5ccc8432e0 audiodecoder: fix tag handling
Before we just merged everything in pretty much random ways
ad-hoc instead of keeping state properly. In 0.10 that was
how it worked, but in 1.x the tag events sent should always
reflect the latest state and replace any previous tags.

So save the upstream (stream) tags, and save the tags set
by the decoder subclass with merge mode, and then update
the merged tags whenever either of those two changes.

This slightly changes the behaviour of gst_audio_decoder_merge_tags()
in case it is called multiple times, since now any call replaces
the previously-set tags. However, it leads to much more predictable
outcomes, and also we are not aware of any subclass which sets this
multiple times and expects all the tags set to be merged.

If more complex tag merging scenarios are required, we'll have
to add a new vfunc for that or the subclass has to intercept
the upstream tags itself and send merged tags itself.

5a0bee3f13 audioencoder: add src and sink query methods
Allows subclasses to do their own handling of GstQuery and still
chain up to the parent class to handle the ones that they don't want
to handle

Apparently I forgot how gobject works, there is no need to expose
it directly as one can call it from the parent_class pointer

Use the object lock to protect the internal segment when updating

one sits and waits in the queue.

6ddab6918d basedepayloader: Don't re-timestamp with running-time
There was a confusion, six depayloaders where passing through the
timestamp while the base class was re-timestamping to running
time. This inconstancy has been unnoticed has in most use cases
the incoming segment is [0, inifnity] in which case timestamps are
the same as running time. With DTS/PTS shifting added (to avoid
negative values) and pcapparse sending a different segment this
started being an issue.

Add process_rtp_packet() vfunc that works just like the
existing process() vfunc only that it takes the GstRTPBuffer
that the base class has already mapped (with MAP_READ),
which means that the subclass doesn't have to map it again,
which allows more performant processing of input buffers
for most RTP depayloaders.

This minor update should workaround a build system bug. While the
makefile has been updated to generate more enum type, there is nothing

produced again. This minor doc fix should ensure no one get a build with
missing symbols.

190c7f1928 GstVideoScaler: Initialised scaling functions to get rid of compiler messages
E.g.

video-scaler.c: In function 'gst_video_scaler_horizontal':
video-scaler.c:1332:3: error: 'func' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   func (scale, src, dest, dest_offset, width, n_elems);
   ^

video-scaler.c: In function 'gst_video_scaler_vertical':
video-scaler.c:1373:3: error: 'func' may be used uninitialized in this function [-Werror=maybe-uninitialized]
   func (scale, src_lines, dest, dest_offset, width, n_elems);
   ^

GCC's analyses seem to be correct, for the simple fact that if you pass
get_functions a known format, but no hscale or vscale, it'll return
True without having done anything.
Some callers check for the scale values to be not NULL, but then
hscale->resampler.max_taps could return 0.
A different approach to the one presented in this patch is to check
for those max_taps, too, before calling get_functions.

1586981b1b rtcpbuffer: Fix validation of packets with padding
The padding (if any) is included in the length of the last packet, see
RFC 3550.

Section 6.4.1:
   padding (P): 1 bit
      If the padding bit is set, this individual RTCP packet contains
      some additional padding octets at the end which are not part of
      the control information but are included in the length field. The
      last octet of the padding is a count of how many padding octets
      should be ignored, including itself (it will be a multiple of
      four).

Section A.2:
   *  The padding bit (P) should be zero for the first packet of a
      compound RTCP packet because padding should only be applied, if it
      is needed, to the last packet.

   *  The length fields of the individual RTCP packets must add up to
      the overall length of the compound RTCP packet as received.
