Cleanup: use enum typedef for manipulator drawstep

Correct last commit, for-loop included NULL check

Cleanup: remove next/prev from manipulator map

Fix manipulator Python API crash w/ undo

Split up manipulator free & unlink, so freeing window data doesn't
run callbacks that might use freed data.

Fix manipulator keymap initialization

Update flag was cleared before being checked
when registering after load.

Revert "Fix manipulator handles getting added each refresh"

This reverts commit 122706db9cd23c88775474750e99b57e74a3b9e5.

Would loose manipulators, will check for duplicates instead.

Manipulator: Check we don't add multiple times

BLI_memiter: minor cleanup

DwM: use BLI_memiter for draw storage & iteration

This will only be noticeable for drawing many instances.

In contrived use-case with many instances, and `USE_PROFILE` disabled
this can close to double playback FPS.

The option to disable this is left in the code in case we want to
debug memory use.

See D2756 for details.

DwM: add ability to disable the timer

This interferes with benchmarking draw times,
so this makes it easy to turn off.

BLI_memiter: Small API for many small allocations

- Each allocation can be a different size
(but should be smaller than the chunk size).
- Result can be looped over in order of allocation.
- Allocations are aligned to pointer size to avoid unaligned reads.

Property path generation fixes

Remove volatile, causing issues w/ GCC/ubsan

Should remove from master since its workaround for Cygwin
but too close to release.

Merge branch 'master' into blender2.8

Cleanup: quiet picky ubsan warnings

Cleanup: multistatement-macros warning

Cleanup: multistatement-macros warning

Merge branch 'master' into blender2.8

Replace magic numbers with deprecated names

The names aren't meaningful but means it wont
accidentally use valid names.

Also remove textured-font setting

Fix T52195: Sculpt from Python fails

When calling sculpt from Python,
setting 3D 'location' but not 2D 'mouse' stopped working in 2.78.

Now check if the operator is running non-interactively and
skip the mouse-over check.
