466dbe4444 Put back inline definitions if using an old API.
All these inlines were turned in to out of line definitions in L.
This brings us a step closer to being able to just use the current
bionic headers for the NDK, rather than having many old versions of
them.

We'll add more things to this as we discover other warnings we don't
care about.

Raghu Gandham
86d2feef9f Modify MIPS64 stat structure to match a generic one in AOSP.
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.

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.

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

8c4994bbc1 Implement __fsetlocking.
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.

75b99387dd Optimized fread.
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.

19e246dda6 Fix possible leak in pthread_detach.
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.
