Jpeg: Fix write past array boundary

Was happening when image buffer had cryptomatte pass, which can easily
exceed 530 bytes used by the buffer.

Now default buffer is bumped to 1K, and also allowed to be heap-allocated
when really need bigger buffer.

Possible optimization is to allocate buffer once, but in practice those
re-allocations will not happen often, so keeping code simpler is not an
issue. Just something for a rainy day.

Fix broken Cycles test build after recent commit.

Broken by rB4ce9785e0158, please do full complete build before
committing!

API doc: info_gotcha: extend description of issues related to memory changes.

* Added a TL;DR first paragraph summarizing that one shall not keep any
reference to Blender data when modifying its container.

* Added some info about fact that adding items to some data containers
(like Collection) can also invalidate existing items (due to array
re-allocation).

* Added a Do/Don't example which shows a crash after adding some items
to a collection.

Related to T61297.

Cleanup: API doc 'info_gotcha': typos.

Add Abkhaz language to Blender (disabled for until we get some translated content).

Fix T61666: missing NULL_UNIT that stops iteration over units

Edit Mesh: Cleanup

Sculpt Draw: Add support for wireframe geometry

This introduce the wireframe batches. Creating the indices buffer does
not seems to slow down the sculpt in my testing (but it is kind of hard to
test reliably)

This includes a bit of cleanup in gpu_buffers.c.

Wireframe: Add workaround for osx wide wires

Cleanup: Remove old wireframe batch cache code

Wireframe: Fix Artifacts with MSAA

We blit the depth buffer into the MSAA depth buffer so that wires are
properly occluded. This also makes the "In front" option work with MSAA.

GPU: Change multisample resolve shader to output min depth

This will effectively make the AA passes thicker in some cases but it is
required for better AA on wireframes. The trick is to occlude the wire
passes so that they do not output fragment that could be behind actual
geometry.

Wireframe: Add depth offset to prevent zfighting of wireframe overlay

Wireframe: Refactor to use GL_LINES instead of triangles with alpha blend

This gets rid of the progressive fading of the edges as it does not work
with depth perception (sorting problem with alpha blending).

Clamp value in sheen calculation to fix fireflies.

Markers: Make marker lines in sequencer and graph editor optional

- Makes it possible to show a vertical line for every marker in the graph editor.
- Makes the marker line visiblity optional in the sequencer and graph editor.
