Try to use dynamic memory for shading groups

The reallocation of the memory produce weird things, so we keep allocation maximum number while we found better solution.

applied patch D2150.id8618.diff and fixed versioning_270.c

Fix error when drawing in an empty frame

If drawing new stroke in an empty frame, but the layer had previous frames, the cache must be set as dirty to avoid segment fault.

Merge branch '28' into custom-manipulators

Add Face-Map to select similar

Handy for setting up face-maps,
also allows selecting all faces with no assigned map.

Cached lnorspace array and added dirty Mechanic

Fix bad index use drawing deformed face centers

Clear pose draw data in BGE pose copy

Missed when removing face-map DNA

Merge branch '28' into custom-manipulators

Fix custom-bone display-at option

Resolve assert in weight paint mode w/ no weights

cleaned up some weird spaces

Fix Screen not being made local when appending workspace.

Need to make Screen linkable for this to work as expected, would not
expect any side-effect here - hopefully!

Minor cleanup.

Fix bad handling of 'extra' user for groups at their creation.

Was just keeping the default '1' user from `BKE_libblock_alloc()`,
instead of using correct way to handle extra virtual user needed when we
want to keep unused datablocks around...

Fix T51680: 'Delete Group' from Group view of Outliner does not work.

Do not call invoke ops from outliner's operations menus. Invoke op would
search again for item under mouse coordinates... when it is invoked!
Means often entry menu you would have clicked would not be over target
item, leading to either nothing or operation being applied to wrong item.

Note: about groups, there is another minor annoyance leading to some
assert - groups have an annoying virtual fake user which breaks
usercount, will see whether this is easily fixable. :|
