Lib relocate/reload: serious rework of code.

Idea here is to both factorize it seriously (reload and relocate are very similar, let's
avoid as much as possible twice the same code...), and make new `lib_relocate_do()`
much more flexible - now it should be able to reload individual IDs as well
(plan is to use it to reload assets in relelvant branch too).

Rework library_query foreach looper - add optional recursivity.

This commit:
* Fixes bad handling of 'stop iteration' (by adding a status flag, so that we can actually
stop in helper functions too, and jumping to a finalize label instead of raw return, to
allow propper clean up).
* Adds optional recursion into 'ID tree' - callback can also decide to exclude current id_pp
from recursion. Note that this implies 'readonly', modifying IDs while recursing is not
something we want to support!
* Changes callback signature/expected behavior: return behavior is now handled through flags,
and 'parent' ID of id_pp is also passed (since it may not always be root id anymore).

Used this new recursive behavior in ID preview generation as an example, would obviously be committed separately.
