Arun Raghavan bf7bc1a55f echo-cancel: Handle underlying sink going away better when autoloaded 
When we the underlying sink/source goes away, there is an intermediate
state where the asyncmsgqs that we were using for the sink-input and
source-output go away. This is usually okay if the sink-input and
source-output are moved to another device, but can be problematic if we
don't support moving (which is the case when the filter is autoloaded).

This becomes a problem because of the following chain of events:

  * The underlying sink goes away

  * Moving the filter sink-input fails (because it is autloaded)
    * At this point the sink-input has no underlying sink, and thus
      no underlying asyncmsgq
    * This also applies to all sink-inputs connected to the echo-cancel
      module

  * The sink-input is killed, triggering a module unload

  * On unlink, module-rescue-streams tries to move sink-inputs to
    another sink, starting with a START_MOVE message

  * There is no asyncmsgq for the message, so we crash
    * We can't just perform a NULL check for the asyncmsgq, since there
      are state changes we need to effect during the move

To fix this, we pretend to allow the move to the new sink, and then
unlink ourselves *after* the move is complete. This ensures that we
never find ourselves in a position where we need the underlying
sink/asyncmsgq to be present when it is not.

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/
