pwcat: Add list-targets option

The --list-targets option will report on the available
targets for the --target command (and some info about it).

Example:

$ pwplay --list-targets
Available targets ("*" denotes default):
	30: name="alsa_card.pci-0000:00:03.0.playback.3.0" description="Built-in Audio (HDMI 0)" prio=696
	31: name="alsa_card.pci-0000:00:03.0.playback.7.0" description="Built-in Audio (HDMI 1)" prio=632
	32: name="alsa_card.pci-0000:00:03.0.playback.8.0" description="Built-in Audio (HDMI 2)" prio=616
	33: name="alsa_card.pci-0000:00:03.0.playback.9.0" description="Built-in Audio (HDMI 3)" prio=600
*	34: name="alsa_card.pci-0000:00:1b.0.playback.0.0" description="Built-in Audio" prio=936

Getting this working required abandoning the simple stream API, and
the resultant increase in code size.
