Attempted fix for #27482: game engine running slow due to revision 36698 which
fixed frame colors for letterbox drawing (happens when in camera view).

Cause is unclear, seems some sort of strange graphics driver thing on 32 bit.
Changes are a fix for the incorrect usage of glViewport, and avoiding the extra
clear if it's not needed.

Cycles: fix GLEW library build issue.

Windows installer and Path changes, fixing various issues:

* Windows installer not working for non-admin users and multiple users
* Addon scripts not installing next to user configuration
* Portable install not being taken into account in all places

The main problem was the windows installer was installing system scripts in
AppData next to the user configuration directory, which is not shared between
users. Now these are installed in ProgramFiles, and only addon scripts added
by the users go to AppData.

On all platforms, addon scripts were sometimes getting installed between
system scripts, because the scripts folder in the executable directory was
given precedence over the user configuration folder, that is no longer done
now. So addons now behave like user configuration, they are preserved even
if you download a newer build of the same blender version.

If you have an installation of 2.57 on windows, the addon install location
will not change until we do the version bump to 2.58, to avoid conflicts with
the existing the installed 2.57 version.

The old behavior of giving precedence to the local folder was done to support
portable install, where all configuration is written to the local folder. This
is now implemented differently: if and only if a "config" folder exists in the
local folder, portable install will be assumed, and files will only be written
to that local folder.

Cycles: some mix node blend modes not working correct:
subtract, screen, divide, difference, darken, lighten, overlay

patch by Sanne, thanks!

Moving BL_Action and BL_ActionManager to Ketsji to avoid linking issues with gcc

== FFMPEG ==

Fixed and added additional ffmpeg cruft checking. Oh dear.

== FFMPEG ==

... and another funny version patch, since OpenSuse obviously used some version "in-between"

own recent commits caused crash with the grease pencil in camera view, always pass rv3d argument now.
also found a bug where hex_to_rgb could use un-initialized memory.

== FFMPEG ==

Added some API compatibility code again, since some API-changes weren't even documented
(they even didn't do a proper version-bump, arghh!)

If it breaks again, please tell!

missed this in recent commit.

weight paint mirror, move duplicate code into a function.

== FFMPEG ==

* removed a lot of old cruft code for ancient ffmpeg versions
* made it compile again against latest ffmpeg / libav GIT
(also shouldn't break distro ffmpegs, since those API changes
have been introduced over a year ago. If it nevertheless breaks,
please send me an email)

remove BLI_streq() since it was hardly used, also replace string search with BLI_findstring().

split BLO_library_append_named_part into 2 function, one that adds objects into the scene and another that just links/appends.

sphinx docstrng formatting (some lines were getting really long)

use a dynamic enum for addons, annoyingly the enum was being generated from python for each of the addon buttons (~14 times per draw) which was noticeably slow, so disabling 'expand' for now.

Eventually it would be good to have the expanded buttons all using the same result from itemf().

AnimationExporter class refactoring.

Exported AnimationExporter class to a separate set of files.

support for dynamic items in bpy.props.EnumProperty(), the items keyword argument can optionally be a function rather then a list.

add the property as an argument to enum item functions, not used yet but needed for dynamic python enums.
