Cycles OSL: image texture lookup optimization, acquire the per thread handle
for texture system in advance. Patch by Martijn Berger, with some tweaks.

There was about a 10% performance improvement on OS X in my tests with the
images.blend test file. This may be less on other platforms because OS X has
particularly slow mutex locks.

Fix build warnings with clang and UNUSED_RESULT_ATTR (attribute declaration must precede definition).

Fix wrong cycles cmake + msvc build flags with relwithdebinfo and minsizerel.
Patch by Karsten Schwenk.

fix for divide by zero when border render size causes zero pixel width

fix for blender-internal viewport render looking fuzzy, don't filter the image

border render with cycles had 1 pixel offset on the top-right edge of the image, issue was caused by wmSubWindowScissorSet adding 1 to the ar->drawrct, now only add the padding when drawing the entire area

minor glitch with border drawing, use glRecti rather then glRectf, so rounding matches the border render

use api function for rect intersection

Code cleanup / Cycles:
* Various string and comment fixes.

mempool api cleanup: differentiate mempool functions that allocate a pointer lookup table from allocating the data as a contiguous array,
call these functions BLI_mempool_as_table(), BLI_mempool_as_array(), the N prefixed versions of these functions return newly allocated arrays.

code cleanup: remove redundant NULL checks

add c++/guardedalloc to more freestyle classes, also remove redundant 'public:'

code cleanup: replace strcpy with BLI_strncpy for fixed size strings, and correct some harmless but incorrect sizeof() use

fix for 2 memory leaks in dualcon library, quite bad since they leaked on every evaluation.

Support WITH_CXX_GUARDEDALLOC for dualcon library

more consistent use of checks of BLI_open(), check 'fd < 0' rather then -1. packedfile incorrectly treated 0 as an error value. best not be vague/sloppy with this.

fix memory leak in KX_ObstacleSimulation

fix for BL_ArmatureConstraint::UpdateTarget(), was getting the pose from the target, not the subtarget.

Cycles / OpenCL:
* Was broken after Blackbody merge, forgot to rename a struct...

add missing NULL check in RB_dworld_export if fopen fails.
