Merge branch 'blender-v2.90-release'

Fix T78730: CLOG writes/reads outside allocated memory.

Fix several issues in CLOG code:
* In `clg_str_reserve`, allocated memory may be bigger than requested
one, do not assign the latter back to `cstr->len_alloc`.
* `clg_str_vappendf` was mis-interpreting returned value from
`vsnprintf`, and completely mixing total allocated memory and extra
needed amount of memory to allocate...

Simplified code of `clg_str_vappendf` to only have allocating code
handled in one place, makes things easier to follow too.

Think this should also be beckported to 2.83.

GPUBatch & GPUImmediate: Use GPUShader instead of using raw OGL handle

Fix usercount not decrementing in `gpencil_stroke_separate_exec`

This is part of T79273 where separating a stroke would result in
multiuser gpencil data for the original object.
Real underlying issue seems to be that gpencil multiuser objects (also
the ones created by Alt+D duplicating) have a problem evaluating
modifiers correctly [this will need further investigation].
Not sure if this is a limitation of D5470?

This patch only corrects the usercount on separating [which already fixes
the scenario reported because singleuser gpencil modifiers work
correctly].

Note: we could have also called `ED_object_add_duplicate` with the
`USER_DUP_GPENCIL` dupflag -- that would have taken care of the usercount
--, but then the whole following logic in `gpencil_stroke_separate_exec`
would need to change from **adding** layers/frames/strokes to
**removing** these.

Fix T79369: BMesh.calc_volume() gave incorrect result

UV: path select support with sync-select enabled

Also improve region fill with edge-select enabled which often failed
to include both vertices from each edge in the resulting region.

Fix UV select with sync select enabled wasn't setting active

Cleanup: spelling

Fix ghash return value on 'Correct Face Attributes' with 'Keep Connect'

The result was somewhat unpredictable.
This error was recently introduced.

Cleanup: GPU: Remove GPU_draw.h and move fluid gpu function to DRW

Cleanup: Split gpu_texture_image.c into BKE and IMB modules

This is in order to disolve GPU_draw.h into more meaningful code blocks.

All the Image related function are in `image_gpu.c`.
All the MovieClip related function are in `movieclip.c`.

The IMB module now has a connection with GPU. This is not strickly
necessary and the code could be move to `image_gpu.c` if needed.

The Image garbage collection is also ported to `image_gpu.c`.
