Remove unnecessary loop over polygon-loops

vert_to_poly & vert_to_loop are aligned so we can step over them at the
same time to avoid nested loops here.

Add assert to check this doesn't get out of sync

Direction may be zero length even when not first-evaluated

Fix accidental nested loop in vertex paint smudge

Also use return for BKE_pbvh_get_ccgdm

Severin suggested I move new brushes to versioning_270.c

surrounded symmetry axis checks with parenthesis just in case

Merge branch 'master' into soc-2016-pbvh-painting

Merge branch 'soc-2016-pbvh-painting' of git.blender.org:blender into soc-2016-pbvh-painting

Added support for multires for both vertex and weight paint. Fixed a masking bug.

Use 'unsigned int[3]' array for total color

Cleanup: Avoid redundant/accidental struct copying

Cleanup: move BKE_pbvh_vertex_iter_end into same scope as BKE_pbvh_vertex_iter_begin

It turns out this worked, but still reads awkwardly.

Cleanup: variable names, const correctness, formatting

This makes the code match more closely with BKE_mesh conventions.

Also remove unused WPaintDefer struct.

Cleanup: move WPaintData, VPaintData, WeightPaintInfo back into paint_vertex.c

There is no reason to make these public
Revert allocated ViewContext, its no longer needed.

Cleanup: headers

Cleanup: remove redundant headers-in-headers

This brings the branch closer to master.

Also remove unused 'indexar' & 'accumulate_stack'.

Cleanup: move inline ViewContext out of vpaint structs

This required a bunch of indirect includes,
change this for neater includes and a single allocation here isn't causing performance problems.

Cleanup: add OB_MODE_ALL_SCULPT

Makes it clear that we want to check for any modes using Object.sculpt

Cleanup: minor syntax/unused var

Cleanup: remove redundant nested header

De-duplicate vpaint symmetry draw functions

Also add missing classes to list
