Konstantin Belousov 397d851d66 Reduce the size of the interposing table and amount of
cancellation-handling code in the libthr.  Translate some syscalls
into their more generic counterpart, and remove translated syscalls
from the table.

List of the affected syscalls:
creat, open -> openat
raise -> thr_kill
sleep, usleep -> nanosleep
pause -> sigsuspend
wait, wait3, waitpid -> wait4
