Wrong version got committed, but wasn't noticed since it only builds
with meson, not autoconf.

AIX's poll only allows FD_SETSIZE entries in the fd list, which is
insufficient for expanded MaxClients.
As a bonus, x11perf -noop with ~250 xlogos connected is slightly faster
with pollset:

The epoll code depends on epoll_create1, not epoll_create.

When a client is marked as write blocked, clear any old 'write ready'
bit in the osfds structure so that a new indication of write ready
(which is marked as edge trigggered) will trigger the callback.

If a file descriptor is added or removed from an ospoll callback, then
the arrays containing file descriptor information will have all of
their indices changed, so the loop state is no longer consistent. Just
bail out and let the caller come back around to try again.

Instead of freeing the struct ospollfd elements when the fd is
removed by the user, delay that until epoll is idle so that we are
sure no epoll_event structures could contain the stale pointer. This
handles cases where an fd is removed from the ospoll callback
interface, and also in case the OS keeps stale pointers around after
the call to epoll_ctl with EPOLL_CTL_DEL.

This provides a wrapper around poll or epoll providing a
callback-based interface for monitoring activity on a large set of
file descriptors.
v2: use xserver_poll API instead of poll. Don't use WSAPoll as
that is broken.
