0d617885f1 tagdemux: Properly propagate sequence numbers
If we received a time segment from upstream, we need to make sure we propagate
it downstream with the same sequence number.

0b6bbce012 Remove the uninstalled term
Remove the symbolic link `gst-uninstalled` which points to `gst-env`.
The `uninstalled` is the old name and the project should stick to a
single name for the procedure.
Remove the term from all the files, exceptions are variables from
dependencies like `uninstalled_variables` from pkgconfig and
`meson-uninstalled`.
Adjust mentions of the script in the documentation and README.

3ddb4c6f0e tagdemux: Fix crash when presented with malformed files
There's a race condition in gsttagdemux.c between typefinding and the
end-of-stream event. If TYPE_FIND_MAX_SIZE is exceeded,
demux->priv->collect is set to NULL and an error is returned. However,
the end-of-stream event causes one last attempt at typefinding to occur.

This leads to gst_tag_demux_trim_buffer() being called with the NULL
demux->priv->collect buffer which it attempts to dereference, resulting
in a segfault.

The malicious MP3 can be created by:

printf "\x49\x44\x33\x04\x00\x00\x00\x00\x00\x00%s", \
    "$(dd if=/dev/urandom bs=1K count=200)" > malicious.mp3

This creates a valid ID3 header which gets us as far as typefinding. The
crash can then be reproduced with the following pipeline:

gst-launch-1.0 -e filesrc location=malicious.mp3 ! queue ! decodebin ! audioconvert ! vorbisenc ! oggmux ! filesink location=malicious.ogg

f1bb2c76c6 meson: update for dep.get_pkgconfig_variable() deprecation
... in favour of dep.get_variable('foo', ..) which in some
cases allows for further cleanups in future since we can
extract variables from pkg-config dependencies as well as
internal dependencies using this mechanism.

6e79932ad9 meson: List libraries and their corresponding gir definition
Introduces a `libraries` variable that contains all libraries in a
list with the following format:

``` meson
libraries = [
    [pkg_name, {
        'lib': library_object
        'gir': [ {full gir definition in a dict } ]
    ],
    ....
]
```

It therefore refactors the way we build the gir so that we can reuse the
same information to build them against 'gstreamer-full' in gst-build
when linking statically
