Adds thin/default/thick modes to add -1/0/1 to the auto detected line width,
while leaving the overall UI scale unchanged.
Also tweaks the default line width threshold, so thicker lines start from
slightly high UI scales.

Since we added auto DPI on Linux, on some systems the UI draws smaller than before
due to the monitor reporting DPI values like 88. Blender font drawing gives quite
blurry results for such slightly smaller DPI, apparently because the builtin font
isn't really designed for such small font sizes. As a workaround this clamps the
auto DPI to minimum 96, since the main case we are interested in supporting is
high DPI displays anyway.

This commit does the main integration of workspaces, which is a design we agreed on during the 2.8 UI workshop (see https://wiki.blender.org/index.php/Dev:2.8/UI/Workshop_Writeup)
Workspaces should generally be stable, I'm not aware of any remaining bugs (or I've forgotten them :) ). If you find any, let me know!
(Exception: mode switching button might get out of sync with actual mode in some cases, would consider that a limitation/ToDo. Needs to be resolved at some point.)
== Main Changes/Features
* Introduces the new Workspaces as data-blocks.
* Allow storing a number of custom workspaces as part of the user configuration. Needs further work to allow adding and deleting individual workspaces.
* Bundle a default workspace configuration with Blender (current screen-layouts converted to workspaces).
* Pressing button to add a workspace spawns a menu to select between "Duplicate Current" and the workspaces from the user configuration. If no workspaces are stored in the user configuration, the default workspaces are listed instead.
* Store screen-layouts (`bScreen`) per workspace.
* Store an active screen-layout per workspace. Changing the workspace will enable this layout.
* Store active mode in workspace. Changing the workspace will also enter the mode of the new workspace. (Note that we still store the active mode in the object, moving this completely to workspaces is a separate project.)
* Store an active render layer per workspace.
* Moved mode switch from 3D View header to Info Editor header.
* Store active scene in window (not directly workspace related, but overlaps quite a bit).
* Removed 'Use Global Scene' User Preference option.
* Compatibility with old files - a new workspace is created for every screen-layout of old files. Old Blender versions should be able to read files saved with workspace support as well.
* Default .blend only contains one workspace ("General").
* Support appending workspaces.
Opening files without UI and commandline rendering should work fine.
Note that the UI is temporary! We plan to introduce a new global topbar
that contains the workspace options and tabs for switching workspaces.
== Technical Notes
* Workspaces are data-blocks.
* Adding and removing `bScreen`s should be done through `ED_workspace_layout` API now.
* A workspace can be active in multiple windows at the same time.
* The mode menu (which is now in the Info Editor header) doesn't display "Grease Pencil Edit" mode anymore since its availability depends on the active editor. Will be fixed by making Grease Pencil an own object type (as planned).
* The button to change the active workspace object mode may get out of sync with the mode of the active object. Will either be resolved by moving mode out of object data, or we'll disable workspace modes again (there's a `#define USE_WORKSPACE_MODE` for that).
* Screen-layouts (`bScreen`) are IDs and thus stored in a main list-base. Had to add a wrapper `WorkSpaceLayout` so we can store them in a list-base within workspaces, too. On the long run we could completely replace `bScreen` by workspace structs.
* `WorkSpace` types use some special compiler trickery to allow marking structs and struct members as private. BKE_workspace API should be used for accessing those.
* Added scene operators `SCENE_OT_`. Was previously done through screen operators.
== BPY API Changes
* Removed `Screen.scene`, added `Window.scene`
* Removed `UserPreferencesView.use_global_scene`
* Added `Context.workspace`, `Window.workspace` and `BlendData.workspaces`
* Added `bpy.types.WorkSpace` containing `screens`, `object_mode` and `render_layer`
* Added Screen.layout_name for the layout name that'll be displayed in the UI (may differ from internal name)
== What's left?
* There are a few open design questions (T50521). We should find the needed answers and implement them.
* Allow adding and removing individual workspaces from workspace configuration (needs UI design).
* Get the override system ready and support overrides per workspace.
* Support custom UI setups as part of workspaces (hidden panels, hidden buttons, customizable toolbars, etc).
* Allow enabling add-ons per workspace.
* Support custom workspace keymaps.
* Remove special exception for workspaces in linking code (so they're always appended, never linked). Depends on a few things, so best to solve later.
* Get the topbar done.
* Workspaces need a proper icon, current one is just a placeholder :)

