We need to make sure that having both input and output weighs more for
selecting the default profile than a channel map that matches the
default channel map has.

This adds module-hal-detect-compat.c which when enabled will be compiled
into a module module-hal-detect which simply loads module-udev-detect.
The purpose of this is to allow easy upgrading without breaking
default.pa. Distributions are recommended to enable this to easy
upgrades from HAL versions of PA to udev versions.
Since Fedora does not enable OSS output support at all, but still uses
padsp, and in Gentoo we could also make use of padsp without OSS output
support, split the two things in two parameters, although they both check
for sys/soundcard.h once.
In some situations a rewind request travelling downstream might be
optimized away on its way and an upstream rewind processing might never
come back. Hence, call _process_rewind() before each _render()just to
make sure we processed them all.
Error from snd_pcm_rewind() might mean we just woke up from suspend and
didn't have a chance to try to recover the stream since we didn't write
to it in between. Call try_recover() in such cases.
Note that for this to work kernel must return ESTRPIPE instead of EBADF
for rewind/forward attempts on suspended streams, so that
snd_pcm_recover() can recognize it should snd_pcm_resume() the stream.
This is not the case yet (2.6.31-rc5), patch is available.

Apparently some ALSA drivers aren't happy with getting the buffer size
configured first followed the period size. So swap the order again and
document this for future reference so that we don't turn that around
again.
I hope this is enough, since the removal of the other pa_rtpoll_install()
calls deemed Linux good enough, but said nothing about Solaris, but since
the function is gone there is little more to do.
Move the mainloop to monotonic based time events.
Introduces 4 helper functions:
pa_{context,core}_rttime_{new,restart}(), that fill correctly a
timeval with the rtclock flag set if the mainloop supports it.
Both mainloop-test and mainloop-test-glib works with rt and timeval
based time events. PulseAudio and clients should be fully functional.
This patch has received several iterations, and this one as been
largely untested.
