7a207da733 gstevent: Add function for checking event name by GQuark
Avoids doing string<=>quark conversions in the sticky event handling path.

1b2f968efc event/message: Don't allow setting invalid group ids
They are optional on STREAM_START messages/events but if available
should have at least a valid value.

For STREAM_GROUP_DONE events don't allow creating it with an invalid
group id as this does not make any sense.

be3c4d00cf event: Add new GST_EVENT_INSTANT_RATE_CHANGE and GST_SEEK_FLAGS_INSTANT_RATE_CHANGE
A seek with that flag set must be non-flushing, not change the playback
direction and start/stop position. A seek handler will then send the new
GST_EVENT_INSTANT_RATE_CHANGE event downstream for downstream elements
to immediately apply the new playback rate before the new in-band segment
event arrives.

b99bca2790 event: fix seek event creation
Creating seek events segfaults on 32-bit ARM since commit 2fa15d5371
('event: add new seek parameter, "trickmode-interval"'), which missed
casting the trickmode-interval initializer in the variable argument list
to guint64.

2fa15d5371 event: add new seek parameter, "trickmode-interval"
When performing a key unit trickmode seek, it may be useful to
specify a minimum interval between the output frames, either
in very high rate cases, or as a protection against streams
that may contain an overly large amount of key frames.

One use case is ONVIF Section 6.5.3:

8f496b7392 event: Unset SNAP flags when creating a new seek event without KEY_UNIT flag
The SNAP flags only make sense in combination with the KEY_UNIT flag,
and without they expose all kinds of unexpected behaviour in various
elements that don't expect this from happening.

Also warn if this ever happens.

c0c9a531ef event: Don't allow invalid SELECT_STREAMS event creation
Asking to select no streams makes no sense and can create various
issues.

If one doesn't one any stream it should deactivate (or not use) the
element in question.

9fd2101b36 events: Implement the stream-group-done event
A new event which precedes EOS in situations where we
need downstream to unblock any pads waiting on a stream
before we can send EOS. E.g, decodebin draining a chain
so it can switch pads.

a3513d6e97 event: Make sure that timestamp + diff in QoS events is never smaller than 0
When a running-time-offset is stored in the event, it could become smaller
than 0 although the event is otherwise correct. This can happen when pad
offsets are used.

To prevent this, we set the timestamp to -diff, so that in the end the sum of
both is exactly 0.

0f36b16a29 event: add new GST_EVENT_PROTECTION
In order for a decrypter element to decrypt media protected using a
specific protection system, it first needs all the protection system
specific  information necessary (E.g. information on how to acquire
the decryption keys) for that stream.

The GST_EVENT_PROTECTION defined in this commit enables this information
to be passed from elements that extract it (e.g. qtdemux, dashdemux) to
elements that use it (E.g. a decrypter element).

API: GST_EVENT_PROTECTION
API: gst_event_new_protection()
API: gst_event_parse_protection()

d445027ec1 event: Add running-time-offset field to all events

offset set via gst_pad_set_offset() will get their offset
adjusted according to the pad's offset.

If the event contains any information that related to the
running time, this information will need to be updated
before usage with this offset.

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.
