x264enc: Reduce log spam about bit depth support

mpeg2dec: drop B-frame on open gop

Enhance open gop detection to drop B-frame which are invalid
before the first reference frame.

In stream such
gst-integration-testsuites/medias/defaults/mxf/op2b-mpeg2-wave_hd.mxf,
the two first frames must be dropped as we detect an open GOP situation
but in another media, such as http://col.la/1920X1080IXDCAMEX5MIN, the
first frames should not be dropped as we are in a closed GOP situation.

Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-ugly/-/merge_requests/84>

Use g_memdup2() where available and add fallback for older GLib versions

- x264 encoder bitrate profile manager: alloc size is based
  on existing allocation
- asfdemux: change length var to 64-bit and check for G_MAXUINT
- realmedia: opaque_data_len is read from 32 bits and then
  only subtracted upon.

g_memdup() is deprecated since GLib 2.68 and we want to avoid
deprecation warnings with recent versions of GLib.

tests: fix meson test env setup to make sure we use the right gst-plugin-scanner

If core is built as a subproject (e.g. as in gst-build), make sure to use
the gst-plugin-scanner from the built subproject. Without this, gstreamer
might accidentally use the gst-plugin-scanner from the install prefix if
that exists, which in turn might drag in gst library versions we didn't
mean to drag in. Those gst library versions might then be older than
what our current build needs, and might cause our newly-built plugins
to get blacklisted in the test registry because they rely on a symbol
that the wrongly-pulled in gst lib doesn't have.

This should fix running of unit tests in gst-build when invoking
meson test or ninja test from outside the devenv for the case where
there is an older or different-version gst-plugin-scanner installed
in the install prefix.

In case no gst-plugin-scanner is installed in the install prefix, this
will fix "GStreamer-WARNING: External plugin loader failed. This most
likely means that the plugin loader helper binary was not found or
could not be run. You might need to set the GST_PLUGIN_SCANNER
environment variable if your setup is unusual." warnings when running
the unit tests.

In the case where we find GStreamer core via pkg-config we use
a newly-added pkg-config var "pluginscannerdir" to get the right
directory. This has the benefit of working transparently for both
installed and uninstalled pkg-config files/setups.

Cerbero and it doesn't affect older versions so it should be ok.

asfdemux: Always re-initialize metadata and global_metadata

When transitioning from the PAUSED state, to the READY state, and back,
metadata and global_metadata are left uninitialized, unlike when the
demxuer transitions from NULL to READY, then to PAUSED.  I have found
this to cause a segmentation fault when fields in these structures are

x264enc: Fix 'ref' property range and default

The --ref option indicate the size of the DPB, hence should be in the range of

change isn't a behaviour change since we don't enforce the reported default.

a52dec: Mark as converter
