently unsafe anyway.

Add __system_property_wait and return the serial in __system_property_read_callback.
In order to implement android::base::WaitForProperty well, we need a way to
wait not for *any* property to change (__system_property_wait_any), but to
specifically wait for the property represented by a given `prop_info` to
change.
The android::base::WaitForProperty implementation, like attempts to cache
system properties in the past, also needs a way to keep serials and values
in sync, but the existing functions don't provide a cheap way to get a
consistent snapshot. Change the __system_property_read_callback callback's
type to include the serial corresponding to the given value.
Add a test, slightly clean up some of the existing tests (and name them to
include the names of the functions they're testing, in our usual style).

Match __bos0 to __pass_object_size0 in FORTIFY
pass_object_size(N) forwards the result of __builtin_object_size(param,
N) to a function. So, a function that looks like:
size_t foo(void *const p __pass_object_size) { return __bos0(p); }
int bar = foo(baz);
would effectively be turned into
size_t foo(void *const p, size_t sz) { return sz; }
int bar = foo(baz, __bos(baz)); // note that this is not __bos0
This is bad, since if we're using __bos0, we want more relaxed
objectsize checks.
__bos0 should be more permissive than __bos in all cases, so this
change Should Be Fineā¢.
This change also makes GCC and clang share another function's
implementation (recv). I just realized we need to add special

isnan and isinf aren't functions.
isnan was a function in POSIX in 1997, but changed to a macro only in 2004
to align with the C standard. isinf wasn't in POSIX until 2004, where it
appeared as a macro only (but other C libraries already had it as a
function).
Now the C++ standard has added ::isnan and ::isinf functions with different
signatures from the historical ones, so we need to move our historical cruft
out of the way.
We'll keep the implementations for backwards compatibility.

Do not load second copy of a library into same namespace
This workaround was introduced in M in order to make sure
that linker loads libraries provided in apk in case a library
with the same name was loaded by the system.
This is no longer a problem starting with Android N because
app is using different namespace and therefore does not see
libraries loaded by the system.

choice between primitives.
Test: Built and ran benchmark on Angler repeatedly. Manually confirmed
