Implement POSIX lockf.
This has been requested a few times over the years. This is basically
a very late rebase of https://android-review.googlesource.com/45470
which was abandoned years ago. One addition is that this version has
_FILE_OFFSET_BITS=64 support.
POSIX puts this in <unistd.h>. glibc also has it in <fcntl.h>.
