Adds get_state() and ::state-changed signals, that replace connecting

Instead of defining rules manually, use the included make support,
which means Makefiles are less prone to API changes, support
verbosity correctly (instead of inconsistently hardcoding --quiet),
are cleaner to read, and emit GISCAN/GICOMP instead of GEN (which
is nicer).

The library is introspected, and should not require using
Pulseaudio directly.
