Camera tracking: minor code cleanup of RNA file, no functional changes

Camera tracking: tracks copy/paste operator

This commit implements basic clipboard support for movie tracking data
int clip editor. Used own implementation of clipboard like it's done
for sequencer.
Ideally it needed to be switched to more general clipboard system, but
currently this system is designed for text data only and it need to
be re-designed itself. But this feature is quite useful since object
tracking is implemented, so it should be OK to live with such own
implementation for a while.

Camera tracking: marker's frame number is now writable from python api

Camera tracking: improvements of python api

- marker_find_frame moved to MovieTrack.markers and called find_frame
- Added MovieTrack.markers.insert_frame to insert marker at specified frame
- Added MovieTrack.markers.delete_frame to delete marker from specified frame

ui typo + small fix

Blender internally deals with Font Objects, but as far as the user is concerned they are Text Objects.
Which, btw, makes me wonder why we have an 'F' as the logo for Text objects, and why the ob.type is 'FONT' in python

(I guess it's a Font Data for a Text object)

Cycles: multi GPU rendering support.

The rendering device is now set in User Preferences > System, where you can
choose between OpenCL/CUDA and devices. Per scene you can then still choose
to use CPU or GPU rendering.

Load balancing still needs to be improved, now it just splits the entire
render in two, that will be done in a separate commit.

Cycles: show elapsed time for F12/background render.

Cycles: small tweak to checker texture, scale rather than add with epsilon,
looks a bit better on all sides of a mesh.

Fix #29835: joining meshes leads to crash

Fix #29793: Physics go crazy if frames get skipped

Calculate cloth and softbody only for single frame time deltas
(like it's already done for smoke)

have add_weight_mcol_dm() set the 4th corner of a tri faces color to 0, otherwise uninitialized memory gets copied about.

WIP script to check results of different modifier combinations and display modes, useful for validating bmesh changes don't break specific modifier combinations.

Tag unused argument

bugfix for solidify modifier rim faces which were created from triangles, would get wrong customdata copied since it used the 4th index of a tri.

fixed already in bmesh.

Typo fix - thanks "Olson" on IRC!

dont draw object center dot for opengl render

fix an error rendering opengl weightpaint data wasn't working when python initialized opengl render on startup (needed for testing script).

Fix #29828: Reloading background movie clip crashes Blender

Crash was caused by invalidating scopes used by space clip editors. It shouldn't
actually happen in movie clip reload operator due to it will happen on NA_EDITED
notifier handler sent to movie clip context.

Cycles: checker texture node, patch by Thomas.

Color:

* Accelerated sRGB <=> linear conversion using lookup table, this can speed up
loading of images in the compositor and simple renders quite a bit.
* Dithering now uses the Floyd-Steinberg algorithm. Previously it would simply
randomize each pixel slightly, adding noise, now that should be reduced.

Patch #29309 by David M.
