Follow-up of 73721ad4e9.
Forgot to add the fragment parser in the meson build file.

73721ad4e9 mssdemux: improved live playback support
When a MSS server hosts a live stream the fragments listed in the
manifest usually don't have accurate timestamps and duration, except
for the first fragment, which additionally stores timing information
for the few upcoming fragments. In this scenario it is useless to
periodically fetch and update the manifest and the fragments list can
be incrementally built by parsing the first/current fragment.

b35979c31a mssdemux: wrap unmodified data in protection event
PlayReady being the one of the few DRM formats encoding its data with
base64 it was not consistent to have a special case for this. So the
base64 decoding operation now needs to be done by the protection event
consumer, if needed.

0fbee8f374 smoothstreaming: use the duration from the list of fragments if not present in the manifest
Provides a more accurate duration for live streams that may be minutes
or hours in front of the earliest fragment.

e9178fa082 smoothstreaming: implement adaptivedemux's get_live_seek_range()
Allows seeking through the available fragments that are still available
on the server as specified by the DVRWindowLength attribute in the
manifest.

4f6ae1f48c adaptivedemux: Enable bitrate selection for trick mode streaming again
And scale the bitrate with the absolute rate (if it's bigger than 1.0) to get
to the real bitrate due to faster playback.

This allowed in my tests to play a stream with 10x speed without buffering as
the lowest bitrate is chosen, instead of staying/selecting the highest bitrate
and then buffering all the time.

It was previously disabled for not very well specified reasons, which seem to
be not valid anymore nowadays.

42af2d66d8 Add support for Meson as alternative/parallel build system
https://github.com/mesonbuild/meson

With contributions from:

Tim-Philipp Müller <tim@centricular.com>
Matej Knopp <matej.knopp@gmail.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.

7d46d67c59 smoothstreaming: update fps calculation for h264 codec parser API changes
Use new gst_h264_video_calculate_framerate() API instead of fps_n/fps_d
fields in SPS struct which are to be removed.

Apparently H264 content in MSS is always non-interlaced/progressive,
so we can just pass 0 for field_pic_flag and don't need to parse any
slice headers first if there's no external signalling. But even if
that's not the case the new code is not worse than the existing code.

8d445ee758 mssdemux: remove unnecessary check
stream->current_fragment has the value of g_list_previous (iter) which has
just been checked. No need to check it again.

Just to be safe, use a g_assert() to check fragment before dereferencing.

731ab94cc3 adaptivedemux: handle snap seeks
Adaptive demuxers need to start downloading from specific positions
(fragments) for every stream, this means that all streams can snap-seek
to a different position when requested. Snap seeking in this case will
be done in 2 steps:

1) do the snap seeking on the pad that received the seek event and
   get the final position

2) use this position to do a regular seek on the other streams to
   make sure they all start from the same position

More arguments were added to the stream_seek function, allowing better control
of how seeking is done. Knowing the flags and the playback direction allows
subclasses to handle snap-seeking.
And also adds a new return parameter to inform of the final
selected seeking position that is used to align the other streams.

b7a0be23c6 adaptivedemux: replace ghostpad with a standard pad
Handling the ghostpad and its internal pad was causing more issues
than helping because of their coupled activation/deactivation
actions.

As we have to install custom chain,event and query functions it is
better to use a floating sink pad internally in the demuxer and just
use those pad functions to push through a standard pad in the demuxer

bf1246cb13 mssdemux: activate streams before configuring bitrate
Doing the contrary has no effect and the consequence is that playback

5d4388bf9e mssdemux: always use timescale for gst timestamp calculation
Not doing this can lead the demuxer to attempt downloading fragments
for an invalid start time. The server would then send a HTTP
Precondition failed error, the demuxer would try some more times to
download the invalid fragment and eventually error out.

may not be found at the right place, which in turn might

01ccac24fa mssdemux: fix clearing of eos state in pads
The internal pad still keeps its EOS flag and event as it can be assigned
after the flush-start/stop pair is sent. The EOS is assigned from the streaming
thread so this is racy.

To be sure to clear it, it has to be done after setting the source to READY to
be sure that its streaming thread isn't running.
