9ebbce381a adaptivedemux: do not skip the first fragment
Avoid advancing fragment right after downloading the header. If it
is the header, by default, don't advance to the next fragment.

229a15b393 adaptivedemux: refactor chunk downloading flow
Add more power to the chunk_received function (renamed to data_received)
and also to the fragment_finish function.

The data_received function must parse/decrypt the data if necessary and
also push it using the new push_buffer function that is exposed now. The
default implementation gets data from the stream adapter (all available)
and pushes it.

The fragment_finish function must also advance the fragment. The default
implementation only advances the fragment.

This allows the subsegment handling in dashdemux to continuously download
the same file from the server instead of stopping at every subsegment
boundary and starting a new request

9336077057 adaptivedemux: fix multi-period playback
If we say it is the first segment after a new period it will resync
the segment.start value and all buffers will be late for the new period
we are trying to play. Otherwise we want to keep the segment.start with
the previous value to allow the running time to smoothly increase

989af902fe glmemory: use the correct size for the pbo
It was missing the GstVideoAlignment padding which could cause GL
errors related to overrunning the size of the pbo.

3a79bd91c7 adaptivedemux: prevent early EOS when switching at last fragment
Check if there is a next fragment before advancing to avoid causing
a bitrate switch (and maybe exposing new pads) only to push EOS.
This causes playback to stop with an error instead of properly
finishing with EOS message.

516f1ae0f4 adaptivedemux: add a special return to signal subsegment boundary
The subsegment boundary return tells the adaptivedemux that it can
try to switch to another representation as the stream is at a suitable
position for starting from another bitrate.

9b260d1ba5 adaptivedemux: Actually use the byte range for the fragment url
Otherwise we would always download the full fragment. This would
make handling subsegments in DASH impossible.

5c3a87c117 adaptivedemux: allow downloads of headers only
In order to get some subsegment information, subclasses might want
to download only the headers to have enough data (the index)
to decide where to start downloading from the subsegment.

5823f8b408 adaptivedemux: inform subclass when headers/index are being downloaded
This allows the subclasses to know if the chunks that are downloaded are
part of the header or of the index and will parse the parts that are
of their interest.

8fef381417 glmemory: remove spurious gst_video_info_align
That will be taken care of by the calling code (typically a bufferpool).
The GstVideoAlignment is purely informational to compute plane data sizes.

c73a5e0c54 h264parser: fix stack smashing
Ensure that we do not trust the bitstream when filling a table
with a fixed max size.
Additionally, the code was not quite matching what the spec says:
- a value of 3 broke from the loop before adding an entry
- an unhandled value did not add an entry
The reference algorithm does these things differently (7.3.3.1
in ITU-T Rec. H.264 (05/2003)).

This plays (apparently correctly) the original repro file, with
no stack smashing.

Based on a patch and bug report by André Draszik <git@andred.net>

fa5c433e7e gl/cocoa: Disable hack for NSApp iteration with a special #define
The hack causes deadlocks and other interesting problems and it really
can only be fixed properly inside GLib. We will include a patch for
GLib in our builds for now that handles this, and hopefully at some
point GLib will also merge a proper solution.

A proper solution would first require to refactor the polling in
GMainContext to only provide a single fd, e.g. via epoll/kqueue
or a thread like the one added by our patch. Then this single
fd could be retrieved from the GMainContext and directly integrated
into a NSRunLoop.

4da01dadcc aggregator: check if pads are ready more efficiently
No need to use an iterator for this which creates a temporary
structure every time and also involves taking and releasing the
object lock many times in the course of iterating. Not to mention
all that GList handling in gst_aggregator_iterate_sinkpads().
