Cleanup: Move PanelType flag from DNA to BKE header

Since this flag isn't saved in files and PanelType itself is defined in
BKE, the flag makes more sense there.

Cleanup: Make panel type flag names more clear

The overlap with the `Panel` flags that start with "PNL" was quite
confusing because wasn't clear which enum a flag was from. The
new names are a bit longer, but the clarity is worth it.

GPencil: Merge GSoC curve edit mode

Differential Revision: https://developer.blender.org/D8660

This patch is the result of the GSoC 2020 "Editing Grease Pencil Strokes
Using Curves" project. It adds a submode to greasepencil edit mode that
allows for the transformation of greasepencil strokes using bezier
curves. More information about the project can be found
here: https://wiki.blender.org/wiki/User:Filedescriptor/GSoC_2020.

GPencil: Fix compiler warning, unused variable

UI: Remove remaining uses of old collection icon

After rB452a1c7b3838 there were still a few cases where the old
collection icon was used in the interface. Replace these with the new
filled collection icon.

Collections: Prevent setting scene collection color tag from rna

It should not be possible to set the scene collection's color tag
through rna. Also adds a missing notifier for setting the collection
color tag from python.

GPencil: Fix callback parameter list error

In the previous commit the bGPDframe parameter was removed, but this parameter is required to keep the same function signature.

GPencil: Fix unreported crash in some cases when duplicate a stroke

Some pointers were not initialized.

GPencil: Cleanup clang format

GPencil: Missing initialization in previous commit

Outliner: Fix memory errors in runtime data

Fix a heap-use-after-free when duplicating outliner editors, and fully
free runtime data when freeing outliner editors.

Cleanup: Simplify panel activate state function

This commit moves some of the logic around so that the logic in
panel_activate_state is clearly separated by the state being activated.
There are fewer nested and redundant checks, and it's easier to see
the progression of interaction with the panel handler.

Cleanup: Remove unecessary logic in panel code

Also use short for panel flag arguments to functions since it matches
the type in DNA, and remove a comment that isn't helpful.

BLI_math: add floor_power_of_10, ceil_power_of_10

Add utility functions to get the floor/ceiling of a float value
to the next power of 10.

UI: make add object tool experimental

Some changes here are planned which need feedback from users before
declaring this ready for the next release.

Add An Opacity Slider to Overlay Wireframe

This patch adds an opacity slider to the wireframe overlay. The previous
wireframe in dense geometry scenes could be too dark and sometimes the
user just wants an impression of the geometry during modelling.
