Cleanup: Strict compiler warning

Blenloader: New API that will be used for blenloader decentralization

Design Task: T76372

This part of a larger refactoring towards a more extensible architecture
in Blender: T75724

The API is defined in `BLO_read_write.h`. It adds the small data structures
`BlendWriter`, `BlendDataReader`, `BlendLibReader` and `BlendExpander`.
Those contain context about the current read/write operation. Furthermore,
it adds many functions with the prefixes `BLO_write_*`, `BLO_read_*` and
`BLO_expand_*`.

Lib linking and expanding will probably be handled by the more generic libquery
system eventually. The corresponding parts of the API can be removed then.

Cleanup: use ED_object_ prefix for constraint functions

- ED_object_constraint_list_from_constraint was get_constraint_lb
- ED_object_constraint_list_from_context was get_active_constraints
- ED_object_constraint_active_get was get_active_constraint
- ED_object_constraint_active_set was ED_object_constraint_set_active

LibOverride: Cleanup: remove useless per-property override flag.

now that we have more 'global' ways to control that, we can save us
quiet a fwe calls....

"fail" -> "undefined behavior"

Cleanup: replace printf with CLOG
