	    irix_syscallargs.h irix_syscalls.c irix_sysent.c syscalls.master

Log Message:
reworked signal handling:
- do not save/and restore registers that should not be saved and restore
- do give an accurate sigcontext pointer to the signal handler
- do use the struct sigreturna from IRIX.
This eliminates panics and hangs in certain circonstances

Also some cosmetic changes with tabs usage
