Adding strips or changing filepaths caused thatde movie files were loaded,
but memory was only released after new frame was rendered. Since FFmpeg
can take a lot of memory per strip, this can cause crash.
Free memory for each strip immediately after it is not needed after
these operations.

Property `speed_factor` was used before retiming. It was kept for
potential versioning code for complex speed animation, that was
possible with even older `pitch` property.
Strips, where `speed_factor` is set to static value are already
correctly converted.
Such versioning code would be quite complex, possibly slow and maybe
could corrupt files. This is due to multiple factors:
- Sound seeking was broken, so conversion would have to ignore all
keyframes before strip starts to map frames properly.
- Because some animation was effectively ignored, it may cause
inconsistencies when doing conversion.
- It would have to integrate value of `speed_factor` to map keyframes
to strip space, but the animation is not limited to strip length.
- For each keyframe where speed gradually changes, at least one smooth
speed transition would be required, but there would be discrepancies
that would have to be accounted for. With simpler strategy it is
likely, that extent of ramps would be limited and thus animation would
be quite different from original.
Because of these reasons, I think it is best to not convert
`speed_factor` animation.

The last good commit was 8474716abb.
After this commits from main were pushed to blender-v4.0-release. These are
being reverted.
Commits a4880576dc from to b26f176d1a that happend afterwards were meant for
4.0, and their contents is preserved.
Last key is drawn on the right edge of the strip, but that is end of
the frame, which it should be bound to. Because of this, drawing code
and operators must consider, that this key is always displaced.
This was not done in 86a0d0015a and caused issues like #113755 that was
fixed incorrectly.
In earlier design, retiming selection was managed outside of retiming
keys struct. This was changed to a flag of the retiming key struct.
Since moving of the transition deletes and re-creates keys, the
selection was lost. Selection is now re-established in
`seq_retiming_transition_offset()`.
After eda58d6419, multiply operation does not affect alpha channel, but
Some users do expect this feature present.
This adds option `multiply_alpha`, so that multiplication (in strip
color panel) will affect alpha channel as well.

Conversion from timeline frame to frame index was done by casting to
integer, which followed logic of ffmpeg seeking. However this is not
best approach in some cases - for example when FPS of scene and movie
differs by a very small amount. In this case the first frame could be
duplicated and all other frames will appear as offset by one frame.
In particular this may happen scene is set to 29.97 fps and movie is
encoded at 30000/1001 fps. A frame will still have to be duplicated, but
it should be frame where decimal of frame index crosses 0.5 to keep
audio and video in sync as best as possible.

Move the three current 'status variables' (stop, update and progress)
into a single 'WorkerStatus' struct. This is cleaner and will allow for
future workin this area without having to edit tens of 'startjob'
callbacks signatures all the time.
No functional change expected here.
Note: jobs' specific internal code has been modified as little as
possible, in many cases the job's own data still just store pointers to
these three values. Ideally in the future more refactor will be using a
single pointer to the shared `wmJobWorkerStatus` data instead.

Currently retiming is quite awkward, when you need to retime multiple
strips strips in sync. It is possible to use meta strips, but this is
still not great. This is resolved by implementing selection.
General changes:
Gizmos are removed, since they are designed to operate only on active
strip and don't support selection.
Transform operator code is implemented for retiming data, which allows
more sophisticated manipulation.
Instead of drawing marker-like symbols, keyframes are drawn to
represent retiming data. Retiming handles are now called keys. To have
consistent names, DNA structures have been renamed.
Retiming data is drawn on strip as overlay.
UI changes:
Retiming tool is removed. To edit retiming data, press Ctrl + R, select
a key and move it. When retiming is edited, retiming menu and
context menu shows more relevant features, like making transitions.
Strip and retiming key selection can not be combined. It is possible to
use box select operator to select keys, if any key is selected.
Otherwise strips are selected.
Adding retiming keys is possible with I shortcut or from menu.
Retiming keys are always drawn at strip left and right boundary. These
keys do not really exist until they are selected. This is to simplify
retiming of strips that are resized. These keys are called "fake keys"
in code.
API changes:
Functions, properties and types related to retiming handles are renamed
to retiming keys:
retiming_handle_add() -> retiming_key_add()
retiming_handle_move() -> retiming_key_move()
retiming_handle_remove() -> retiming_key_remove()
retiming_handles -> retiming_keys
RetimingHandle -> RetimingKey
Retiming editing "mode" is activated by setting `Sequence.show_retiming_keys`.

