b55dfb5313 Add feature options for almost all plugins
The only plugins remaining are those that haven't been ported to Meson
yet, and msdk. Also, the tests are still automagic.

5199aa60d5 mss: always periodically update the manifest taking the new fragments
Without this, for streams where the content is stored indefinitely and
can be seeked on, the duration would never increase when in paused or,
until we reached near the end of the currently advertised stream (where
the internal fragment parser would see descriptions of new fragments).

0a25fe2893 mssdemux: only add live fragments after manifest fragments
A live manifest may have a set (> LookAheadFragmentCount) of fragments
that have already been served and are stored on the server, maybe
indefinitely.  Adding the parsed live fragments after the manifest
fragments breaks duration reporting and the seekable range.

Fix by only adding parsed fragments outside the list of fragments which
assumes that the fragment list in the manifest is accurate enough to not
stray too far off what's in the retrieved data.

e1b68d9a65 adaptivedemux: answer duration queries for live streams
For duration queries on live streams, adaptivedemux ignores the query.
The problem then is that the query is answered by the downstream
qtdemux element, with the duration of the currently passing fragment.

This commit changes the behaviour of adaptivedemux to answer the duration
queries for live streams, returning GST_CLOCK_TIME_NONE.

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.

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.

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

download the invalid fragment and eventually error out.
