Konstantin Belousov cb5c4b10ba Add two rtld exported symbols, _rtld_atfork_pre and _rtld_atfork_post. 
Threading library calls _pre before the fork, allowing the rtld to
lock itself to ensure that other threads of the process are out of
dynamic linker. _post releases the locks.

This allows the rtld to have consistent state in the child. Although
child may legitimately call only async-safe functions, the call may
need plt relocation resolution, and this requires working rtld.
