588ac0ae6f baseaudiosink: don't allow aligning behind the read-segment
Given a large enough drift-tolerance, one could end up in a situation
where one would keep aligning the written buffers behind the current
read-segment position. The result for the reader would be complete
silence, possible preceded by very choppy audio.

By checking the available headroom, one can determine if there is
room to do alignment, or if one should resort to a resync instead to get
the pointers back on track.

Also refactor the alignment-logic out of the render function for cleaner
code.

57ff12bb0d vorbistag: Add support for METADATA_BLOCK_PICTURE tags
This is the official, standardized way of embedding pictures
inside vorbiscomments now. Parsing code taken from flacparse
and slightly changed.

Fixes bug #635669.

Instead of using the GLib base64 decoding functions manually to
do inplace base64 decoding. This makes the code easier to understand.

e73f293ee5 baseaudiosink: arrange for running clock when rendering eos
Commit ba2e500bd9 ensured to provide
a running clock when EOS had finished rendering.  However,
other measures are needed (and were in place before) to ensure a
running clock when EOS still needs rendering (i.e. waiting).

So, specifically, re-introduce eos_rendering removed in aforementioned commit,
this time as a public variable so subclasses can be aware of the situation.

Fixes (part of) #645961.

45b6bda76c libs: make sure gobject-introspection scanner calls gst_init()
Cherry-picked from 0.11, since it's the right thing to do (we
now silently rely on various _get_type() working without
gst_init() having been called).

34ba387d0b tagxmpwriter: Adds a new GstTagXmpWriter interface
The GstTagXmpWriter interface is to be implemented on elements that
provide xmp serialization. It allows users to select which
xmp schemas should be used on serialization.

API: GstTagXmpWriter

78e8b33c38 video: Getting component offsets without dimensions is fine if it is not YUV
This fixes a regression that an assertion would happen if
gst_video_get_component_offset would be called with width or
height as 0.

Calling it with 0 is fine if the format isn't yuv and this
was already being used in some other places of video.c

9ffb8859d7 discoverer: Don't wait for subtitle streams to preroll
Subtitle streams being parse can cause the pipeline to wait indefinitely
to PREROLL. This makes subtitle streams got to PAUSED even if no data is
available. This should not be a cause for concern as we don't expect to
get much data for subtitle streams other than language tags from the
container.

6ac2e5d384 discoverer: Drop new stream tags once preroll is done
This makes sure we do not touch the stream taglist once the pipeline has
been prerolled. Adding of stream tags happens in the pad event probe
which runs in a different thread from discoverer stream processing, so
modifying the tag list while discoverer might be processing it can
sometimes cause a crash.
