Fix #29295: Problem with Alpha Channel video in Sequencer and textures

Bug was caused by workaround for old versions of FFmpeg which aren't supported
anymore due to pts stuff.

Removing workarounds for alpha channels.

Fix compilation error with oceansim disabled

Various typo cleanups, remove unnecessary code etc, found during recent work and separated to a cleanup change

Improve checking for getting layer "n" of a layer type and skip zero-length allocations for Bmesh layers

Muting node patch: first part

This allows node type init code to have access to the nodetree type object (needed to allow generic muting node initialization). Huge and boring edits...

== Sequencer / FFMPEG ==

This fixed two issues:

* RAW DV-seeking has to be done using DTS. Sounds silly, but ffmpeg
tracks internal state in RAW DV format decoder and runs mad, if
we seek by byte. Don't know, why I haven't noticed that, when I
added it.

* real fix(tm) for #29295
problem was: we did AVFrame read ahead, and the pattern
read_frame -> decode -> read_frame -> do color conversion of first frame
works everywhere but RAW RGB-files which do some pointer shuffling
within ffmpeg to save a memcpy...

I removed read ahead completely, since it didn't work like originally
intented. Might come back later, but the original purpose (making
resyncing easier if we are completely lost in stream) it never
fullfilled.

More UI messages fixes and tweaks (found while translating in french).

share code for fluidsim, ocean & dynamic paint file paths.
- use BLI_join_dirfile for joining all paths (no need to ensure slash is appended).
- paths from linked library files now supported.

* UI fix for recent Ocean Foam change, makes it a bit more compact.

UI: fix issue with part of panels going offscreen after recent commit.

The code here was tricky, with ED_region_panels trying to match the complex
logic in uiAlignPanelStep, now refactored the code so it's avoided.

Option to rename the vertex color data layer used by Ocean modifier for foam. The modifier outputs foam values to both textures and a (temporary) vertex data layer. This layer was unnamed before, which makes it impossible to access in shader nodes. Now the user can input a custom name in the modifier panel, then use that same name in a shader input node to access foam values.

RNA: fix compile issue with zero size arrays with old gcc.

Tweaks in convert tracking constraint to f-curves operator.

Fix #29322: 'Active Clip' not saving after appending.

Address for active clip used to be updated in direct scene linking,
should be in library linking.

Dynamic Paint:
* Vertex color output now works even if there is a constructive modifier, like ocean sim, before dpaint.
* Fixed a crash when canvas mesh had no vertices.
* Fix: Smudge was also processed for incompatible surface types causing corrupted output.

- pyapi mathutils.geometry.intersect_plane_plane
- isect_plane_plane_v3 uses better method
- minor refactor - arg name changes & some args as const.

Replace "&" with "and" since on windows it separates the string and causes errors in the console.

UI/RNA:
* Code cleanup.
