Peter Harris 83c04ee6ea os: Add epoll-like pollset implementation for AIX
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:

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
