Fix T50305: When adding new ID with same name as existing, Blender could generate invalid utf-8 ID name.

`check_for_dupid()` would roughly truncate existing name, without doing any utf-8 validation.

Fix (unreported) fully broken 'sanitize utf-8' helper.

That code was a joke, letting some invalid utf8 bytes pass, returning
wrong offset for some invalid sequences, not to mention length and
pointer easily going out of sync, NULL final byte being 'forgotten' by
memcpy, etc. etc.

The miracle here is that we could survive using this for so long!
Probably because we do not use utf-8 sanitizing enough in Blender,
actually... :/

Add BLI_string_utf8 specific test.

This test should ensure we correctly detect all invalid utf-8 sequences in a given string.

DISCLAIMER:
Do not run this with current code - you'll either laugh or cry, nearly *all* checks fail!

Fix missing `particlemode` context mode, after recent particle-removal revert.

This caused the particle mode tools panel to appear in object mode, where it
misses some contextual data and spews python exceptions.

Merge branch 'master' into blender2.8

Please **DO NOT** add changes from master when it's totally uneeded!

Changes to BLI_ area most certainly shall *always* be done in master,
there is absolutely no point in adding more diff between the two
branches than needed, will only makes merging more cumbersome!

Conflicts:
CMakeLists.txt
source/blender/blenlib/intern/math_vector_inline.c

Add new operator, ED_OT_undo_redo, to allow py tools to trigger that action.

Patch D2430 by @raa, thanks.

Fix T50334: Also select indirectly imported objects when linking/appending.

Since we create a base and instantiate them, they become directly
linked, so makes sense to also select them if requested.

Freestyle: fix typo in console message.

Patch D2270 by Anthony Edlin (@krash), thanks.

Edits to user prefs NDOF UI

Fix T49848: bevel of spiral gets bigger and bigger widths.

This is the same issue as was fixed with T39486: the adjustment pass
that tries to equalize different widths at either end of an edge
sometimes causes the widths to get bigger and bigger.
The previous fix was to let "clamp_overlap" do double duty as a way
to limit this behavior. But clearly this is undiscoverable, as the
current bug report shows. So I put in an "auto-limiting" mode that
detects when adjustments are going crazy and then acts as if
clamp_overlap were set.
The reason we can't always act as if clamp_overlap is set is that
certain models (e.g., Bent_test in regression tests) look bad if
that is enabled.

Revert particle system and point cache removal in blender2.8 branch.

This reverts commit 5aa19be91263a249ffae75573e3b32f24269d890 and b4a721af694817fa921b119df83d33ede7d7fed0.

Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.

UI: Make icon-only buttons for enum items with empty label.
