Fix crash when appending workspace

Caused by rB9b1a5b942cdccc.

Fix crash when renaming workspace render layer

PointerRNA.id.data needs to point to the Scene for render-layers. Have
to do lookup in getter here, so we find the scene that contains a render
layer... which is a bit ugly :/

Revert redundant workaround for buffer overflow

This reverts commit 9ddb857c7a9b9ea7ae55ef39879497676d6d8e71.
Should be redundant after rB839bf119c1a774b475.

Better fix for reading fullscreens from old files

Old fix was rBe38481e53b84db. We now solve this in a nicer way by doing
all workspace versioning after lib-linking.

Fix empty default workspace configuration

The default workspace configuration bundled with Blender was supposed to
contain the pre-2.8 default screen-layouts converted to workspaces ("3D
View Full", "Animation", "Compositing", ...). Apparently I committed the
configuration with only one workspace though ("General"), so correcting
now.

Fix crash opening startup.blend as regular .blend (again)

Earlier fix could cause issues and was reverted in rBfc601d8eaa79a7.
Fixed now by avoiding CTX_ call when context hasn't been setup
completely yet.
I think it's fine to assume G.main equals CTX_data_main call at this point.

Fix (harmless) error print with multiple workspaces

Fixes issue reported in https://developer.blender.org/D2451#62155.
Caused by rB8c250c9b73797520.

Fix failing assert on undo

Caused by rB9fa84d640f151 which set the deprecated pointer for forward
compatibility, leading to failling assertion of this pointer being NULL.
We now NULL the pointer again after writing to file.
