2657fc1fdd typefindfunctions: Bail out on huge EBML chunks

1654faad38 typefindfunctions: fix tap typefinder
If we memcmp() 12 bytes we should make sure to get
at least 12 bytes as well, and not just 8 bytes.

Thanks oss-fuzz!

384d27002c typefind: Fix mp3 typefinding with multiple different headers
(yes, this has never worked since it was introduced, don't worry)

If we want to actually detect layer/channels/samplerate changes,
it would be better to:
* not reset the various prev_* variables at every iteration.
* and actually store the values when they change

aa10e82257 typefind: Avoid overflow calculation (image/quicktime)
The qt typefinder uses guint64 values for offset and size calculation
but the typefinder system only supports gint64 values.

Make sure we don't end up using potentially overflowing values.

18, therefore make sure we can read as much.

0bb82827f7 typefind: Expand the search range for HLS detection
HLS files can have arbitrary extra tags in them, and
those can be quite long lines. We need to search
further than 256 bytes sometimes just to get past the
first few lines of the file. Make the limit 4KB,
which matches a typical input block size and should
hopefully cover every crazy input.

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.

9cf5645860 typefind: strengthen check for valid H.263 picture layer
Avoids some false positives leading to miss identification:

* Prevent picture start code emulation for the first 2 bytes read
* Add check for valid "picture coding type" and "PB-frames mode" combination

Additionally, change name on confusingly named TR var to what
it is, the layer's PTYPE.

f188a023c7 typefind: Make the H.264 typefind a tiny bit more lenient.
When we see prefix NALs before a Subset SPS has been spotted,
it might just be because the stream was truncated at the
start, so don't count those as either 'bad' or 'good' packets.

9ef16721ed typefinding: detect MSS manifests without using g_convert()
Embedded systems often have limited charset conversion
functionality, so don't rely on g_convert() (i.e. iconv)
for UTF-16 to UTF-8 conversions, we can easily enough do
that ourselves by converting to native endianness and
then using GLib's helper functions.
