This patch changes the BVHCache implementation. It will use
a primitive array in stead of the ListBase. The locking is also
changed from a global lock to a per cache instance lock.
The performance of `gabby.blend` available on the cloud increased from 9.7
fps to 10.5 fps.

Source (i.e. other) mesh should not be modified in any case in modifier
evaluation case (this is forbidden by design and can lead to all kind of
threaded locks and crashes), and doing so even in operator case was
never a good idea either.
Now that we can specifically request needed data (poly and/or loop
normals) from evaluation code, we can finally get rid of those
computations inside data transfer/mesh remapping area.
This is hopefully the last remaining bit of this 'bad crashing code' in
datatransfer area.
In some cases (currently, only when using avanced mapping of loops),
code needs access to some cddata of the source mesh (CD_NORMAL...).
We need a way to inform calling code about that (actual issue requiring
this change is fixed in next commit).
BF-admins agree to remove header information that isn't useful,
to reduce noise.

Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
There is no point having operations that iterate over the whole
bit array as macros, so convert BLI_BITMAP_SET_ALL to a function.
Also, add more utilities for copying and manipulating masks.

Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
This was actually rather hairy, this code is huge and complicated, easy
to make mistakes...
Good thing is, it will allow for significant simplification and more
(name) cleanup in following commits ;)
`MREMAP_RAYCAST_APPROXIMATE_BVHEPSILON(ray_radius)` greatly increased the radius making for example that 0.1 becoming 1.5
Now the result is much more predictable.
This was... horribly wrong, CDDM will often *not* need to allocate
anything to return arrays of mesh items! Just check whether array
pointer is NULL.
Also, remove `DM_get_looptri_array`, that one is useless currently,
`dm->getLoopTriArray` will always return cached array (computing it if
needed).
Title says pretty much everything, we now have BKE and RNA funcs to get vertex, poly and
loop normals of a given shapekey.
This will be used e.g. in FBX exporter (shapekeys need normal data too).

Null-area face could generate an int overflow, and potential numerical imprecision in face area computation
could lead to negative number of rays-to-cast (though highly unlikely).
Also, use domnant axis of poly normal as 'flattening' one, instead of always using Z axis.
Points raised by Campbell, thanks!
