cleanup: OpenGL comment

Removed reference to GL 1.x since we no longer support that. ES is
likely in our future though!

OpenGL: remove some hacks/workarounds

Everything I've tested works fine without these hacks. Variety of Mac, Linux, Windows, Intel, nVidia, AMD.
If these workarounds are for old unsupported systems let's clean house.

OpenGL: remove glPointSize hack

Fix RNA_enum_set_identifier(), needs a context to handle correctly dynamic enums.

Correct check when no path can be found

Add add-ons catalog to links in preferences menu

D1715 by @Imaginer

Add select next/previous items to select menu

Editmesh select sub-menu 'Select All by Trait'

Similar to object mode 'Select All by Type',
This menu is for various options to select based on some rules.

Moving into a submenu removes clutter, and means we can add other selection types.

BMesh: add select next/prev operator

This uses selection history to select the next vert/edge/face based on surrounding topology.
Select previous just removes the last selected element.

Uses key-bindings: Ctrl-Shift +/-

Fix T46723: Issue with linking to rigs running Blender in new depsgraph mode

This isn't really ideal fix, but currently i can't tell how proxies should work
with the new dependency graph. This backward links are crazy, non-threadsafe
and mindblowing. Need to do some smarter/easier system.

addon_utils: improve docstrings

Also make error handler take the exception as its argument.

Fix error in recent commit

Select mirror multiple axis support

Previously you could only select mirror on X axis,
now support mirroring on multiple axis as well as more than one
(for mesh and lattice data).

Fix access possibly uninitialized armature's bounding box flag

Cleanup: use generic xyz axis enums

Cleanup: remove unused scene arg

Cycles: Update some API to be ready for OSL 1.6

While previous code was already compiling with OSL 1.6 it was using some symbols
which were considered deprecated in upstream.

This commit adds some ifdefs, but soon we'll get rid of all them rather soon
with the upcoming OIIO/OSL update.

Cycles: Update some types used form OSL

Some types were deprecated back in 2013, better to be prepared earlier for those
types being removed from upstream.

Cycles: Whitespace cleanup, extra space in the argument list

Seems we're really starting to need to have cpplint for Cycles.

Cycles: Cleanup, use "string_" prefix for functions in util_string

No functional changes, just makes it easier to track where the function
is coming from.
