Update Object Mode Toolbar Tabs

This updates the object mode toolbar tabs to reflect the rationale from the Edit Mode tabs.
- Rename "Basic" to "Tools"
- Put "Transform" into it's own panel within Tools
- Also rename Edit Mode "Mesh Tools" to "Tools" for consistency and shorter names
- Ensure Tools tabs are in same location between Edit and Object modes
- Remove redundant "Transform" label from Transform panel

Code cleanup: suffix vars to make obvious they are squared

Fix: Compile error due to missing #define for MSVC9 (VisualC++ 2008)

Added some relevant #defines copied from externlibmvthird_partymsinttypes to BLI_sys_types.h so they can be used in blenlib. Made smallhash.c use the BLI_sys_types.h include rather than including <stdint.h> directly

Freestyle: Fix for iterations over 0D elements in the reversed order.

The revision is concerned with Interface0DIterator and StrokeVertexIterator.
These iterators can be generated by Interface1D::vertices_end() and
Stroke::stroke_vertices_end(), respectively. These methods return an
iterator poinitng the next index of the last 0D element (i.e., iterator's is_end
property is true). When the iterators created in this way are used with
Python's iterator protocol (e.g., in a for-loop), iterations over 0D elements
are automatically performed in the reversed order. This functionality was
broken after recent revisions concerning Freestyle iterators.

Also made minor code cleanup (white space).

Docstring updates and code cleanup by flokkievids (Folkert de Vries).

Code cleanup (mostly indentation and white space).

Fix for iterators' at_start flag left unset in C++ to Python conversion utility functions.
Also changed the type of the 'reversed' flag from int to bool.

Imported D222 Diff 2 (ID 781) by flokkievids (Folkert de Vries).

Add include needed for clang, quiet warning

BMesh: optimize loop_find_regions, reserve array size

BMesh: optimize lookups for triangle fill

Smallhash: add reserve option to avoid resizing when size is known

Smallhash: fixes/improvements

- use magic numbers based on uintptr max, not uint max, to avoid possible collisions with real pointer values on 64bit systems.
- comment BLI_smallhash_remove for now, its not used.
- added smallhash_val_is_used replacing ELEM() checks
- updated docs

Smallhash: optimizations

- remove static array used only for copying (use alloca on resize)
- set SMSTACKSIZE to one of the values in 'hashsizes' since the full available size was never used.
- ensure ~1.5x as many buckets as entries, was 3x which caused malloc's quite early on.

Code cleanup: use length squared where possible

Math lib: simplify size_to_mat4 and use in b_bone_spline_setup

Math lib: add axis_angle_normalized_to_quat, use when length is known

Fix T38432, Fix 38432: more stupid error in view3d ray code, sorry about that.

Cycles: less instructions for CPU perlin code

Also move shuffle() in bvh traversal back (was accidentally lost in SSE hair revert)

Fix player stub after type change
