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
diagnostic-related overloads bits for clang to it, but I can do that in
another patch.

In the case when there are multiple dependencies on

calling d-tors for some libraries prematurely.
In order to have correct call order loader checks if this

FORTIFY, please see https://goo.gl/8HS2dW . This implementation works
for versions of clang that don't support diagnose_if, so please see the
"without diagnose_if" sections. We plan to swap to a diagnose_if-based
FORTIFY later this year (since it doesn't really add any features; it
just simplifies the implementation a lot, and it gives us much prettier
diagnostics)
