Konstantin Belousov 49ad342cc1 Add _Fork()
Current POSIX standard requires fork() to be async-signal safe.  Neither
our implementation, nor implementations in other operating systems are,
and practically it is impossible to make fork() async-signal safe without
too much efforts.  Also, that would put undue requirement that all atfork
handlers should be async-signal safe as well, which contradicts its main
use.

As result, Austin Group dropped the requirement, and added a new function
_Fork() that should be async-signal safe, but it does not call atfork
handlers.  Basically, _Fork() can be implemented as a raw syscall.

Release of glibc 2.34 added _Fork(), do the same for FreeBSD.
Clarify threading behavior for fork() in the manpage.
