d309877eee Say "Bad file descriptor" rather than "Bad file number". 
This text is actually in POSIX (though it's not mandatory) and it's what glibc
says. Who says "file number" anyway?

e6bb5a2776 Fix optimized fread. 
gcov does writes after reads on the same stream, but the bulk read optimization
was clobbering the FILE _flags, causing fwrite to fail.

I suspect we can simplify this code, but I don't know enough about it
to get involved now.

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.

169eb66451 Add ndk_missing_symbols.py. 
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.

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.
