Move pyrna_set_to_enum_bitmap to bpy_rna.c

Fix docstring and broken logic (inversion between key and value filtering).

Link to valid set values

Merge branch 'master' into tmp-id-users

Correction to last commit and add docstring

Add key and value type filters

allows for eg:

bpy.data.user_map(key_types={'MESH'}, value_types={'OBJECT', 'MATERIAL'})

Without this, return values could get very large.

de-duplicate some checks

Correct docstring.

Edits to the docstring

Add error-checking on PySequence_Fast result.

Rename 'iter' since this is no longer an iterator

Fix leak when wrong args passed

Minor edits, comments, cleanup & style

Merge branch 'master' into tmp-id-users

Address suggestions and comments from review.

Avoid re-creating a pyobject for each and every ID just to check dict key.

Nice hack suggested by Campbell. :)

Move Py-side of 'users of ID' from rna to bpy.

Note that I kept 'user_of_id' in RNA for now (this one is not an issue re looping over whole main),
but not really sure it's that useful in the end, we could just keep the bpy dict generator I guess...

'users of ID' API (from id-remap).

This adds iterator over all (ID) users of a given datablock.
Mostly handy through the associated RNA API.

Note that it also had to fix an issue with RNA using DNA's ListBase struct (this
works OK with py, but breaks with cpp due to missing include - and we do not want to have to
include a DNA header just for that ;) ).
