BLI_listbase: add `BLI_swaplinks` which swaps given links' positions in given list.

Can be much simpler and quicker than using remlink/insert functions.

UI Icons: add 'triangle-bar' left/right/up/down icons.

Fix sequencer clipboard with meta's containing ID references

Fix sequencer duplicate with only handle selected

Fix T42326 trim operator not cancelled by the escape key.

Don't change global compiler flags when FFmpeg is enabled

It should no be longer needed. If it causes the issues please let me know
to find a more cleaner solution.

Fix T42311, too many paint slots added.

Don't allow the add paint slot operator to redo. Also guard better against
excessive slot addition

Trim tool:

Effects strips in metastrips could be erratic.

Better fix for previous trim fix.

Fix T42313: Ruler always measures 0.0

Passing 'ar' to snapObjectsRayEx would apply a ray-offset.

Fix trim tools metastrip borders not getting updated correctly.

Merge trim tool from terrible_consequencer

The trim tool (T key) allows users to change the position of the
contents of a strip without moving the strip itself.

Optimization for mesh deform: use BLI_INLINE specifiers

This helps compiler to do detect stuff which might be inlined,
gives around 30% speedup on my laptop with test files from ZanQdo.

Fix T42189

Own mistake - not copying enough data.

Fix T42264: Negative scale & clipped-select fails

Thanks to mont29 for finding the cause.

Fix T42304: blender 2.72a 3D view object selected color wrong in 2.4x theme.

I would not have endured such a critical and monstruous bug one more femtosecond!

And even worse - active color was awfully wrong too! Shocking!

Fix T42303 Icons lost after loading window

The issue here is that if no matching winid is found, we destroy all
windows and their context with them. This will also delete the OpenGL
textures associated with the initial context, thus we lose the icons.
This patch makes sure a window is always kept for later so the initial
context does not get lost.

Thanks to Campbell and Ton for the discussion on the issue.

Fix typo in calculateCenterMedian that could give computed median point wrong values.

From soc-2014-shapekey branch, with minor edits by mont29 (Bastien Montagne).
