Note that in master this is mere cleanup, which shall not change much things
(aside from FAKE_USER now being taken into account here too), and mostly
makes things more consistent, but in id-remap branch this becomes mandatory
due to better handling of this ugly 'ensure_real' stuff re user count.
The motion actuator goes out of its way to prevent setting zero velocities,
which should actually be supported. This patch just works around it as a
first test. We should investigate whether the flags
`m_bitLocalFlag.ZeroLinearVelocity` and `m_bitLocalFlag.ZeroAngularVelocity`
are actually needed/desired at all.
One of the issues that's already visible with this simple change, is
that objects aren't actually frozen but still move a little bit; see
test with {F241908}.

Looks like UI code can produce widgets with same left/top positions (in very narrow space case).
Not nice, but we do not really care, UI becomes unusable way before we reach that point anyway.
There was a bug in OpenSubdiv library which is now fixed by updating library in
the build environments.
Still requires testing, but now being at the beginning of release cycle is
should be safe to simply enable option and let everyone to test :)
RNA could define strings as dynamically sized,
but the interface ignored this and clamped them to UI_MAX_DRAW_STR.
Fixes T46734, also fixes possible pasting non-utf8 text into utf8 buttons.
We have callbacks for that, they also do some checks and help ensure things are done
correctly. Only place where this is assumed not true is blenloader (since here we
may affect refcount of library IDs as well...).
USER_ONE was only ensuring id->us was non-zero, while USER_REAL ensures
it is non-zero **and** >1 in case fake_user flag is set (which at least
ensures us unsetting fake_user won't leave id->us in invalid zero state).
CMake 3.0 ignores the suffixed COMPILE_DEFINITIONS_<CONFIG> variants if policy
CMP0043 is NEW, preferring instead to consume the unsuffixed COMPILE_DEFINITONS
property and evaluate generator expressions in it.
Setting the policy to OLD causes CMake 3.0 to not ignore those properties.
Use the suffixed properties for compatibility only for CMake versions older
than 3.0 using an explicit version check. Use the non-suffixed property with
generator expressions otherwise.
These definitions should mostly not be needed at all - CMake already sets
NDEBUG in suffixed CMAKE_CXX_FLAGS_<CONFIG> variables. The _DEBUG macro is
non-standard, but is used in several places in blender (usually in an OR
combination with the DEBUG macro). Additionally, blender overwrites (instead
of appending to) the CMAKE_CXX_FLAGS_<CONFIG> variables on WIN32.
Rather than try to fundamentally change how debug-macros are handled in
blender, change the buildsystem to keep the same behavior without requiring the
CMP0043 policy set to OLD.
As we can see in (original) read code, ob pointer in groupobject is actually a 'USER_ONE' case.
This was not done in 'add object to group' code, probably because we can assume objects always
have at least one user in that case? Made it explicit now. Also fixed foreach_ID_link looper.
In general we have waaayyyyyy too much 'own handling' of ID->us count in code currently,
will clean up that...
