While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

This was an old bug which could be caused by saving after separating.
Changes from 79b703bb63 made this fail reliably.
Update shape key indices when they may be used again later.
Custom profiles in bevel allows the profile curve to be controlled by
manually placed control points. Orientation is regularized along
groups of edges, and the 'pipe case' is updated. This commit includes
many updates to comments and changed variable names as well.
A 'cutoff' vertex mesh method is added to bevel in addition to the
existing grid fill option for replacing vertices.
The UI of the bevel modifier and tool are updated and unified.
Also, a 'CurveProfile' widget is added to BKE for defining the profile
in the interface, which may be useful in other situations.
Many thanks to Howard, my mentor for this GSoC project.

Large objects with many separate pieces became unstably slow
(run for hours and not finish).
The entire original mesh was being duplicated twice per loose part.
In own tests, millions of vertices and thousands of loose parts
now run in around 5-15 seconds.
merge/dissolve distance is actually a maximum, not a minimum

clnor editing code was simply not checking at all whether it has
something to work on... Guess nobody had idea to edit custom normals on
a mesh that has no normals before! :P
This should probably be handled in a poll function too, to completely
disable those tools when there are no faces/loops, but let's keep it to
minimal changes at that point.
Merge code will generate temp normal editing data for affected loops,
but since it will later (by setting some edges/faces to smooth) alter
and extend affected clnor spaces, it will also need temp normal editing
data for some other loops around those vertices...
Using those clnor editing data in that code is a bit of an abuse, but on
the other hand that struct stores exactly what we need.
So simply added an option to generate that editing data for all clnors
of affected vertices.
See T64324 for discussion re improving normal editing ui.
As next step, remove the face_strength tool settings because
menu operator now includes that. Move face_strenth enum to
better place.
Remove normals toolbar panel because only thing left
(normal_vector) can stay hidden for copy/paste.
Remove add vector and multiply vector menu entries as
they are useless without ui method for specifying operand,
and they are very low utility operations anyway.
