Modifiers: every modifier now copies mesh settings, fixing texture space issues

Modifier stack evaluation would copy mesh settings other than mesh topology
automatically, outside of the individual modifier evaluation. This leads to hard
to understand code, and makes it unclear which settings are available in following
modifiers, and which only after the entire stack is evaluated.

Now every modifier is responsible to ensure the mesh it outputs preserves materials,
texture space and other settings, or alters them as needed.

Fix T68852: Link select crashes after knife project

Knife project switches out of vertex selection mode, but wouldnt do this
for all participating meshes.
Logic in edbm_select_linked_pick would switch the viewcontext multiple
times and the meshes selectmode was not in sync then, leading e.g.
finding a vertex in 'unified_findnearest' (because last of the meshes
selectmode was SCE_SELECT_VERTEX), but then later in
'EDBM_elem_from_selectmode' other meshes selectmode was not matching
SCE_SELECT_VERTEX, leading to crash...

Cleanup: Remove redundant name checking

The BKE function already does this checking.

Merge branch 'master' into greasepencil-object

Fix T70009: GPencil copied layer is linked to its original layer

As the layer and frame memory was duplicated, the pointers were connected to old data. This was solved when saved the file, but this was a bug. Also this required a duplication and clean all listbase items.

Now, instead to duplicate and clear memory for layers and frames, just create a new layer and frame. This solution fix the problem, it's faster and also keeps the code cleaner.

OpenVDB: speedup.

fix crash with negative emitter rate

Cycles: Small fix for deferred ray marching.

Fix T70033: Crash editing keymap operator

Expanding operator names could buffer overrun.

Cleanup: use uint,ushort,uchar for modifiers

Cleanup: spelling

Cleanup: Manpage: use 'https' blender.org URL instead of 'http' one.

Blender manpage generator: use blender build date instead of current time.

It makes much more sense to use the build timestamp of the Blender
binary used to generate that manpage, than the current time.

As a bonus, when Blender building makes use of the SOURCE_DATE_EPOCH envvar
(through CMake, since previous commit), this also propagate automatically
to that man page.

Inspired by D5756 by Bernhard M. Wiedemann (@bmwiedemann), thanks.

Use cmake TIMESTAMP for BUILD_DATE+TIME

Use cmake TIMESTAMP for BUILD_DATE+TIME
this simplifies code a lot
and even makes it more portable to other platforms

TIMESTAMP is available since cmake-2.8.11 ; blender already requires
cmake>=3.5 so that is fine.

Note that with CMake>=3.8, if defined, the SOURCE_DATE_EPOCH envvar
will be used by CMake here.
