Added files:

flockfile_test.c
Log message:
While almost all the libc locks are taken and released in the same
libc call, flockfile() and ftrylockfile() can be called when
single-threaded and then--while 'holding' the lock--the process can
create another thread, resulting in a broken state. Have the
f{lock,trylock,unlock}file() APIs *always* do real locking so the
exposed state is always consistent.
