Adds a simple 4x4 affine transformations meta for passing arbitrary
transformations on buffers.

Based on patch by Matthieu Bouron

https://bugzilla.gnome.org/show_bug.cgi?id=731791

Add GstVideoChroma, GstVideoDither, GstVideoScaler and friends to the docs.

Remove and clean up a few obsolete/deleted refs and typos

Add sections docs for audiometa. Fix sections docs for audiochannels. Remove old
mixerutil section.

Remove includes and functions that don't exist any longer,
add new ones instead.

The navigation interface is now in the video library.

Another mini-lib down, to make space for new mini libs.

Remove bogus copyright line while at it.

There's no code whatsoever that uses these macros. If anyone
ever feels the need to resurrect them, we should add them to
gstutils.h in core or libgstaudio or so.

This is useful and in most cases someone had put arbitrary markup into the docs,
misspelled xref'ed symbols, forgot to add stuff to the docs etc..

And remove deprecated methods, and fix up some cruft.

Add missing section. Add new section to main-sgml. Add missing function.

This can be used by sinks to take compressed formats, correctly payload
these in IEC 61937 frames and feed these to sinks that support
passthrough output over IEC 60958 (S/PDIF) or, in the case of MP3, over
Bluetooth.

Initial implementation includes AC3, E-AC3, MPEG-1, MPEG-2 (non-AAC),
and DTS (type-I/II/II) payloading. More formats can be added as needed.

Fixes #625944

Add minimal docs for GstRTSPExtension so people know it exists.

XMP metadata can be embedded in many media container formats. Implement own
parser and formatter that can be used to convert between an xpacket and a
GstTagList. Add unit tests.

Correct name of included files. Remove files that are not used anymore. Add many
new api entries to their sections.

Add some utility functions for language tags and ISO-639
codes. These are useful for both GUIs and elements. The
iso-codes package is used for language name translations
if available.
