PulseAudio's JACK modules not being granted real-time scheduling.

On ALSA poll time out, retry polling after executing the recovery.
Retry max limit is set with MAX_RETRY_COUNT.

Currently only poll_result is checked for < 0 before doing the further
processing, and not for timeout. After this movement the revents is checked
only if the poll doesn't timeout.

Currently even on XRUN, the xrun recovery is not executed as the
need_playback or need_capture flag is still true and so it goes
and waits on poll again.

  .travis.yml: Switching to xenial for all other Linux based builds, too.
  systemd/wscript: Making sure to strip trailing new lines from systemd user unit dir.
  .ci/install-deps.sh: Install legacy development packages.
  .ci/install-deps.sh: Testing xenial image (trusty is mega dead) to hopefully get a working systemd development package with headers to be picked up during configure.

aften v0.0.8 is latest released tarball.
https://downloads.sourceforge.net/aften/aften-0.0.8.tar.bz2
Travis builds for OSX use aften v0.0.8 (brew).

More recent aften code has introduced an additional parameter to aften_encode_frame().

The check in wscript compiles a small test program to see if the additional parameter is understood.
If additional parameter 'count' is available, set HAVE_AFTEN_NEW_API.

HAVE_AFTEN_NEW_API is used in common/JackAC3Encoder.cpp to call aften_encode_frame()
either with or without 'count' param.
