Fix T40031: cycles deformation motion blur wrong render on last frame of animation.

Another attempt to fully fix T40020: Freestyle: dashed lines crashes blender.

Problem report by flokkievids through rB047c3aa728a4bb944616a084805988714b796d52#1.
Thanks!

Freestyle: Revised a UI text for better understandability in the Outliner.

Fix T40029: Apply transform to empties reset their location

also add check for negative scale

Stop all dynamic enums using translations (from blend file data)

Fix: T40016 ID Names translated in menus

Fix T40020: Freestyle: dashed lines crashes blender.

The crash was due to an out-of-range vertex index reference that occured while
computing texture coordinates of strokes with tips.

Code cleanup

NLA Pushdown Operator: Active animdata option + More error handling

* If channel_index = -1, the pushdown operator will try to use the active AnimData
block. To see which one this will be, check the properties (NKEY) region in NLA Editor.
* Added more detailed error handling for the various cases where things are not
in a valid state for pushing down an action. This is notably to stop scripters
from putting the NLA into an inconsistent state.

NLA Editor: Added dedicated operator for the pushdown operation

Code Cleanup: Remove old deprecated NLA channel drawing code

NLA Editor: Polishing a few rough edges with the cleanup

NLA Editor: Second part of porting NLA Action channel to standard drawing system

This now works (barring one or two minor glitches and the operator on the pushdown
button being a bit of a hack). The old drawing code is still in place though, and
will be kept around for a little while yet while the last kinks are ironed out.

NLA Editor Drawing: Set up AnimChannelType callbacks for drawing NLA Editor

This commit lays some of the groundwork needed to port the last of the NLA Editor
channel types that's still defined using custom code. By moving this code over
to the newer standardised framework, this will enable widgets to have tooltips
to make it easier for users to find out what various buttons do.

Currently this isn't hooked up to anything though.

Fix T39928: Blender crash/freeze when game engine is started with animation played directly on camera object with parents.

Updating object IPOs is not currently thread-safe since it also updates
children. This leads to problems when parents and children are both
animated. For now, updating object IPOs is done in its own loop to avoid
threading issues.

Add check for LIKELY/UNLIKELY is CPU only

Cycles: avoid int->float conversions for pixel lookups

Gives ~3% speedup for image.blend test, and 6% for image heavy file.

Overall speedup in real-world use is likely much less.

Fix T40025: install_deps.sh generating wrong make flag for OSL

Most cases should be handled OK now (not all though, would make script way too much tricky -
bash is a hell of a messy language :/).

Cycles: use LIKELY/UNLIKELY macros

Gives overall ~3% speedup in own tests for BMW scene.

Style cleanup: indentation, braces
