The kernel version of the stat structure is used during the syscalls. After the syscall,
the kernel stat structure is converted to match the generic one. Eventually we would like
the generic stat structure and related syscalls be added to MIPS64 kernel, removing the
thunks added to AOSP.

Move various mips-only things into the arch-mips directory. As soon as mips
writes assembler replacements, we can remove these.

Interestingly, this mostly involves cleaning up our implementation of
various <string.h> functions.

The code now compiles with all combinations of DEBUG and
DEBUG_DATA except DEBUG_DATA=1, DEBUG=0, which is unsupported.

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.

This text is actually in POSIX (though it's not mandatory) and it's what glibc
says. Who says "file number" anyway?

gcov does writes after reads on the same stream, but the bulk read optimization
was clobbering the FILE _flags, causing fwrite to fail.

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.

ndk_missing_symbols.py pulls libc.so and libm.so off a running device
or emulator and shows the list of symbols that are in the current
bionic that aren't available on the target.

The old __isthreaded hack was never very useful on Android because all user
code runs in a VM where there are lots of threads running. But __fsetlocking
lets a caller say "I'll worry about the locking for this FILE*", which is
useful for the normal case where you don't share a FILE* between threads
so you don't need any locking.

This is correctness rather than performance, but found while investigating
performance.

This makes us competitive with glibc for fully-buffered and unbuffered reads,
except in single-threaded situations where glibc avoids locking, but since
we're never really single-threaded anyway, that isn't a priority.

If pthread_detach() is called while the thread is in pthread_exit(),
it takes the risk that no one can free the pthread_internal_t.
So I add PTHREAD_ATTR_FLAG_ZOMBIE to detect this, maybe very rare, but
both glibc and netbsd libpthread have similar function.
