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.

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.
And use it for the fraction comparisons in gstvalue.c instead
of using comparisons by first converting the fractions to double.
Should fix bug #628174.
API: gst_util_fraction_compare()
Instead return after every iteration, which makes sure that the
stream lock is released for a short time after every iteration,
task state changes are checked, etc and this allows the task
to be stopped properly.
The problem with both macros is, that they suggest something that isn't true.
If GST_FLOW_IS_FATAL is true, there could still be a problem for many elements
and they should stop what they're currently doing and return that value
upstream (e.g. not-linked in a parser). If GST_FLOW_IS_SUCCESS is false, it
could still be that this is "ok" for the element (e.g. not-linked for a demuxer
on a few of its pads but not all).
It's better to not have these "convenience" macros but instead let people
*think* about the handling of different flow returns, that makes sense for
their element. And we should document the expected handling of flow returns for
different classes of elements in the plugin writer's guide.
Fixes bug #628014.
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.
Fixes#621332 and see also #614296
Adds GST_TAG_APPLICATION_DATA for representing arbitrary private
data that applications might want to store into tags. Exif/id3,
for example, have tags for this.
API: GST_TAG_APPLICATION_DATA
Fixes#626651
When there is a sink inside a bin, the SINK flag is set on the bin. When we are
trying to iterate the source elements, also include the bins with the SINK flag
because they could also contain source elements, in which case they are also a
source.
This solves the case where sending an EOS to a pipeline didn't get dispatched to
all source elements.
See #625597
gst_element_link_many does some magic and creates ghostpads
if needed, but it didn't set the newly created ghostpad to
active if needed. This patch fixes it.

- Set reading_pos correctly in _create_read ()
- Seek to data if it is further than QUEUE_MAX_BYTES (queue) -
cur_level.bytes away. This should avoid a situation where the ring
buffer is full but the data offset from which we shall read is not in
the ring buffer.
- Only update the max_reading_pos to a lower value to protect data when
necessary
- Always signal an ADD in _locked_enqueue () so that an EOS unlocks the
reader
- More useful debug output
update_buffering () needs to be called every time we write to the ring
buffer so that applications don't get stuck waiting for a 100% buffered
message while queue2 is waiting for space
_create_write () must only be called for temp file/ring buffer cases
