If an input is malformed (only produces cea608 field 1 cc_data) then
when in passthrough we would effectively be dropping every second cea608
on output as we would not store any unused cea608 data.
Fix by having all code paths go through the framerate conversion code
which will store and retrieve any relevant data across buffers.

When a tile format is padded and imported as DMABuf, the stride
contains the information about the actual width and height in
number of tiles. This information is needed by the detiling shader
in order accuratly calculate the location of pixels. To fix that,
we also copy the offset and strides into the otuput format and
the converter will ensure that the shader is recompiled whenever
the stride changes.
This fixes video corruptions observed when decoding on MT8195
with videos that aren't not aligned to 64bytes in width.

1. Removes the verification if the internal encoder is not opened
yet to allow the property setting.
2. And toggles on the base class' reconf flag for each property
variable that can be modified at run time.
3. Mark those modifiable properties as mutable while playing.
Currently the run-time modifiable properties are:
qpi, qpp, qpb, bitrate, target percentage, target usage and rate control
Other properties can be enabled too, but they need testing.

Adds an internal function reset() which drains the internal queues and
calls the reconfig() vmethod.
This reset() method is called inconditionally at set_format() and in
handle_frame() if the instance's reconf flag is enabled.

If parameters remain similar enough to avoid either encoder reopening
or downstream renegotiation, avoid it.
This is going to be useful for dynamic parameters setting.
To check if the stream parameters changed, so the internal encoder has
to be closed and opened again, are required two steps:
1. If input caps, profile, chroma or rate control mode have changed.
2. If any of the calculated variables and element properties have
changed.
Later on, only if the output caps also changed, the pipeline
is renegotiated.

This method will return the caps configured in the reconstruct buffer
pool, and its maxium number of buffers to allocate.
The caps are needed later to know if the internal encoder has to be
reopened if the stream properties change.

This adds a new boolean property `auto-reconnect`, defaulting to `true`.
Setting it to `false` makes the elements (in caller mode) immediately
report an error to the application instead of trying to reconnect.

Use gst_debug_set_threshold_from_string's new reset behavior to undo
GST_DEBUG and ensure the logging tests have a known configuration.
`gst_debug_set_threshold_from_string ("LOG", TRUE)` has the same effect
as `gst_debug_set_threshold_from_string ("", TRUE)` followed by
`gst_debug_set_default_threshold (GST_LEVEL_LOG)`.
Don't bother remembering the default log level set when the test
started. It will get reset by the next test, anyway.

TLDR: Make `gst_set_threshold_from_string ("", TRUE)` reset *all*
threshold settings, including those set by previous invocations of
`gst_debug_set_threshold_from_string`.
The docs say:
@reset: %TRUE to clear all previously-set debug levels before setting
new thresholds
What actually happens is it sets the default threshold to `ERROR`,
leaves the patterns in place and calls
`gst_debug_category_reset_threshold` on each category.
In effect, any category that is matched by a pattern gets reset to that
threshold if the app changed it by directly invoking
`gst_debug_category_set_threshold`. All other categories are reset to
`ERROR`.
In my opinion this parameter currently has little value, as the same
effect can be achieved by including `ERROR` (without a pattern) in the
string, as in `"foo*:WARNING,*bar:INFO,ERROR"`.
What I actually expect it to do is reset *all* threshold settings,
including those set by previous invocations of
`gst_debug_set_threshold_from_string`, starting off with a clean slate
for the patterns provided with the call.
Otherwise there is no API to do this, besides:
- Painfully removing patterns one-by-one via
`gst_debug_unset_threshold_for_name` *if* you know what the patterns
are.
- Adding a `*:FOO` pattern to affect all categories, which makes the
default threshold useless and practically leaks all the old
patterns.
In my opinion this also makes it fit better into the layers of threshold
config, which is:
1. Temporary:
- `gst_debug_category_set_threshold`
- `gst_debug_category_reset_threshold`
2. Patterns:
- `gst_debug_set_threshold_for_name`
- `gst_debug_unset_threshold_for_name`
- `gst_debug_set_threshold_from_string`
- `GST_DEBUG`
3. Default:
- `gst_debug_set_default_threshold`
