poll: Provide APR_POLLEXCL for exclusive wake up on systems that support it.
epoll has EPOLLEXCLUSIVE, start with that.
poll: Follow up to r1897521: struct epoll_event's events field is unsigned int.
EPOLLEXCLUSIVE is 1u << 28 so it doesn't fit in an int16_t, use unsigned for
the native epoll events type.
poll: Follow up to r1897521: Clarify what APR_POLLEXCL means.
This is to avoid the thundering herd issue when multiple threads/processes
poll on the same descriptor (usually listening/to-be-accept()ed descriptors).
Merge r1897521, r1897548, r1897549 from trunk.