rB870440dee910c9 just did NULL-check for Main pointer, actual issue is
that bContext pointer was NULL. This can be fixed by ensuring
PROP_ENUM_NO_CONTEXT flag is not set by calling
WM_operator_properties_sanitize when creating RNA buttons. Now, layout
previews are visible in keymap editor too.
For Windows 8.1 and X11 (Linux, BSD) now use the DPI specified by the operating
system, which previously only worked on macOS. For Windows this is handled per
monitor, for X11 this is based on Xft.dpi or xrandr --dpi. This should result
in appropriate font and button sizes by default in most cases.
The UI has been simplified to a single UI Scale factor relative to the automatic
DPI, instead of two DPI and Virtual Pixel Size settings. There is forward and
backwards compatibility for existing user preferences.

A user doesn't want to necessarily create a new Screen only because she
wants a new window.
This patch allows the user to pick the screen to use for the new Window.
If the screen picked is the active one, it duplicates it (as the old
behaviour in Blender).

Basically all this does is drawing layout previews into the opened layout search menu.
https://youtu.be/RHYWtZP7pyA
The previews are drawn using offscreen rendering so they can't use multi-threading (yet!). But that shouldn't be an issue since only a handful of previews are drawn at the same time. Normally we only need to redraw the preview if a screen layout was changed. Would be nice if PreviewImage could store if it supports threaded rendering.
Previews are saved in files, might be useful if you later want to support appending layouts.
Adds a new file screen_draw.c.
Changing virtual pixelsize only had an affect when a second window was open. (Was also possible to trigger update by opening another window.)
Steps to reproduce:
* Change any editor into user preferences *in main window*
* Change virtual pixel size -> nothing happens
Steps to reproduce fixed glitches were:
* Change any editor to be file browser from menu, Ctrl+O *from the file browser area*, Esc -> area reset to what it was before changing to file browser initially
* Ctrl+O from any area, F12, Esc -> returns to initial editor in full-screen (expected is file browser in full-screen)
Fixes T46229
Core of the fix is removing old area from spacedata list when going back to previous area (see ED_area_prevspace -> BKE_spacedata_remove). Also, when creating a new temp area we now don't exit old area anymore (needed so SpaceFile->op is kept, but it also makes sense in general)
Aaand finally removes some ugly hacks.
Tested quite a bit, so I think it's safe to apply (besides of remark below), just would like to get things double checked and confirmed. After all, this full-screen stuff finally starts to feel like it's working :P
Note, there's still a memory leak when quitting Blender with temp area open. Haven't found out how to solve yet, but it's not that important for review anyway.

Opening a tmp window on a 4K display with virtual pixelsize set to double results in a too small window. For Retina this seems to be handled on GHOST level already, so multiply by virtual pixelsize only.
Calling event handling recursively during window live resize is problematic,
the code wasn't designed to do that. Instead postpone event handling until
after live resize.
- Add blentranslation `BLT_*` module.
- moved & split `BLF_translation.h` into (`BLT_translation.h`, `BLT_lang.h`).
- moved `BLF_*_unifont` functions from `blf_translation.c` to new source file `blf_font_i18n.c`.
This basically does the 'timer' part of Jobs system: it sends a given notifier on every timer step.
This is needed for background tasks (not full-fledged jobs, lighter BLI_tasks based) that want to update UI
(like for up-comming new thumbnail handling in filebrowser).
option.
This makes sense, since contexts get created at runtime, there is little
reason to require recompilation for this.
Only works on linux currently, will be doing more OSs later
