linux emu - peripheral changes
* These are peripheral changes to prepare for the import of the updated
linuxulator:
* hooks (eventhandler) for process creation and process exit.
* splitting up of sys_kevent into sys_kevent + kern_kevent, including
generic copyiin and copyout functions.
Obtained-from: FreeBSD
* adding a p_textnch to store the namecache handle for the .text file.
* minor changes to sysv_sem and sysv_shm to support linux-specific
magic.
* bring in casuword (compare and set userland word)
Obtained-from: FreeBSD
* add a hook for userret from syscall2
Inspired-by: NetBSD
