alsasink can now detect a resume, stop and pause. The sink is now
properly paused using snd_pcm_pause(), and without losing any data

ac5d0f7da6 alsa: Implement a DeviceProvider
Removing gstalsadeviceprobe.[ch] as it was a relique from the 0.10
century.

This doesn't implement device monitoring but only probing, monitoring
should be implemented in its own commit.

ed33011502 alsasrc: Don't use driver timestamp if it's zero
Some alsa interfaces don't provide timestamps and thus always set the timestamp to zero.

d64a4b7a69 Revert "alsa: Implement a DeviceProvider"
This reverts commit 69c3c31608.

All devices have the same name, they are duplicated with pulseaudio one
and the provided does not respond to HW being plugged/unplugged. I think
it's not ready for 1.16.

4f88125b3d alsasrc: lock calls to snd_pcm_delay() with mutex as in alsasink
Alsasrc introduced delay_lock in commit 519f85a43e73efb8f3fb2c7be45226e
because alsa-lib is not thread safe for the same handle.
Alsasrc uses the same threading pattern, it should be locked too.

feacb875a4 alsamidisrc: Improve buffer timestamping
Make buffer timestamps more accurate and, more importantly, actually
representative of the MIDI events timing.

Previously, buffers were only sent with timetamps aligned at a 10ms
boundary which was just wrong, now the buffer timestamp represents the
real time of the MIDI event.

Conveniently, the ALSA sequencer API supports scheduling events in the
future so the sequencer infrastructure can be used to have the tick
delivered at the right time, avoiding any custom scheduling mechanism.

The ticks scheduling starts on the first transition to PLAYING, and the
delay is also calculated when the pipeline goes into PLAYING.

5c4f4ac1bd Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Jussi Pakkanen <jpakkane@gmail.com> (original port)

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded

... and many more. For more details see:

http://blog.nirbheek.in/2016/07/building-and-developing-gstreamer-using.html

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.

6e7fa6659f alsa: properly convert position-less channels from ALSA
The only way for ALSA to expose a position-less multi channels is to
return an array full of SND_CHMAP_MONO. Converting this to a
GST_AUDIO_CHANNEL_POSITION_MONO array would be invalid as
GST_AUDIO_CHANNEL_POSITION_MONO is meant to be used only with one
channel.

Fix this by using GST_AUDIO_CHANNEL_POSITION_NONE which is meant to be
used for position-less channels.

4fe12c1b09 alsa: Use 8 bit pointer type for byte-based pointer arithmetic
Usually these loops only run once, so there's no problem here. But sometimes
they run twice, and by adding the number of bytes to a 16 bit pointer type we
would advance twice as much as we should.

Also use snd_pcm_frames_to_bytes() in alsasrc to calculate
the number of bytes to skip, same as we do in alsasink.
