A big cleaning patch by Bastien Montagne (thanks a lot!)

* Split and moved Cycles’ render layers panels into the render_layer
context as well (would be nice to hide this context when not needed,
e.g. with the BGE, but this is not so easy to do nicely...).

* Fixed some inconsistencies with trunk (probably due to svn merge
glitches) using r52858 as reference.  Also recovered the missing
release/bin/blender-softwaregl file.

* A bunch of style code fixes in Blender's own code (not Freestyle
itself yet): line lengths, spaces around operators, block formatting,
headers, etc.  In rna_linestyle.c, color_blend_items was replaced by
ramp_blend_items (exported from rna_material.c).
