DNA/RNA changes

- replace ABC_ prefix w/ MOD_MESHSEQ_
- don't use abc_ prefix for DNA paths (this doesn't depend on alembic)
- use an enum-flag for read-data (multiple boolean options).

Curves: Batch extend operator

Started the implementation of the batch extend operator. Faulty memory handling on the Extend operator is currently causing it to fail.

Cleanup.

De-duplicate point reading logic, add support to read custom data for
points only meshes.

Expose reading flags to the UI.

Expose CacheFile.is_sequence to the UI, to avoid issues when checking
for sequences.

Remove old comment.

Make Blender Internal work with new local view design

Only got a rough overview over how BI works with layers and local view, but I think what I did here is enough/correct.

Increase max num of local views from 8 to 32

Prepare local view OP to work without layer bitfields

Merge branch 'master' into soc-2016-multiview

WIP: design RegionSpaceClip (split SpaceClip)

in the progress of seperating view-dependent data fields from SpaceClip
to RegionSpaceClip

Added option to run "average islands scale" before packing.

(user request from ba)

Move LocalView structs to DNA_screen_types.h

Use LocalLayerInfo struct for area visibility bits

Fix do_versions using wrong region list

Cycles: Fix a memory leak when cancelling a denoised render

Cycles: Fix another cause for NaN normals and a potential divide-by-zero in the background texture

Cycles: Add Debug build option that enables floating point exceptions

By enabling the new WITH_CYCLES_DEBUG_FPE, floating point exceptions are enabled in the CPU kernels.
That way, the debugger stops as soon as an invalid calculation is performed, which makes it a lot easier to track these issues.

Note that the option may cause problems in combination with the --debug-fpe runtime option.
