Some more cleanup, get rid of hack to protect against NULL RNA pointerprops.

Merge branch 'master' into datablock_idprops

Some minor cleanup.

Merge branch 'master' into datablock_idprops

Some cleanup regarding STRUCT_CONTAINS_DATABLOCK_IDPROPERTIES.

This whole system (how to prevent IDP_ID-forbidden structs to get
assigned IDP_ID-allowed IDProps) still seems somewhat brittle to me,
took me some time to wrap my head around it, but... could not find
any better way to do that so far.

Merge branch 'master' into datablock_idprops

Cleanup: Some minor styling.

Merge branch 'master' into datablock_idprops

Add missing handling of sequencer's strips IDProperties.

Cleanup: simpler to define 'no datablock idprop' flag in RNA struct definitions.

That's cleaner & easier to read than to do it for every child class in
register functions...

Merge branch 'master' into datablock_idprops

More cleanup anf fixes!

Merge branch 'master' into datablock_idprops

Fix bunch of missing/incorrect handling of IDProps.

Mainly in readfile.c and library_query.c.
Plus some other minor fixes and cleanup.

Grr, fix stupid typo in previous commit...

Always build before committing :|

Merge branch 'master' into datablock_idprops

Cleanup - resync with master, this needs to be fixed in master first!

Fix another case of bad logic in recurrent function handling IDProps.

And some generic cleanup/styling/etc.

Merge branch 'master' into datablock_idprops

Fix always-unlinking in ID free function.

Since IDProps now handle ID usages, makes sense to pass do_id_user flag
to some new IDP_FreeProperty_ex() as well...
