Subject: [PATCH] build: Add bash completion

This patch adds bash completion for pulseaudio and all of the utilities.
Channel maps and properties are not yet completed.

This should make mostly pactl/pacmd more useful for bash users.

Thanks to Denis Kasak for the awk magic (fetching ports and profiles
from the card info).
