Tracking: Some minor improvements to copy-paste

- Deselect all existing tracks when pasteing, makes it
easier to tweak stuff after the paste.

- Make first of the pasted tracks active.

OpenNL: modify SuperLU to use doubles rather than floats, for better precision.

This helps to improve the accuracy of UV unwrapping and laplacian deform for
high poly meshes, which could get warped quite badly. It's not much slower,
doubles are pretty fast on modern CPUs, but it does double memory usage. This
seems acceptable as otherwise high poly meshes would not work correctly anyway.

Fixes T39004.

Fix for missing shortcuts for mask copy/paste

It's a safe fix and would be real cool to have in final release,
it makes roto even easier than mentioned in the previous commit.

Fix T41961: Crash by Copy n Paste splines to new mask without layer

It makes much more sense to ensure layer before pasteing, makes roto
as easy as it has never been before!

Fix T41885, muting broken for Blender Internal nodes in rendering.

Nodes don't have muting callbacks any more, so now have to check the
flag to prevent overwriting values on the stack that they share with
inputs.

OSX: ensure windows are restored at their saved position,
meaning here we need to take docksize into account

OpenGL fix: GL_COLOR_ARRAY is client state

Expose show brush property for UV sculpting.

Fix T41936: lender 2.72 Crashes on play on *Ubuntu 14.04

This commit is necessary to update to openal-soft 1.60.0 which
solves weird bug happening on ubuntu.

This is to be landed to the release branch.

Fix T41939: Dupliface: Inherit scale doesn't update viewport render.

Render needs un object update it seems...

Fix T41933: Node Editor: Crash occurs with Select by Suffix

Wrong usage of `BLI_str_partition_ex_utf8`...

This is to be backported to 2.72 branch.

Cycles: Better feedback about experimental features being used

Instead of having a label which basically duplicated the information
about experimental feature set being used (which had a bug because
it claimed experimental GPU kernel is used even if compute device is
CPU btw) now we've got an enum item icon.

So once you switched to experimental feature set you'll see an
exclamation mark icon in the enum, so you know something might be
unstable or slow.
