This is added in the spirit of the general cycles GLSL system
which is pretty much WIP still.
This will only work on cycles at the moment but generating for blender
internal is possible too of course though it will be done in a separate
commit.
This hasn't been tested with all and every node in cycles, but
environment and regular textures with texture coordinates work.
There is some difference between the way cycles treats some coordinates,
which is in world space and the way GLSL treats them, which is in view
space.
We might want to explore and improve this further in the future.

commits.
Basically, we don't set a draw buffer until draw time comes. Also add
explicit validation function to validate after all textures have been
attached (could be done automatically at bind time too probably, but
left out for now)
Fixes the problem that for big sequences too many file handles were open at the same time.
Changes the playback handles that the audio sequencing code manages to be closed and reopened when needed. The metric used is the current playback position in relation to the strip. If the strip is more than 10 seconds (configurable) away from the playback cursor, the handle is released and reopened when needed.
See D915.
This patch includes the work done in the terrible consequencer branch
that hasn't been merged to master minus a few controversial and WIP
stuff, like strip parenting, new sequence data structs and cuddly
widgets.
What is included:
* Strip extensions only when slipping. It can very easily be made an
option but with a few strips with overlapping durations it makes view
too crowded and difficult to make out.
* Threaded waveform loading + code that restores waveforms on undo (not
used though, since sound_load recreates everything. There's a patch for
review D876)
* Toggle to enable backdrop in the strip sequence editor
* Toggle to easily turn on/off waveform display
* Snapping during transform on sequence boundaries. Snapping to start or
end of selection depends on position of mouse when invoking the operator
* Snapping of timeline indicator in sequencer to strip boundaries. To
use just press and hold ctrl while dragging.

The issue was noticed with gcc-4.7 (used by the release build environment)
which didn't generate optimal enough code for BVH references swap. Seems it
looked up for the assign operator for each of the reference structure members
even though nothing special was required for assignment.
Forcing compiler to use simple memory copy gives speedup of like 2-3 times.
The issue doesn't happen with OSX's clang and new gcc-4.9, but since we're
gonna to stick to gcc-4.7 for official releases for quite some time still it's
nice to have performance issues resolved for all the compilers.
Didn't put the code into #ifdef so if in the future some issues appears with
alignment or assignment which need to happen as an operator we notice this
earlier.
Previosuly, world was shown on the background if "Render Only" was used.
Now user should be able to set it independently. This is a prelude to
(drumroll)...
* Alpha Property was removed (Fix T42690)
* Some tweaks to make the panel look better again.
* Use abreviated form "Multiple Importance" everywhere, for consistency.
gpencil_data_duplicate() was being used for gp drawing undo buffers, where using an
exact copy is exactly what we want/need. Instead, the code here now has an additional
arg for determining whether a direct copy is warranted or not.
Textures attached to particle systems are now get their animation data listed
under the particle systems they are attached to now. This is the most convenient
and direct way that these can get included
