multimedia/gstreamer1: Update to 1.24.8

Mk/Uses/gstreamer.mk:
- Sort, fix whitespace issues and typos
- Promote several common variables to improve maintainer QOL
*   There's now no need to set manually set PORTVERSION nor
    SOVERSION in several Makefiles
*   This will help to prevent not updating some components
*   A note has been added, however, to remind maintainers
    to remake distinfo for certain ports
- Improve documentation

multimedia/gstreamer1-plugins-webrtc:
- New port split from multimedia/gstreamer1-plugins-bad

Switch Opus to USES=libtool.
Bump dependent ports. [1]

Update gstreamer 1.0 ports to version 1.2.4.

When linking a library libA with a library libB using libtool, if libB.la
exists, libtool will add all libraries libB.la refers to (dependency_libs
field) to the linker command line and store them in the dependency_libs
field of libA.la.  So everything that subsequently links with libA will also
link to these extra libraries.  This causes too much overlinking.

This commit modifies Mk/Uses/libtool.mk so it empties the dependency_libs
field in .la libraries during staging.  However, because .la libraries have
very limited use when dependency_libs is empty it makes sense to completely
remove them during staging.

So with this commit USES=libtool is modified to remove .la libraries and a
new form (USES=libtool:keepla) is introduced in case they need to be kept
(dependency_libs is still emptied).

Update to 1.2.2.

Remove vaapi from plugin list in bsd.gstreamer.mk it accidently snuck in.

Changelog:

Update opus to 1.1, which includes:
* new analysis code and tuning that significantly improves encoding
  quality, especially for variable-bitrate (VBR),
* automatic detection of speech or music to decide which encoding
  mode to use,
* surround with good quality at 128 kbps for 5.1 and usable down
  to 48 kbps,
* and speed improvements on all architectures.

Chase shared library bump.

Add Gstreamer 1.0.7. This is the new stable version of the
Gstreamer multimedia framework.

Use the USE_GSTREAMER1 macro to select Gstreamer 1.0 plugins. A new chapter
for the porters handbook about gstreamer is a work in progress.

X related plugins are now stand alone. The gio plugin is now part of the
gstreamer1-plugins port and the oss plugins are now part of the
gstreamer1-plugins-good port.

Note that the pulseaudio plugin is missing because it needs a newer version
of pulseaudio. Also there are still a number of plugins from -bad which
haven't been ported to the 1.0 API yet.
