GPencil: Change Opacity modifier

- Replace UI text.
- Change factor increment to 0.01 and precision 2.

EEVEE: Fix memleak when G.is_break is set from another thread

Cleanup: EEVEE: Use interpf instead of custom lerp

Fix crash when open default template

As soon you select the default template, Blender crash on Winodws.

This was introduced in commit {0b626703}

Merge branch 'master' of git://git.blender.org/blender

Cleanup: internal changes to cursor resetting

- Move gizmo cursor check into ED_region_cursor_set so the result of
calling this function is the same as flagging for cursor update.

- Use tagging in ui_popup_block_remove which avoids adding a
mouse-move event in case the cursor needs to be changed again.

Audaspace: Various fixes

- Fixed uninitialized result used in DynamicMusic::seek().

The comment to this function says false is returned if the handle
is invalid, while in practice non-initialized value will be returned.

- Spelling typos in comment.

- Silence -Wdelete-non-abstract-non-virtual-dtor warning.

use new 'unique realloc' of ID.

that way we do not have to stupidly ensure unique addresses of all IDs
read during an undo step, but only for those we actually need.

Combined with the 'almost always reuse old address' feature of undo swap
branch, this should ensure us to almost never call that code in
practice.

Fix T73593: Drivers on hide_viewport and hide_render are unreliable

This fixes a threading issue (T73593) between drivers that write to the
same memory address. Driver nodes in the depsgraph now get relations to
each other in order to ensure serialisation.

These relations are only added between drivers that target the same
struct in RNA, which is determined by removing everything after the last
period. For example, a driver with data path
`pose.bones["Arm_L"].rotation_euler[2]` will be grouped with all other
drivers on that datablock with a data path that starts with
`pose.bones["Arm_L"]` to form a 'driver group'.

To find a suitable relation within such a driver group, say the relation
(from ? to), a depth-first search is performed (turned out to be
marginally faster than a breadth-first in my test case) to see whether
this will create a cycle, and to see whether there already is such a
connection (direct or transitive). This is done by recursively
inspecting the incoming connections of the 'to' node and thereby walking
from it towards the 'from' node. This is an order of magnitde faster
than inspecting the outgoing connections of the 'from' node.

This approach generalises the special case for array properties, so the
code to support that special case has been removed from
`DepsgraphRelationBuilder::build_animdata_drivers()`.

A test on the Spring rig [1] shows that this process adds approximately
8% to the build time of the dependency graph. In my test case, it takes
28 ms for this process on a total 329 ms construction time. However,
since it also made some code obsolete, it only adds 24 ms (=8%) to the
construction time. I have experimented with a simple cache to keep track
of known-connected (from, to) node pairs, but this did not significantly
improve the timing.

Note that animation data and drivers are already connected by a
relation, which means that animating a field and also changing it with a
driver will not cause conflicts.
