With the removal of apr_poll(), the apr_wait_for_io_or_timeout() function

needed to be rebuilt. Specifically, it needs a pollset, but we don't want
to allocate that all the time. Thus, we need to create it once at socket
or file creation time, and then reuse that pollset.

NOTE: this makes the library compile, but some of the test programs may
not. I have also not verified this work yet (in favor of just getting it
to at least compile...)

For the apr_arch_*.h files, I added a pollset member to the file and
socket structures.

For the various open/dup/etc functions, I added the creation of that
pollset whenever a file or socket is created.
(I may have missed some and will verify further)

For the socket create and sendrecv function, I added the creation of the
pollset.
(again, may have missed some, but if everybody uses alloc_socket, then we
 should be okay)

* support/unix/waitio.c: rebuild in terms of the pollset
