string: Add sigabbrev_np and sigdescr_np
The sigabbrev_np returns the abbreviated signal name (i.g. "HUP" for
SIGHUP) while sigdescr_np returns the string describing the error
number (i.g "Hangup" for SIGHUP). Different than strsignal,
sigdescr_np does not attempt to translate the return description and
both functions return NULL for an invalid signal number.
They should be used instead of sys_siglist or sys_sigabbrev and they
are both thread and async-signal safe. They are added as GNU
extensions on string.h header (same as strsignal).
Checked on x86-64-linux-gnu, i686-linux-gnu, powerpc64le-linux-gnu,
and s390x-linux-gnu.
