We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.
It is the only thing gst_pb_utils_init() does and it could be
automatically called from the places in pbutils it is needed.
After 1.14 we should deprecate gst_pb_utils_init().

There is a race going on somewhere when we attempt to remove elements
*while* the parent container is switching to PLAYING.
In order to avoid this issue with discoverer, make sure we never
remove elements while switching to PLAYING.
This would result in a lot of warnings regarding elements not being
in NULL state when removed, or even leaked elements.
Instead make sure we take the lock and check whether we are processing
or not before allocating or adding anything to the pipeline
And monitor no_more_pads.
With live sources such as rtsp, uridecodebin only creates its
child decodebins between PAUSED and PLAYING.
This means that the ASYNC_DONE it posts when getting NO_PREROLL
in its change_state method gets immediately propagated by the
GstBin parent class, as opposed to a situation where a
decodebin has been added to it already, and has posted ASYNC_START.
The proposed solution, instead of simply waiting for ASYNC_DONE,
and finishing prematurely in that case, waits for three conditions
to be true:
* the uridecodebin needs to have emitted no_more_pads
* its current state must be PAUSED if not live, PLAYING otherwise
* There must be no "pending subtitle pads", ie pads where we haven't
received tags yet.
All these conditions are checked in the message handler, as we
post custom messages on it when we get subtitle tags or no_more_pads.

Child streams could have more accurate width/height or various other
information added. If they have the same name, they are likely to be the
same streams.

The parser might do some conversion on a stream but the stream keeps
being the same, and we need to make sure GstDiscoverer detects it is the
case.

It is often usefull to make sure that you get a full copy of a profile.
For example you want to let the user modify it in the user interface
but still keep an unchanged version for later use.
API:
gst_encoding_profile_copy
encoding-profile.c: In function ‘get_profile_format_from_possible_factory_name’:

cc1: all warnings being treated as errors
Instead of enforcing the user to know and understand caps to describe
the encoding format, let him use element factory names directly.
This also makes it possible to ensure that a specific encodore/muxer
is used instead of letting the ranking system do it.
It is now possible to describe an encoding format simply specifying:
matroskamux:x264enc:vobisenc
Factor out functions in the parsing, cleaning up the whole thing.
Update documentation.
We used to only care about the name of the files even if the name
is defined in the encoding target serialized file.
That commit also allows user to define several names for a single
target file (using a ';' between the names) which allows us to have
a target for youtube that is called 'youtube;yt' or a target for
'ogg;ogv;oga' file extension.
