nptl: remove sigaction, sigprocmask, and sigfillset from libpthread

Having them defined in both places was causing errors with static linking

enable the common code for NPTL

the generic open, close, waitpid, read, write are good for NPTL too
no good reason to have the same sleep in both libc and libpthread (NPTL)
no good reason to add sigwaitinfo, sigtimedwait and sigwait to libpthread (NPTL)

rework cancellation for sigwait, sigtimedwait and sigwaitinfo

sigtimedwait:
- provide __sigtimedwait_nocancel
- use __SYSCALL_SIGSET_T_SIZE instead of _NSIG / 8
- do not provide __sigtimedwait
- guard a section to avoid failure on archs if SI_TKILL/SI_USER are not defined
sigwaitinfo:
- simply use sigtimedwait since that handles cancellation already
sigwait:
- use non-cancellable functions (sigtimedwait, sigsuspend)
- get rid of code already done in __sigtimedwait_nocancel

lseek, lseek64: add cancellation for all THREADS

LT_OLD provides cancellable versions, do it for all THREADS.
llseek.c: use newly added macros for offset handling.
Add a comment about endianness issue around offset.
Compile llseek.c only on 32bit archs.
Provide aliases for 64bit archs or if syscall is not available.
