Optimizadion: Fix performanse issue of UI on some old GPUs.

Apparently the registry is not large enough and the compiler does something bad in indexing the array.

Drag & Drop: Support Open/Link/Append when dropping .blend file

When a .blend file is dropped into Blender a small menu opens.
In that menu the user can choose between three options: Open, Link and Append.

Followup to previous change, reduce number of relations updates

Only tag relations update when new f-curve was allocated. This solves
possible too slow keyframe insertion when doing character animation,
but still does proper relation update when new ID component became
animated.

Depsgraph: Fix missing relation update

The issue was happening when adding animation to properties
which affects different components of IDs.

Reported by Philipp Oeser as part of T56636.

Fix T56636: Custom property cannot be animated

No need to tag object for time update, with new dependency graph
this forces animation to be re-evaluated, which is not something
we want in this instance.

Same patch/solution Philipp Oeser came to as well.

Mark TODO/XXX as solved

We do have proper access to bmain now.

Outliner: drag&drop - separate moving from parenting

Use drag&drop to parent objects in the outliner by holding down shift.
Previously it was easy to accidently parent objects and there was no way to notice it immediatly.

In some views it is possible to parent objects without using shift; should be obvious from context.

GPU: Fix Issue with recursive downsample and Intel HDXXX

This is caused by a driver bug that prevent us from rendering to (or even
binding) a texture mip level that is below GL_TEXTURE_MAX_LEVEL of the
target texture. This is fine in most drivers (and legal AFAIK) but not on
thoses Intels HDXXX + Windows.

As a fix we just put GL_TEXTURE_MAX_LEVEL lower (which is illegal because
it is undefined behaviour), but in practice it works ok and does not
trigger any warnings or errors.

This commit fixes most of the problems encountered on these GPUs (T56668).

Tentative fix for T57066: Daily build of Blend 2.79 crashes on OSX Mojave.

Looks like we need to explicitly set i18n language to default value on
some OSs... Unless that 'need to create new translated-name IDs in
versionning code for startup file' situation is really seldom.

Anyway, hopefully that will fix the crash.

UI: remove mask toolbar, use menus instead

UI: move scrollbars inside region tabs

Prevent G.fileflags changes when WM_OT_save_mainfile() is called from script

This is to solve an issue where a blend file could be compressed
unbeknownst to the artist. This happened in the following situtation:

- Artist edits an uncompressed blend file.
- Some script saves a compressed blendfile to a separate location.
- When the artist saves the file (s)he is editing (File>Save, or Ctrl+S),
it was silently compressed.
