4375e998ee Fix casts in a bunch of inline functions to maintain correct const-ness
Make code including GStreamer headers compile with -Wcast-qual by
maintaining const-ness when casting. Also fix function signature of
gst_byte_writer_set_pos(): the byte writer should not be marked as
const.

f9204d5d70 build: use new AG_GST_PKG_CONFIG_PATH m4 macro from common
Sets up a GST_PKG_CONFIG_PATH variable for use in Makefile.am
(avoids trailing ':' in PKG_CONFIG_PATH used). A useful side
effect of this is also that the PKG_CONFIG_PATH environment
is now logged in the configure output.

f8abf35000 basetransform: recover from invalid downstream suggestions
When we are handling a buffer and need to allocate an output buffer, handle the
case when downstream suggests us a format that we can't convert the input buffer
to. In that case, check if there is another format available downstream instead
of failing.

29289ee79e basetransform fix for upstream caps-renegotiation
If initially pass-through caps are negotiated between a transform element's
sink and src pads, but then the downstream element returns different caps
on a buffer from pad_alloc(), basetransform gets stuck with proxy_alloc=TRUE
even though the upstream peer doesn't accept the caps, causing
gst_pad_peer_accept_caps() to be called on each buffer in _buffer_alloc():

    if (!gst_caps_is_equal (newcaps, caps)) {
      GST_DEBUG_OBJECT (trans, "caps are new");
      /* we have new caps, see if we can proxy downstream */
>>    if (gst_pad_peer_accept_caps (pad, newcaps)) {
        /* peer accepts the caps, return a buffer in this format */
        GST_DEBUG_OBJECT (trans, "peer accepted new caps");

which is taking ~40ms/frame.

This patch does two things.  (1) if the buffer returned from pad_alloc() has
new caps, trigger the decision whether to proxy the buffer-alloc to be
revisited, and (2) disable proxy if peer does not accept new caps.  (The first
part may not be strictly needed, but seemed like a good idea.)

Note that this issue would not arise except in case of downstream elements
who have on their template-caps, some that would be suitable for pass-through,
but at runtime pick more restrictive caps (for ex, after querying a driver for
what formats it actually supports).

574e6ab423 basetransform: Try suggesting caps on bad caps pad_alloc
When basetransform received an unsupported caps on pad_alloc
it just returned not-negotiated. This patch makes it query
the allowed caps between his sinkpad and upstream's srcpad
to find a caps to suggest.

This happens when dinamically switching pipeline elements
and upstream pad_allocs with the previous caps that was
being used.

6fb4cda8fb controller: Fix gst_interpolation_control_source_find_control_point_iter
The logic in that function is broken. Various NULL-checking bandaids for
guaranteed non-NULL variables didn't even help there.

This patch updates the function to check if a previous item exists
before fetching it instead of after. This makes all other tests
unnecessary.
In particular, it makes the check for an empty list unnecessary, because
for empty lists the only iter is the begin iter (and the end iter) and
so the new check catches that case.
