It seems to me that the proper way to do this is for the pulseaudio
libasound plugin to detect an environment variable, and then
func_load_if_running does nothing in that case.

Alsa maintainers, what do you think? Does it make sense to you? The
code already checks for the PULSE_INTERNAL envvar, but abusing this
variable would be ugly. Adding a similar check for a variable named
like PULSE_DISABLE_ALSA_PLUGIN or something like that should be very
simple.
