Fix T52515: Crash on BMesh.to_mesh()

Fix minor Mesh -> BMesh conversion issues

- Vertex only meshes never restored their selection history.
- Select history was cleared on the source instead of the target.

Simple Optimizations:
- Avoid O(n^2) linked list looping that checked the entire list before
adding elements (NULL values in the source array to prevent dupes).
- Re-use vert & edge lookup tables instead of allocating new ones.

Docs: rename var and comment how it's used

switch_from_camera wasn't right since it was used for auto-perspective.

Increase max/min frame range to over a million

For some specific pipelines (e.g., holographic rendering) you can easily
need over a million frames (1k * 1k view angles).

It seems a corner case, but there is no real reason not to allow users
doing that.

That said we do loose subframe precision in the highest frame range. Which can
affect motionblur. The current maximum sub-frame precision we have is 16.
While the previous limit of 500k frames has a precision of 32.

Thanks to Campbell Barton for the help here.

Fix T52472: VSE Audio Volume not set immediately

Audio mixing is done with volume interpolation. A new handle started at
volume 1, now starting at volume 0 for a smooth fade in.

Fix T52588: Shape key value driver variables of duplicated object sets refer to old objects.

Regression since 2.78, to be backported to 2.79.

Fix T52498: Deleting force field doesn't remove "Surface" from modifier stack.

Logic in `ED_object_check_force_modifiers` was inconsistent between add
and remove modifier cases.

Should be safe enough for 2.79.

Fix T52478: Error report "Shrinkwrap: out of memory" on invisible target.

Shrinkwrap must check it does have valid target data.

Safe for 2.79 release.

Fix T52538: Outliner crash when displaying groups and using Show Active on editmode bone not in any groups

There's no guaranty that given ID is found in current outliner tree...

Safe for 2.79, though not a regression.

Cycles: Mark pixels with negative values as outliers

If a pixel has negative components, something already went wrong, so the best option is to just ignore it.

Should be good for 2.79.

Fix T52481: After making all local, local proxies of linked data get broken after file save and reload.

Issue was nasty hidden one, the dual status (mix of local and linked)
of proxies striking again.

Here, remapping process was considering obdata pointer of proxies as
indirect usage, hence clearing the 'LIB_TAG_EXTERN' of obdata pointer.
That would make savetoblend code not store any 'lib placeholder' for
obdata data-block, which was hence lost on next file read.

Another (probably better) solution here would be to actually consider
obdata of proxies are fully indirect usage, and simply reassign proxies
from their linked object's obdata on file read...

However, that change shall be safer for now, probably good for 2.79 too.

Cycles: Fix stack overflow during traversal caused by floating overflow

Would be nice to be able to catch this with assert as well, will see what would
be the best way to do this/.

Need to verify with Mai that this solves crash for her and maybe consider
porting this to 2.79.

Fix T51805: Overlapping volumes renders incorrect on AMD GPU

We need to make sure we can store all volume closures for all objects in volume
stack. This is a bit tricky to detect what would be the "nestness" level of
volumes so for now use maximum possible stack depth. Might cause some slowdown,
but better to give reliable render output than to fail quickly.

Should be safe for 2.79 after extra eyes.

Fix T52218: Missing update when reconnecting node

If node was connected to output, we tag tree for update no matter where
the node was re-plugged to.

Should be safe for 2.79.

Fix T52466: Silence search for button_context menu type.

We were showing "search for unknown menutype WM_MT_button_context" messages in terminal which were not helpful for users, so now they are disabled.
