4ff0126e89 C99 is now the C standard for all our C code. 
The main new feature is mixed variable declarations and code, which can help
reduce uninitialized variables or accidental variable reuse.

Due to incomplete C99 support in VS 2013, variable length arrays are not
supported, BLI_array_alloca must still be used. The header <tgmath.h> is also
not supported.

176b806626 BVH-overlap: add callback to BLI_bvhtree_overlap 
The callback checks if 2 nodes intersect (not just their AABB).

Advantages:
- theres no need to allocate overlaps which are later ignored.
- expensive intersection tests will run multi-threaded.

Currently only used for Python API.

cff288cf3a Use PyC_ParseBool to parse bools 
This could cause problems since they could be any int,
then passed directly to internal functions that assume bools.

18af73e461 Add mathutils.bvhtree API 
Originally D966 by @lukastoenne, with own additions

- trees can be initialized from Object's, BMesh,
  or passed in as vert+polygon arrays.
- original indices of ngons/faces are used. (instead of tessellated indices).
- ray_cast, find_nearest methods
- find overlapping faces between 2 trees

4050b49f97 increase mathutils callback count (BGE devs, read the log) 
This was causing the BGE to crash on Debug mode when built with "break on asserts", meaning the BGE was not debuggeable.
Please make sure to test patches in debug mode with the proper flags enabled before committing

7837f0e833 BLI_math 'compare' cleanup & enhancements. 
This commit:
* Adds a 'compare_ff' function for absolute 'almost equal' comparison of floats.
* Makes 'compare_vxvx' functions use that new 'compare_ff' one.
* Adds a 'compare_ff_relative' function for secured ulp-based relative comparison of floats.
* Adds matching 'compare_vxvx_relative' functions.
* Adds some basic tests for compare_ff_relative.

See https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/

Note that we could replace our python/mathutils' EXPP_FloatsAreEqual() by BLI's compare_ff_relative
(using a very small absolute max_diff), but these do not have exact same behavior...
Left a comment there for now, we can do it later if/when we are sure it won't break anything!
