The GPL3 license header was copy'n'pasted from a
neighbouring source file by mistake, the original
code was not GPL3 licensed, but fell under the
default GStreamer license, which is LGPLv2+.

Otherwise interesting things will happen in Cocoa applications, like
infinite event loops that block the NSApplication loop forever.
This was only needed for GNUStep and thus can safely be removed now.
Until gcc and GNUStep properly support Objective-C blocks and other
"new" features of Objective-C we can't properly support them without
making the code much more ugly.

Otherwise e.g. videotestsrc ! openh264enc ! ... will drop every second frame
because otherwise the target bitrate can't be reached without loosing too
much quality.
Read PNG data chunk in one go by letting the parser
base class know the size we need, so that it doesn't
drip-feed us small chunks of data (causing a lot of
reallocs and memcpy in the process) until we have
everything.
Improves parsing performance of very large PNG files
(65MB) from ~13 seconds to a couple of millisecs.

Serves no purpose, is not even hooked up to the
build system, has hard coded file names and paths,
and can easily be replaced with a gst-launch line.

We will run into an assertion in set_caps() if we try to change
caps while the source is already running. Don't try to find new
caps in GstBaseSrc::negotiate() to prevent caps changes.
This commit add an helper to convert a frame to frame-layer format and
use it to implement these two stream-format conversion:
- asf --> sequence-layer-frame-layer
- asf --> frame-layer
In simple/main profile, we basically have a raw frame, so building a
frame layer isn't too complicated. But in advanced profile, the first
frame-layer should contain sequence-header, entrypoint, and frame and
each keyframe should contain entrypoint, so we have to handle these
carefully.

Add an helper to check that output stream-format is coherent with
profile and header-format. It also check if we know how to do the
conversion if the input stream-format differs from selected
output-format.
So, in case output stream-format is not allowed, it will now fail at
negotiation rather than in pre_push_frame.

This commit introduces an helper to convert an ASF frame to BDUs format with
startcodes and use this helper to implements following stream-format
conversions:
- asf --> bdu
- asf --> sequence-layer-bdu
- asf --> sequence-layer-raw-frame
https://bugzilla.gnome.org/show_bug.cgi?id=738526
It add the support of following stream-format conversion:
- bdu --> sequence-layer-bdu
- bdu-frame --> sequence-layer-bdu-frame
- frame-layer --> sequence-layer-frame-layer
For these conversion, the only requirements is to push a sequence-layer
buffer prior to data.
https://bugzilla.gnome.org/show_bug.cgi?id=738526
It prepares the template for stream-format conversion and it implements
the following conversion:
- sequence-layer-bdu --> bdu
- sequence-layer-bdu-frame --> bdu-frame
- sequence-layer-frame-layer --> frame-layer
Work is done in the pre_push_frame() method.

It's architecture dependent and should not be placed into the include
directory as the assumption is that all those headers are architecture
independent.
