This removes the inline assembly code for find_thread

from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility, 
_kfind_thread_ is retained. This will fix some compile 
problems, and provides a cleaner OS.h for future Haiku
versions.
