Refactor the videorate element to properly separate upstream and downstream
time domains when the `rate` property is set.
The previous implementation had issues with time domain conversions when
changing rates, especially during seeks after which we were basically confusing
input and output timestamps.
This also fixes rate changes as we are now tracking the wanted input timestamps
and not confusing them with the output, so this way we do not drop buffers when
the rate is changed while playing, meaning that the related tests have been
fixed

When the dots tracer is detected among active tracers, switch from
SHOW_ALL to SHOW_FULL_PARAMS to prevent parameter ellipsization.
The dots tracer is designed to work with gst-dots-viewer which can
handle long parameter values, so we preserve the full text in dot files.
This improves the viewing experience when using the dots tracer with
the gst-dots-viewer tool.

This checks if a tracer has registered to any hook after
initialization and automatically registers it to the "none" hook if not
so the lifetime of those tracer is the same as tracer who registers to hooks.
For example the `dots` tracer was being freed right after initialization
which was unexpected.

When GStreamer pipeline graphs contain references to other pipeline dot files,
users should be able to navigate between related pipeline views by clicking
on these references. This enables exploring complex pipeline hierarchies
where one pipeline references sub-pipelines.
The implementation detects text elements containing pipeline-dot references,
styles them as web links, and handles click events to navigate to the
referenced pipeline while preserving existing text selection and drag
functionality for other elements.

Enable text selection on SVG text elements by changing CSS user-select
properties from 'none' to 'text' and cursor from 'default' to 'text'.
Add JavaScript event handling to intercept mousedown events on text
elements, preventing dragscroll interference while allowing normal text
selection. This preserves the existing drag-to-pan functionality for
non-text areas while making text elements selectable and copyable.

With video_maintenance1 extension is possible to create images independent of a
the video profile list, under that image will be processed.
With that extension is possible to share the same image for dynamic transcoding.

Change the logic to skip only devices which have "Input" as their IOID. The ALSA
Input/Output identifier (IOID) it may be either "Input", "Output", or NULL; with
the latter meaning that the device supports both input and output.

This was broken in b29262e662b86cd76225894f7504ee505125fa49.
The `gst_util_uint64_scale` emitted a critical warning and returned
`GST_CLOCK_TIME_NONE`, so beyond removing the warning this fix does not
change behavior.

This patch fixes this ill-usage of Vulkan API, by removing the feature enabling
of sampler ycbcr conversion, since it was promoted since Vulkan 1.1, and in
GStreamer is only used in Vulkan Video operations, which are only enabled in
Vulkan 1.3+.
Also, these features detection and enabling were moved to a function called when
filling the physical device data, in order to check the API version of the
device driver before adding the enabling of the feature.
Finally, the getters were adapted to use the version feature structure if the
device driver version matches.

Pushing the buffer via gst_pad_push () in transform_ip () function
causes downstream elements to process the buffer with a reference
count > 1. This leads to performance issue if there are downstream
elements which modify the buffer memory.
However, in drop-only mode this reference is not required.
So, let GstBaseTransform push the buffer in drop-only mode.

Don't reuse the same offset and size variables when reading
the byterange out of a MAP directive, as it can overwrite
values from a pending BYTERANGE directive for the next
fragment URI.
Fixes problems where the EXT-X-MAP directive has been written
into the playlist between an EXT-X-BYTERANGE and the fragment
URI it applies to.
