apr_poll() done.

[Ryan Bloom <rb...@covalent.net>]

Thanks to Will doing the work for Windows, the apr_poll() move is done.
Most of the current platforms are actually using a select() based
implementation, so instead of duplicating logic again, every platform
except for OS/2 is using the Unix poll.c file.

The only implementation that is likely to work currently is the Unix
implementation.  The test suite does have a testpoll.c, which can tell
you if the implementation is working, although it is hard to determine
if the tests were successful.  The important lines are the ones that
give the socket status.  There should be five of these lines, and they
should look like:

Socket 0	Socket 1	Socket 2
No wait	No wait	No wait
No wait	No wait	POLLIN!
No wait	POLLIN!	No wait
No wait	POLLIN!	POLLIN!
POLLIN!	No wait	POLLIN!


The other test that you should run is testpipe.  Remember that
apr_file_read and apr_file_write use apr_wait_for_io_or_timeout, and
that now uses apr_poll().  This means that if the apr_poll()
implementation doesn't work on your platform, CGI scripts and any other
pipe-based request will fail.
