DerivedMeshes clean up their draw-batch caches

No more "Not freed memory blocks"!

This code was almost ready 1 month ago, waiting for other pieces to fall into place.

Gawain: batch mode uses buffer ID funcs

The _discard functions now free their resources! These were waiting on thread-safe ID management, which we now have.

Gawain: immediate mode uses buffer ID funcs

These functions are called very infrequently.

Gawain: manage GL buffer IDs in a thread-safe way

Needed because deps graph can destroy objects from any thread. We ran into the same problem & solved it in GPU_buffers.

Implemented in C++11 since it provides the needed machinery. The interface is in C like the rest of Gawain.

[msvc] remove /opt all together and revert to the default behavior /opt:ref for release builds, /opt:noref for debug builds.

Comment: explain viewport & render pixel-size

It wasn't all that clear why both pixel-sizes are needed.

[msvc] change linker options from /opt:noref to /opt:ref, saves about 20% off the executable size

Nobody appears to know why this option was on (and just on for just x64 at that)

UI: Add 'x' icon to text buttons to clear content

This is useful e.g. for search buttons to quickly clear the filter string. We might want to make this optional for python scripts.

Fix T50065: Audaspace: some values of the lower limit of Factory.limit causes the factory not to play

Backport of upstream audaspace bugfix (ddd9a4d).

Remove sensor-size to int conversion

Currently harmless since the value is always set at its default (32).
Even so, it's confusing since its used with floats after.

Enable multi-selection editing by default (Alt-key behavior)

This means editing a property will now always affect all selected objects, bones or sequencer strips. Support for this was added in rBdfbb876d4660 but you had to hold the Alt-key to use it. The old behavior of only editing the active object will not be kept like decided in the 2.8 workflow meeting (reports comming). If you only want to edit the active object, you have to deselect others.

There are still a couple of issues to be resolved (listed below), but having it enabled by default helps testing and getting used to it and should motivate us to fix them ;)
To be fixed:
* Give users hint when edits are applied to all objects/bones/strips ("Applying to x objects") - there are ideas but we need to finalize and implement them
* Make it work better in corner cases (material editing, modifier property editing, etc)

Note: Values usually override the initial value of the object/bones/strips, except of number buttons where it depends if you enter the value (absolute override) or drag the value (add value change). This behavior is consistent with multi-button editing.

A number of other minor RNA fixes and precautionary safeguards against further crashes here

GPencil RNA API: "set_active" option for layer.new() and palette.new() is now true/enabled by default

To bring the API more into line with the UI (and the general expected behaviour of
Blender when it comes to adding stuff), newly created layers and palettes will be
made the active ones by default. It's possible to override this behaviour still
(e.g. in cases where you're auto-generating a large number of them), but otherwise,
this change will help prevent errors like T50123.

Fix T50123 - GreasePencil: Modifying name of new color in new palette via bpy segfaults

When there were no prior palettes, creating a new one didn't automatically make it active.
This caused problems when trying to rename the color, as the RNA code assumed that if there's
a color, it must come from the active palette.

This commit partially fixes the problem by ensuring that if there are no palettes, the first
one will always be made active.
