52706146f5 pluginfeature: Allow updating initial rank of plugin feature
Introducing "GST_PLUGIN_FEATURE_RANK" environment variable in order for users
to adjust rank of plugin(s) via environment.

A "feature" and "rank" key-value pair should be separable by ":",
and each key-value pair is recognized per "," delimiters. The rank
can be a numerical value or one of pre-defined rank values
such as "NONE", "MARGINAL", "SECONDARY", and "PRIMARY" in case-insensitive manner.

In addition to pre-defined { NONE, MARGINAL, SECONDARY, PRIMARY },
"MAX" can be passed to key value used to ensure having a higher rank
than other plugin features.

Example)
- GST_PLUGIN_FEATURE_RANK=qtdemux:256,h264parse:NONE
Set rank of qtdemux plugin to 256 (primary) and 0 (none) for h264parse.

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:

f62ee97592 buffer: store sequence number for metas
For metas where order might be significant if multiple metas are
attached to the same buffer, so store a sequence number with the
meta when adding it to the buffer. This allows users of the meta
to make sure metas are processed in the right order.

We need a 64-bit integer for the sequence number here in the API,
a 32-bit one might overflow too easily with high packet/buffer
rates. We could do it rtp-seqnum style of course, but that's a
bit of a pain.

We could also make it so that gst_buffer_add_meta() just keeps metas in
order or rely on the order we add the metas in, but that seems too
fragile overall, when buffers (incl. metas) get merged or split.

Also add a compare function for easier sorting.

We store the seqnum in the MetaItem struct here and not in the
GstMeta struct since there's no padding in the GstMeta struct.
We could add a private struct to GstMeta before the start of
GstMeta, but that's what MetaItem effectively is implementation-
wise. We can still change this later if we want, since it's all
private.

97aa82387f device-provider: Allow notifying application of device changes
Thi introduces new APIs to post a `DEVICE_CHANGED` message on the
bus so the application is notifies when a device is modified. For
example, if the "defaultness" of a device was changed or any property
that can be changed at any time. Atomically changing the device
object notifying that way allow us to abtract away the internal threads.

New APIS:
  - gst_message_new_device_changed
  - gst_message_parse_device_changed
  - gst_device_provider_device_changed

ca4b61c555 gstelementfactory: Add MEDIA_HARDWARE klass classifier
The Harware factory type classifier allows elements (decoders and encoders,
mostly) to advertize they rely on hardware devices to perform encoding or
decoding operations. This classifier can be used by applications to filter and
select only the elements that use hardware devices, for instance to ensure
zero-copy support is enabled for a specific pipeline.

05a3da347b protection: Add a new definition for unspecified system protection
In some cases the system protection ID is not present in the contents
or in their metadata.
This define is used to set the value of the "system_id" field in GstProtectionEvent,
with this value, the application will use an external information to choose which
protection system to use.

Example: The matroskademux uses this value in the case of encrypted WebM,
the application will choose the appropriate protection system based on the information
received through EME API.
