Only use the active face when it's selected.

This resolves a performance regression in 2.8x where every edit-mode
update performed an edit-mesh to mesh conversion.
Now the conversion will be lazily initialized if/when it's required.
New BKE_mesh_wrapper_* functions abstract over mesh data access.
Currently only edit-mesh and regular meshes are supported.
In the future sub-surface meshes may be supported too.

The `BM_mesh_bm_to_me()` function copies shape keys from the BMesh to
the Mesh. However, it tries to copy the same number of shape keys as are
defined on the target mesh. Since the target mesh does not necessarily
have the same number of shape keys as the BMesh, this would crash if the
target Mesh has more.
Found while performing some tests for {D7785}.

Surrounding includes with an 'extern "C"' block is not necessary anymore.
Also that made it harder to add any C++ code to some headers, or include headers
that have "optional" C++ code like `MEM_guardedalloc.h`.
I tested compilation on linux and windows (and got help from @LazyDodo).
If this still breaks compilation due to some linker error, the header containing
the symbol in question is probably missing an 'extern "C"' block.

Was flipping around the 0-1 range, now (optionally) flip around each tile.
Also added this option for BMesh bmo_mirror.

Edit-mesh interactive redo reset the meshes shape-key index.
Also copy the selection mode when copying meshes.

Starting select linked failed when the selected vertex or edge
was it's self delimiting.
Support using these elements for linked select
as long as they're part of an isolated selection.

Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

In some cases moved the checks into asserts,
to ensure changes in the future don't cause
the checks to become necessary again.

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.

Also remove unused errors.

This prevented indices from being set to temporary values,
which is needed in some situations.

- Replace 'unsigned' used on it's own with 'uint'.
- Replace 'unsigned const char' with 'const uchar'.

Use double precision since volume calculation is susceptible
to float precision errors.
|

- Don't duplicate the original vertices.
- Free old geometry before allocating the new geometry.

Follow up on T71865 which only reported the issue for shape keys.
|
|
This was an old bug which could be caused by saving after separating.
Changes from 79b703bb635e made this fail reliably.
Update shape key indices when they may be used again later.

|
|
Exposed by T71865, while the bug remains this resolves the crash.

Also correct some outdated symbol references,
add missing 'name' commands.

Allows to access/transform/restore edit-mode
coordinates in a generic way.

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.

|
|
|
Move logic into EDBM_automerge since this is meant to run after
transform and isn't a generic editing operation.
