leanup: style, use 'const' where possible, and simplified blend funcs.

Much better to use small loops when doing complex operations over color elements
(any serious compiler will flatten them anyway), avoids (some!) stupid mistakes when
editing their code.

Also, use min/max funcs instead of lengthier 'if (foo < 0) foo = 0'.

BMesh: callback for bmbvh so caller can choose faces

Bugfix T41240: Home key doesn't show everything on F-Curves

Own copy and paste typo in 73d157e meant that this was not in some cases,
the bounds calculated may be incorrect.

missed last commit

BLI_listbase: consistent name prefix

GHash: generic comparison for int[4]

OSX/buildbot: after recent scons fix, UTF lib linkage is handled dependent on config, so remove now obsolete lines

OSX/cmake: fix linking utf-functions if llvm is disabled

Fix T41223: F-Curve sliders won't update values during playback when mouse cursor is outside the left panel.

Fix T41228: Selection of bones bug.

Turns out to be mostly some cleanup in Pose select code, got rid of magic numbers
(now understand usual SEL_xxx enums) in ED_pose_deselectall(), which was renamed
to ED_pose_de_selectall, and have a new bool parameter to ignore visibility status
in its process (was the root of the reported issue).

Also factorized slightly "(de)select all" code. Yet this area could use much more
cleanup probably...

Fix T41227: Do not select unselectable items when unhiding them!

Fix T41174: Tangent space required UV map in Cycles

Now Cycles behaves in the same way as BI in terms of using
sphere projection of orco coordinates if there's no UV map
when calculating tangent space.

OSX/scons: Fix linking if llvm is not used ( new osl/llvm/oiio related )

Cycles: Make Glass Shader Color default to 1.0.

This came up a few times already, most of the time you want a clear white glass, and not a greyish like one. :)

Implement get_split_task_count to make device_network compile again.

BGE: Constraint wrapper fix.

1. This patch fix the KX_ConstraintWrapper documentation (radian instead of degrees).
2. It also adds the missing GENERIC_6DOF_CONSTRAINT constant.

Install_deps: Raise openexr/ilmbase magic numbers, looks to be needed...

Btw, if someone can explain me why OPENEXR_FORCE_REBUILD does not work like
all other force options... :/

OSX/buildbot: Fix 32bit compile by removing OSL/LLVM and add back UTF to Collada
- due OSL i386 never worked on OSX, the new libs do not even contain this arch !
- As we had to fix duplicated symbols from generic UTF finctions same in LLVM and COLLADA,
LLVM-less build must have UTF lib reenabled
