581c4297d0 dataqueue: add gst_data_queue_push_force
Adds a variant of the _push function that doesn't check the queue limits
before adding the new item. It is useful when pushing an element to the
queue shouldn't lock the thread.

One particular scenario is when the queue is used to serialize buffers
and events that are going to be pushed from another thread. The
dataqueue should have a limit on the amount of buffers to be stored to
avoid large memory consumption, but events can be considered to have
negligible impact on memory compared to buffers. So it is useful to be
used to push items into the queue that contain events, even though the
queue is already full, it shouldn't matter inserting an item that has
no significative size.

This scenario happens on adaptive elements (dashdemux / mssdemux) as
there is a single download thread fetching buffers and putting into the
dataqueues for the streams. This same download thread can als generate
events in some situations as caps changes, eos or a internal control
events. There can be a deadlock at preroll if the first buffer fetched
is large enough to fill the dataqueue and the download thread and the
next iteration of the download thread decides to push an event to this
same dataqueue before fetching buffers to other streams, if this push
locks, the pipeline will be stuck in preroll as no more buffers will be
downloaded.
There is a somewhat common practice in dash streams to have a single
very large buffer for audio and one for video, so this will always
happen as the download thread will have to push an EOS right after
fetching the first buffer for any stream.

API: gst_data_queue_push_force

75d9454bf4 gst: Add new group-id field to the stream-start event
All streams that have the same group id are supposed to be played
together, i.e. all streams inside a container file should have the
same group id but different stream ids. The group id should change
each time the stream is started, resulting in different group ids
each time a file is played for example.

Added a new function gst_check_setup_events_with_stream_id(), since
gst_check_setup_events() does not work with multiple pads.

The check is done using curl (if available). It lists the curl exit code + http
status code (for those > 399) together with the use of the url in the code. The
check is not fatal.

bd48ba333d structure: Add gst_structure_new_from_string()
Convenience API for bindings, gst_structure_from_string() returns
a tuple (structure, end_ptr) in bindings and is unintuitive to use
because of that.

54c678a21e query: new _BANDWIDTH_LIMITED flag
Source elements with limited bandwidth capabilities and supporting
buffering for downstream elements should set this flag when answering
a scheduling query. This is useful for the on-disk buffering scenario
of uridecodebin to avoid checking the URI protocol against a list of
hardcoded protocols.

65c650d7d4 capsfeatures: Add GST_CAPS_FEATURES_ANY
This is equal to any other caps features but results in unfixed caps. It
would be used by elements that only look at the buffer metadata or are
currently working in passthrough mode, and as such don't care about any
specific features.

7477b25df5 caps: Add new data type for handling caps features to the caps
These are meant to specify features in caps that are required
for a specific structure, for example a specific memory type
or meta.

Semantically they could be though of as an extension of the media
type name of the structures and are handled exactly like that.
