GPencil: Initial support for GP Layers in Outliner

This is still very rudimentary, and lacks many things.
* This needs a better icon. Perhaps we can look into using colour swatches here
too like in all the other places?
* The "active" check needs to be implemented still
* Various restriction toggles to come still

GPencil: Initial support for Grease Pencil in the Outliner

This commit just adds entries for the Grease Pencil datablocks in the Outliner.
Currently, there's not much more to see here, but the following commits will see
to that.

Fix T43515: Initial velocity for fire bug

Visual representation of fire was generated before simulation step took place. This caused fire to essentially lag one simulation step behind, even though all emission areas were up to date.

Fix T42950: Smoke particle flow doesn't work with high res and subframes unless "set size" option is ticked.

Fix T43579: FBX Export shading issue (Broken normals?)

Error in custom split normals work, non-autosmooth normals != vertex normals!
Loops from flat faces shall take normal of their face, not their vertex.

Tsst...

cleanup: style

UserPrefs: increase max undo steps to 256

rename SIPO_AUTOVIEW -> SIPO_AUTO_VIEW_SELECTED

The term auto-view on its own isn't very meaningful

One more crashing instance for hashes

Slip tool accepts numerical input.

Get rid of no scaling for proxies for master, it causes FX to crash,
will code another workaround for gooseberry.

Graph Editor: Auto View

Auto View automatically adjusts the view based on selection, so that the view is
always focused on the current selection.
A checkbox in the header is used to access it and it works for the following
selection methods: Toggle All, Border, Circle, Lasso, Left, Right, More, Less,
Linked, Column (so all except of single selection, in which this can be a bit
annoying)

Fix T43578: Beauty Triangulation would hang in infinite loop, due to float rpecision issue.

Only recompute if cost is below -FLT_EPSILON, we can get cases where both cases generate
very tiny negative costs (see 'Cylinder.004' mesh in .blend attached to report).

Fix sequencer crashing after recent GHash refactor.

Code frees hash element while iterating - I don't think that's a good
idea but this should keep things working for now at least.

Add a precision to 'show group color' tooltip, that fcurve/action editors option was confusing users a bit.

Fix for scons + mingw64 warning flags fix

So, it turns out my changes here the other day were a bit too over-eager:
-Wdeclaration-after-statement and -Wstrict-prototypes only applied to C code
and not C++ (which that set of flags was getting included for too).

However, -Wno-char-subscripts is fine where it is now, so I've left it in place

Cycles: Some more constants fixes for fast math

Cycles: Use proper constant name for 1/pi in fast math

Some tweaks to support upcoming OSL-1.6

Doesn't mean we're 100% ready for the transition, but need to start somewhere
anyway. Changes:

- OSL is no longer supporting cpp and requires usage of Boost Wave.
So now Wave component of Boost is optionally demanded when looking for the
Boost libraries if OSL is enabled.

Only did this for Linux, MSVC seems already using Wave. Not sure about OSX.

- Because of the same reason OSL should be moved prior Boost for linker.

- Whole archive trick makes it so linking fails with duplicated symbols, so
removed it for the new OSL. Didn't see issues with this so far.

- Added some code to check OSL version on Linux. Would need to move all that
to FindOpenShadingLanguage.cmake which we can get from Cycles standalone
repository.

So in theory no affect on current stup would be made at all.

- Added some tweaks to buildbot files. It now seems to be happy with the new
OSL libraries, but again, those tweaks are not in action yet.

All this was tested on Linux only. Win/OSX might still need some tweaks to
support new OSL.

P.S. This doesn't mean we're pushing OSL update yet, just making some
preliminary tweaks to avoid entropy of PITA when we'll actually want to
switch.

Fix some UI messages from own recent merge, and RNA code checking for final '.', was a bit too rough.
