Fix #29518: uv cylinder/sphere unwrap from menu didn't work same as using U key menu.

Disable markers when doing frame-by-frame tracking and tracker library returns failure

Tracks which were moved to close to boundary weren'haven't been disabled when doing
frame-by-frame tracking.

Make Hybrid tracker default for movie clips

Fix #29432: Marquee Select Bug

Moved tweak threshold value to user preferences

This threshold might be needed to be tweaked when working with tables, i.e.
to prevent tap+slight movement be treated as tweak event.

Merging r42461 through r42481 from trunk into soc-2011-tomato

Camera tracking: some bug fixes

- Fixed bug with not putting disabled markers properly when doing backwards tracking
- Fixed margin size calculating from pattern size which used to be double-sized
and prevented to track things on the image edges.

fix for NULL pointer free and add in some checks, while looking into bug [#29521],
add asserts so we know if an invalid active index is ever set.

correct missing argument error if CYCLES_OPTIMIZED_KERNEL_FLAGS isnt set

fix for uninitialized memory use drawing 'nan' vertex groups, noticed while looking into [#29521]

remove BMEMSET define, use memset instead

alternative fix for [#29338], now dont duplicate the vertex layer when calculating normals, instead only calculate face normals.

fix for noise module in driver namespace (was infact mathutils).

avoid looping through the polygons to find the maxium loop size by using BLI_array_declare, tested on optimized build and its slighly faster though IMHO this is easier to follow.

optimization for BLI_array_growitems (better put - improve inefficient method), BLI_array_growone was being called in a loop, even if the size of the allocated array was big enough for all items.

In this case now just adjust the count value since theres no need to loop,
when the allocation is not big enough BLI_array_growone in a loop is still used though.

Use bicubic interpolation for the tracker preview. It looks fantastic, but is
slower, so we may have to make this an option instead of the only choice.

added mesh_calc_normals_ex() which is mesh_calc_normals() with an option to skip recalculating the vertex normals (only calculate poly/face normals instead).

also removed unneeded allocation of face normals.

otherwise no functional change.

Make distortion panel be a bit more obvious label

Fix related to #29513: materials using nodes will output passes from the active
material node. This is a confusing system, but two features were missing from
2.4x that made this at least a bit more clear:

* The top right icon in the node now shows brighter again for the active node.
* Setting a material datablock in a node makes that node active.
