code cleanup: lazy init enum for node search

dof node; change how threshold is applied, rather then clip out pixels at the threshold, fade instead.

note: need to apply this change to opencl still.

Merging r49681 through r49707 from trunk into soc-2011-tomato

Sequencer: corrections to sequence cache invalidation

Sequencer: initial implementation of multithreaded effects

Added a framework to run effects in several threads. Port most
of effects to this new framework.

Still some work to be done here (some effects are not so easy to port)

Code cleanup: use defines instead of magic constants

Sequencer: do not invalidate sequences which are not blending with bottom machines

Style cleanup: whitespace

Sequencer: initial support of refreshing only changed sequences

Before this the the whole sequencer cache would be invalidated
when hanging sequence settings.

This was completely annoying because changing color balance
settings would re-load image file for which color balance
is happening on every change,

In fact it's still an issue if color balance is changing for
image strip itself, but if this strip has got effect and
color balance is changing for it file wouldn't be reloaded.

improvement to the DOF node, after blurring the radius buffer (derived from the depth), overlay with the original so pixels in focus are not mixed with out of focus pixels.

Search option for adding nodes.

The 'Add' menu in the node editor now has an option 'Search' at the top, which opens a separate popup for searching node types by name.

The operator for this is implemented completely in Python (this could also be done for the regular menu-based Add options in the future). There are a few necessary extensions to the RNA as well:

* The View2D struct in regions is now exposed. Currently only contains converter functions for coordinates from the region to the view (i.e. scrolled and zoomed view space). Used for converting mouse location to node space.

* The SpaceNode exposes the existing 'cursor_location' for operators to store mouse position beyond invoke calls. Not used for anything else (transforms) so far.

* The edit_tree in SpaceNode is also exposed, this is needed for operators to work correctly inside node groups.

DOF node: clamp blurring the zdepth radius buffer by the blur max. This could doo easily blur very high depths and cause artifacts.

data_to_c in cmake, not used yet.

Code cleanup - whitespace

Disable saving property defaults for many of the properties for animation-editor
click activated operators to prevent any further errors

Bugfix [#32250] Dubious selection mode in Dopesheet and Action Editor makes it
impossible to delete ungrouped channels

* Active flag wouldn't get cleared off selected Groups and FCurves when clicking
on them again to deselect them

* Disabled property defaults saving for click-handling operator for channels.
While testing the fix for this bug, I noticed that the property-defaults stuff
was leading to selections always defaulting to "extend" once this had been used
once.

Movie cache: add function to iterate through cache and remove items
using custom check function for this.

Currently unused, but would be helpful for sequencer cache.

Fix logic error in mipmap filter and refactor scaling routine to lower self cost by ~30%

Code cleanup: make some more functions more meaningful name

Style cleanup
