[winealsa] Split driver up in tiny pieces

Resend, this time it applies cleanly.

The audio.c as we have it is way too big to be understandable, it
contains a few helper functions, a lot of init code and the
implementation of wavein, waveout and dsound-like mmap.

This patch splits it up in smaller pieces, which makes the code a lot
more readable, functionality hasn't changed at all.

-** ALSA_PerformDefaultScan
-**  Perform the basic default scanning for devices within ALSA.

-**
-**      Note that Wine, overall, has other mechanisms to
-**  override and specify exact CTL and PCM device names,
-**  but this routine is imagined as the default that
-**  99% of users will use.
-**
-**      The basic algorithm is simple:
-**  Use snd_card_next to iterate cards; within cards, use
-**  snd_ctl_pcm_next_device to iterate through devices.
-**
-**      We add a little complexity by taking into consideration
-**  environment variables such as ALSA_CARD (et all), and by
-**  detecting when a given device matches the default specified
-**  by Alsa.
-**
-**  Parameters:
-**      directhw        If !0, indicates we should use the hw:X
-**                      PCM interface, rather than first try
-**                      the 'default' device followed by the plughw
-**                      device.  (default and plughw do fancy mixing
-**                      and audio scaling, if they are available).
-**      devscan         If TRUE, we should scan all devices, not
-**                      juse use device 0 on each card

+**
+**      We add a little complexity by taking into consideration

+**  detecting when a given device matches the default specified
+**  by Alsa.
