[PATCH v3 0/2] oidmap: migrate cleanup to oidmap_clear_with_free()

[Seyi Kuforiji <kuforiji98@gmail.com>]

Hi,

This series replaces oidmap_clear(map, 1) with
oidmap_clear_with_free() and introduces explicit free callbacks
at the remaining call sites.

The old boolean-based API implicitly assumed plain free(),
which obscures ownership semantics and does not work well
when oidmap_entry is embedded inside larger structures.
The callback-based API makes cleanup explicit and type-safe,
and avoids relying on hidden assumptions about allocation.

This is used in subsequent commits to adequately cleanup all
usage site.

Changes in v3:
 - rename funtion to meet guidlines
 - drop [PATCH 3/5]

Thanks
Seyi
