Ahmed S. Darwish f5315113a5 pacat: Synchronize STDIN and "write stream ready" events 
Users reported pacat crashes when playing certain multi-channel
audio. For example:

  pacat --channels=2 /dev/zero    works
  pacat --channels=3 /dev/zero    pa_stream_write() failed: EINVAL
  pacat --channels=4 /dev/zero    works
  pacat --channels=5 /dev/zero    pa_stream_write() failed: EINVAL

pacat audio playback is pipe-like, from STDIN to PA write stream.
Meanwhile STDIN "ready to read" events got regularly triggered
before the write stream was even created, or at moments where the
stream could not accept any more audio.

In these out-of-sync cases, the write stream could not report the
appropriate buffer lengths it accepts, thus a default of 4K bytes
was chosen -- compatible by luck with some channel counts and
incompatible with others.

Instead of choosing a faulty default in these scenarios, mute the
the STDIN events until the write stream is available & queriable.

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/
