Linux: Add epoll_pwait2 (BZ #27359)
It is similar to epoll_wait, with the difference the timeout has nanosecond resoluting by using struct timespec instead of int. Although Linux interface only provides 64 bit time_t support, old 32 bit interface is also provided (so keep in sync with current practice and to no force opt-in on 64 bit time_t). Checked on x86_64-linux-gnu and i686-linux-gnu. Reviewed-by: Florian Weimer <fweimer@redhat.com>
