pselect: Use linux pselect syscall when available
Linux has a pselect syscall since 2.6.something. Using it rather than emulating it with sigprocmask+select+sigprocmask is smaller code, and works properly. (The emulation has race conditions when unblocked signals arrive before or after the select) The tv.nsec >= 1E9 handling comes from uclibc's linux select() implementation, which itself uses pselect() internally if the pselect syscall exists. I though it would be good to do the same here. Note that although the libc pselect() API has 6 arguments, the linux kernel syscall as 7 arguments. There is an extra, somewhat vestigial, sizeof the signal mask argument. Signed-off-by: Nicolas S. Dade <nic.dade@gmail.com>
