76f8916b90 Clean up <stdlib.h> slightly.
Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.

6e9e6ad3bf Fix coverage build after adding clang coverage.
Static libraries are painful. Details are in the comment. I'll try to
get prebuilts in to the tree so I can fix this on Monday. Until then,
this isn't actually a regression because we've not had coverage
available for this library until now anyway.

9c3fd59b00 Add a basic NDK compatibility library.
We know we can safely statically link `libm`, since it doesn't have
any dependencies on the OS or the layout of a data type that has
changed between releases (like `pthread_t`).

We can safely statically link `libc_syscalls` because the user can
check for and handle `ENOSYS`.

Update `ndk_missing_symbols.py` to account for symbols that are in the
compatibility library.

Improve `symbols.py` to be able to pull symbols from a static library.

b20c24456e Implement all the POSIX _l functions.
Strictly speaking, this only implements the _l variants of the functions
we actually have. We're still missing nl_langinfo_l, for example, but we
don't have nl_langinfo either.

5ba672ebcb Never use ASAN.
Unless we completely redo how we build bionic (so that the object
files for libc.so get built separately from libc.a), we can't enable
ASAN here, as libc.a gets linked into static executables.

5a69da8d7a Switch to OpenBSD fopen/fclose.
This means all our stdio implementation is now the OpenBSD implementation.
The only thing we lose is the STDIO_THREAD_LOCK calls but they were no-ops
anyway.

We should probably talk to upstream about this. Either fix the locking or,
preferably, encourage them to move away from this pooling (especially since
there's no eviction policy).

a4831cb4a3 Add pthread_gettid_np and re-expose __get_thread for LP32.
A lot of third-party code calls the private __get_thread symbol,
often as part of a backport of bionic's pthread_rwlock implementation.
Hopefully this will go away for LP64 (since you're guaranteed the
real implementation there), but there are still APIs that take a tid
and no way to convert between a pthread_t and a tid. pthread_gettid_np
is a public API for that. To aid the transition, make __get_thread
available again for LP32.

This speeds up the debug malloc code by using the original unwinding code.
The only catch is that it has to link in the libc++ arm unwind code or
there will be crashes when attempting to unwind through libc++ compiled
code.
