bionic/libc/upstream-freebsd/freebsd-compat.h
Elliott Hughes ab61eb366a Switch to upstream sleep(3) and usleep(3).
Also fix the signature of usleep, and the definition of useconds_t which
should be unsigned, as the 'u' in its name implies.

This patch also cleans up the existing FreeBSD hacks by moving the libm
stuff from <sys/cdefs.h> to a libm-private header, and adding comments
about the hacks we use to build FreeBSD source.
