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).