To reproduce build error, set `WITH_AUDASPACE` to `ON` in `blender_lite.cmake` and build using `make lite`.
The problem is that the function `AUD_Sound_equalize` is declared in `blender/extern/audaspace/bindings/C/AUD_Sound.h` within `WITH_CONVOLUTION` and not `WITH_AUDASPACE`.

This commit disambiguates the following messages:
- Sequencer effect strip types: use "Sequence" context in relevant
places, as that is already extracted as part of the
`sequencer_prop_effect_types` enum, and more specific.
- "Language" (a natural or programming language)
- "Flat" (gender)
- "Smooth" (action or amount -- very partial disambiguation for now
because this is all over the place)
It also extracts these messages:
- Newly created Freestyle data
- LineStyle
- LineSet
- Modifiers
- "Registering panel class:" error message from RNA registration
- "Node must be run as tool" error message from tool geometry nodes

The sound equalizer is using the Audaspace FFT Convolver.
The blender part creates an array of descriptions of power per "band"
and orders the creation of Equalizer (ISound) in the Audaspace.
Modifier can be created on sound strips. It lets you define
amplification or attenuation over frequency range from 30Hz to 20 kHz.
The power is limited to -30 db - 30 db. This is done using curve
mapping widget.

With such small proxy sizes (combined with a small blur radius), the
kernels `halfWidth` can get zero, which leads to a memory allocation of
same zero size and writing to that memory leads to overflow/crashes/can
only go downhill from there.
Now early out in such cases [which leads to
slightly different output -- well if the "buggy" output survives and
does not crash that is].
(alternatively we could just prevent the overflow and still let do
`RVBlurBitmap2_float` do stuff that it really shouldnt imo, see first version of the PR)

Previously `SEQ_modifier_list_copy` in append mode does not ensure
unique strip name, which will result in duplicated names in target
modifier list, then `strip_modifier_remove(name="something")` can remove
the wrong one later on. Now fixed using `BLI_uniquename`.

The `lib_link` callback cannot always be fully replaced/removed, as in
some case it is also doing some validation checks, or data editing based
on the result of lib_linking internal ID pointers.
The callback has been renamed for that purpose, from `read_lib` to
`read_after_liblink`. It is now called after all ID pointers have been
fully lib-linked for the current ID, but still before the call to
`do_versions_after_linking`.
This change should not have any behavioral effect. Although in theory
the side-effect of this commit (to split lib linking itself, and the
validation/further processing code) into two completely separated steps
could have some effects, in practice none are expected, and tests did
not show any changes in behavior either..
Part of implementing #105134: Removal of readfile's lib_link & expand code.
The `expand` callback is 'trivial' to replace, since it is only iterating
over ID pointers and calling a callback.
The only change in behavior here is that some pointers that were not
processed previously will now be.
In practice this is not expected to have any real effect (usually
the IDs used by these pointers would have been expanded through other
usages anyway). But it may solve a few corner cases, undocumented issues
though.

Factor of Color>Multiply should not have an effect on the alpha channel.
Alpha values can be adjusted separately by the factor associated to blend mode.
Factors below 1.0 reducing alpha would reduce color twice, while factors
above 1.0 would be clamped to 1.0.
- Removed ops on alpha channel in multiBuf()
- Removed adjustement of ibuf-planes since alpha channel is no longer
modified

This fixes a few related issues in VSE code:
* 'lib_link' code was doing 'read_data' tasks (like cleaning up internal
runtime data).
* Handling of `SEQ_TYPE_SOUND_HD` deprecated type of strips was
extremely confusing (versioning done partly in 'lib_link' code, partly
in some 2.50 do_version code).
* Still using deprecated `SEQ_TYPE_SOUND_HD` strip type outside of
versioning code.
* Missing proper usage of deprecated `SEQ_TYPE_SOUND_HD` type inside of
versioning code (!).
Note that the actual conversion from `SEQ_TYPE_SOUND_HD` to
`SEQ_TYPE_SOUND_RAM` is now done in the 'after setup' versioning
process, where it is somewhat safer to add IDs. This implies that
`SEQ_TYPE_SOUND_HD` must be taken into account throughout the whole
regular versioning process (before and after liblink).
Conversion logic itself has been moved to the VSE code.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
