Alexander E. Patrakov 768c80f3c3 alsa: reread configuration when opening new devices 
If a card has been hot-plugged after pulseaudio start, alsa-lib still has
old configuration in memory, which doesn't have PCM definitions for the
new card. Thus, this error appears, and the device doesn't work:

I: [pulseaudio] (alsa-lib)confmisc.c: Unable to find definition 'cards.USB-Audio.pcm.front.0:CARD=0'
I: [pulseaudio] (alsa-lib)conf.c: function snd_func_refer returned error: No such file or directory
I: [pulseaudio] (alsa-lib)conf.c: Evaluate error: No such file or directory
I: [pulseaudio] (alsa-lib)pcm.c: Unknown PCM front:0
I: [pulseaudio] alsa-util.c: Error opening PCM device front:0: No such file or directory

The snd_config_update_free_global() function makes alsa-lib forget any
cached configuration and reparse all PCM definitions from scratch next
time it is told to open anything.

The trick has been copied from Phonon.

HACKING:
	In order to run pulseaudio from the build dir __OPTIMIZE__ should be
	disabled (look at src/pulsecore/core-util.h::pa_run_from_build_tree()),
	this can be done by passing "CFLAGS=-O0" to the configure script:
	  ./autogen.sh
	  CFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3" ./configure
	  make
	  ./src/pulseaudio -n -F src/default.pa -p $(pwd)/src/
