Undoing masks in dyntopo leaked memory

Refactor to recent matcap built-ins to not use the built in system.
Those variables would get declared on fragment shader level and since we
use reserved opengl variables, some compilers would throw an error
(NVIDIA allows, some ATI compilers may break). Instead, use a separate
opengl built-in category especially for them. This works on NVIDIA, and
will wait for tests of this commit from ATI users.

Implement fame sliding from IE's cache line

UI: Tweak last commit for UIList and image scopes' grip size.

Sorry, forgot the --hold arg to last arc land, wanted to check this before pushing... :/

Replace resize code of image scopes by use of new GRIP button.

This deduplicates/simplifies some code. Also cleanup up a bit scopes UI code!

Use new GRIP button for uiList grab-resize.

This allows us to greatly simplifies the code, and get rid of a few hacks in uiList event handling!

Note autosize mode of uiList is now trigered by any value of list_grip below a given threshold, rather than the fixed zero value...

Add drag-resize to uiTemplatePreview (mat/tex/etc. preview widget).

This is done by adding a new button type, GRIP, similar to other numbuttons
(scroll, slider, ...), which here controls the preview height.

Then, we add a new DNA struct to be able to save that height in Blend files
(note I choose not to use Panel struct for this, because we would then have the
same limitation we used to have with uiLists, only one preview per panel
and no preview outside panel).

This implies a change to template_preview UI RNA/py API (each preview needs an ID),
but this is backward compatible, as by default datablock type will be used if no ID is
given (which means e.g. all material previews with no ID will have same height).

implement cache line for image editor

It works exactly the same as a cache line in movie clip editor.

Fix T39521: Render with two Blender processes on same computer: compression issues?

We need to salt temp exr filenames with pid, else several instances of Blender rendering
the same scene on same machine and using "Save Buffers" option would use the same files!

Rename "BLI_cpu.h" to "BLI_system.h" and add to it BLI_getpid() helper.

There is not much sense to have a whole BLI file just to check SSE2 on CPUs...
So idea is to rename it to more generic "BLI_system", and add to it more system-related
utils, like e.g. an include helper for getpid(), which allows to hide unix/windows
internals from rest of the code...

Fix T39547: Toggling render passes on active scene does not update
render layer nodes in a pinned tree from different scene.

The way these updates work is a nasty legacy hack:
https://developer.blender.org/diffusion/B/browse/master/source/blender/nodes/composite/node_composite_tree.c$277

This function is called //very frequently// by the get_from_context
method. However, this does not get called for pinned node trees, so
when showing a different scene's compositing nodes in the editor they
may not get updated correctly.

Now moved this update call out of get_from_context so it happens in any
case. Will be called no more frequently than before (on every redraw).
Eventually the depsgraph should handle this more precisely, it's just a
simple ID dependency anyway ...

Fix T39545: "Track selected markers", does not stop at end of video

Issue was cauzed by some weird clamping of current frame. Not sure
why it was here at the first point -- it's from the day0 of movie

Dyntopo: Delete OpenGL buffers of nodes that do not have any more
triangles.

It is possible to end up with such nodes using brushes in aggressive
collapse mode. Those nodes should normally be cleaned up, since they can
never be actually reused (adding more geometry to a node requires the
node having some geometry to begin with) but until we support dynamic
nodes, better delete those to avoid binding graphics driver resources.

If such zero elements buffers were used, GL error out of memory would be
reported.

D345 from Aleksandr Derbenev

Fix some redrawing and possibly other issues in dyntopo:

When node face gets deleted, added or exchanged, the nodes should update
their draw buffers, normals and bounding boxes. This was not being done
before so there were graphical glitches apparent, especially in collapse
mode.
