	syssrc/sys/compat/irix: irix_exec.c irix_exec.h irix_ioctl.c
	    irix_prctl.c irix_prctl.h irix_usema.c irix_usema.h

Log Message:
- add locks to structures used by the /dev/usema driver and the
usync_cntl() system calls.

- when usync_cntl is used and the process is aborted (eg: by kill -9)
libc does not call usync_cntl() to unblock things. We have to cleanup
data allocated in the kernel. This is now done through the emulation
specific exit hook

- IRIX initialize some data in the system part of the PRDA: the pid and
a prid (PRDA ID?). We initialize both to pid.

- Move back struct irix_share_group from irix_exec.h to irix_prctl.h, it
is more revelant here.

- fix a few typos
