ec24f4c9f2 asfdemux: More index handling
In the same vein as the previous commit, the end of the file might have been
cut and therefore contains bogus data.

If the object is too short, consider it as garbage and return a non-fatal
flow.

0bbdfa8ee9 asfdemux; Don't assume index is present at end of file
Some files have garbage at the end of the file, don't error out if we don't
find the index there.

Reverts back to previous behaviour (where corrupted/missing indexex were
not a fatal error).

3a25a3a948 asfdemux: adjust segment start to a keyframe ts only for a KEYUNIT seek
... which is how it has always been until changed coincidentally in commit
9ee60482b2 which then prompted commit
dba14178ce to consider ACCURATE as well
to compensate for that in a lateral way

45c7826d76 asfdemux: Handle issues with "empty" files
In some corrupted files, we could end up with no actual streams
being exposed.

In those cases, make sure we properly propagate the failure all
the way to the loop function. This avoids ending up in cases where
we are neither EOS'd nor ERROR'd out from a pipeline point of view.

c8260a1545 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.

6ff1c761e4 asfdemux: fix seeking back after EOS has been reached in push mode
Fix seeking when demuxer is in INDEX state. This happens when we
reached the end of the stream. It should still be possible to do
a flushing seek and seek back to any other position though. Instead
the demuxer would just go straight to EOS again instead of going
back to processing packets again from the new position.
