utils to API.
This patch is the root of the GHash rework, all other diff will be based on it:
Reduce average load from 3.0 to 0.75
----------------------------------
This is the big performance booster part, e.g. makes tracing a dyntopo stroke between 25% and 30% faster.
Not much to say about it, aside that it obviously increase memory footprint (about 25% - 30% too).
Add optional shrinking
----------------------------------
I.e. ghashes/gsets can now shrink their buckets array when you remove enough entries. This remains optional and OFF by default.
Add code to use masking instead of modulo
----------------------------------
Buckets indices are obtained from hashes by “reducing” the hash value into the valid bucket range. This can be done either by bit-masking, or using modulo operation.
The former is quicker, but requires real hashes, while the later is slower (average 10% impact on ghash operations) but can also be used as a 'fake' hashing on raw values, like e.g. indices.
In Blender currently not all ghash usages actually hash their keys, so we stick to modulo for now (masking is ifdef’ed out), we may however investigate the benefits of switching to masking with systematic very basic hashing later…
Add various missing API helpers
----------------------------------
I.e. a way to deep-copy a ghash/gset, and a way to (re-)reserve entries (i.e. manually grow or shrink the ghash after its creation).
Various code refactoring
----------------------------------
* Get rid of the 'hack' regarding ghash size when used as gset (it’s simpler and safer to have two structs defined here, and cast pointers as needed).
* Various re-shuffle and factorization in low-level internal code.
* Some work on hashing helpers, introducing some murmur2a-based hashing too.
Thanks a bunch to Campbell for the extensive review work. :)

This adds back rgb_to_grayscale,
not all color is managed or depends on the current loaded blend file's CM options.
Noted in comments that this is only to be used outside the CM pipeline.

This commit makes some preliminary fixes and tweaks aimed to make blender
compilable with C++11 feature set. This includes:
- Build system attribute to enable C++11 featureset.
It's for sure default OFF, but easy to enable to have a play around with
it and make sure all the stuff is compilable before we go C++11 for real.
- Changes in Compositor to use non-named cl_int structure fields.
This is because __STRICT_ANSI__ is defined by default by GCC and OpenCL
does not use named fields in this case.
- Changes to TYPE_CHECK() related on lack of typeof() in C++11
This uses decltype() instead with some trickery to make sure returned type
is not a reference.
- Changes for auto_ptr in Freestyle
This actually conditionally switches between auto_ptr and unique_ptr since
auto_ptr is deprecated in C++11. Seems to be not strictly needed but still
nice to be ready for such an update anyway/
This all based on changes form depsgraph_refactor branch apart from the weird
changes which were made in order to support MinGW compilation. Those parts of
change would need to be carefully reviewed again after official move to gcc49
in MinGW.
Tested on Linux with GCC-4.7 and Clang-3.5, other platforms are not tested and
likely needs some more tweaks.

Also add a faster, non-normalized version of the function.

We need to register the exception handler slightly differently here, as
well as adding DbgHelp as a library, but according to docs it should be
supported in recent Windows editions (Win XP included even).
We can try it first and revert if there are issues.

Own mistake in refactoring of `BLI_strncpy_wchar_as_utf8()`, if given size was exactly
the one needed, we'd lost last char (off-by-one error).
Many thanks to plasmasolutions (Thomas Beck) who found the issue and did
all the investigation work here!

Added conversion to and from exponential map representation. This
representation is useful for interpolation of > 2 quaternions, or in
PD controllers.
Implementation in C functions quat_to_expmap,
quat_normalized_to_expmap, and expmap_to_quat with Python API, unit
tests and documentation.
Added Quaternion.to_exponential_map() and Quaternion(3-vector) to
Python API.

Also, avoid calling ugly strcmp with '.' or '..', making direct char checks is
