don't fail with EINTR in sigtimedwait
...
POSIX allows either behavior, but sigwait is not allowed to fail with
EINTR, so the retry loop would have to be in one or the other anyway.

fix error handling for pthread_sigmask
...
it must return errno, not -1, and should reject invalud values for how.

fix race condition in raise - just mask signals
...
a signal handler could fork after the pid/tid were read, causing the
wrong process to be signalled. i'm not sure if this is supposed to
have UB or not, but raise is async-signal-safe, so it probably is
allowed. the current solution is slightly expensive so this
implementation is likely to be changed in the future.

prevent sigprocmask/pthread_sigmask from blocking implementation signals
...
this code was wrongly disabled because the old version was trying to
be too clever and didn't work. replaced it with a simple version for
now.
