Minor fix for notifiers & cleanup

Merge branch 'blender2.8' into workspaces

Merge branch 'blender2.8' into workspaces

Cleanup: use calloc for DNA data

ensures pad-members are set, avoids junk data in the file & quiets
memory checking tools.

Cleanup: use BLI_find util functions

Add/use utility macros for getters/setters in BKE_workspace.h

General cleanup of workspace files (naming, function ordering, etc)

Merge branch 'blender2.8' into workspaces

Sync with blender2.8, cleanup, remove unintentionally committed files

Remove DNA_workspace_types

Accidentally committed after choosing not to rename

Fix search menu using wrong search list in full window draw mode

Turns out we can't use static struct data here, so just adding logic for
freeing custom search data when needed.

Remove redundant TODO mark

workspaces.blend file contain nothing but workspaces (mostly), so there's
nothing to skip when reading.

Don't append temporary screen-layouts with workspaces

Bundle default workspace user configuration file with Blender

This contains nothing but the old screen-layouts converted into
workspaces (and "Default" layout/workspace is now called "General").

Note that this adds the workspaces.blend directly, no datatoc conversion
is used like for default startup.blend. Mainly for these two reasons:
* Appending only supports regular .blend files
* Regular .blend is much smaller than datatoc one (181kB vs. 1.4MB)

Rename workflow.blend -> workspaces.blend

Idea was that workflow.blend could be used for non-workspace data later,
but it's not worth the confusion it may cause.

Fix crash opening startup.blend as regular .blend

Also fixed incorrect context change.

Allow storing workspaces as part of user config (UI preliminary)

Adds a button in the User Preference Interface tab to save all
workspaces of the current file into [user config
path]/config/worflow.blend.
When clicking the button to add a new workspace, the menu will list
these then (and of course the option to duplicate current workspace).

Note that the operator currently overrides all workspaces in the config
file. There should be ways to add and remove workspaces from it instead,
but we need to figure out a good UI design for how to do that still.

Fix workspace mode syncing

Toggling off a mode didn't correctly update the workspace.
