These changes are to make the bmesh api more consistent and easier to learn, grouping similar functions which is convenient for autocomplete.
This uses similar convention to RNA.
* use face/loop/edge/vert as a prefix for functions.
* use 'elem' as a prefix too for functions that can take any type with a BMHeader.
* changed from camel case to underscore separated (like RNA).
This commit extends limit of ID and objects to 64 (it means 63 meaning
characters and 1 for zero-terminator). CustomData layers names are also
extended.
Changed DNA structures and all places where length constants were hardcoded.
All names which are "generating" from ID block should be limited by MAX_ID_NAME-2,
all non-id names now has got own define called MAX_NAME which should be used all
over for non-id names to make further name migration stuff easier.
All name fields in DNA now have comment with constant which corresponds to
hardcoded numeric value which should make it easier to further update this
limits or even switch to non-hardcoded values in DNA.
Special thanks to Campbell who helped figuring out some issues and helped a lot
in finding all cases where hardcoded valued were still used in code.
Both of forwards and backwards compatibility is stored with blender versions newer
than January 5, 2011. Older versions had issue with placing null-terminator to
DNA strings on file load which will lead to some unpredictable behavior or even
crashes.
inconsistent with similar functions & math notation:
mul_m4_m4m4(R, B, A) => mult_m4_m4m4(R, A, B)
mul_m3_m3m4(R, B, A) => mult_m3_m3m4(R, A, B)
For branch maintainers, it should be relatively simple to fix things manually,
it's also possible run this script after merging to do automatic replacement:

The only way to achieve this is to re-load editMesh.
After this commit you can't iterate through vertices and insert
hooks/parents from script anymore -- this operators are now
treated as topology-changing and shouldn't be used when iterating
via geometries.
Such load/make edit structures introduced regression into iterators
via object's geometry (vertices, edges, control points and so) when
adding hooks in the body of this iterator.
Fix for wrong index should be non-destructable for geometry.
This will fix#28506: Unusual behavior in curves.
Use quite easy and stupid approach like it used for shape keys:
re-make editmesh (editcurve or editlattice) before creating index array
for hook or storing vertex index in parenting object.
Even if hook was added in "current" edit mode, it should be re-mapped on
loading edit data because topology could be changed after it was created.
Such kind of re-loading edit structures is the easiest way for now to
update keyindexes to relevant state.
Also, fixed bug with not re-mapping indices for vertex-parented objects.
Really old error, not sure why it wasn't noticed yet.
