Subject: mbuf: Add debugging helpers for allocation

This adds a few helpers for debugging mbuf allocations when running in
debugging mode (lsan, valgrind, etc.)

- We do not want to cache allocations, so always set M_DOFREE to prevent
  us from putting any mbuf in it.
- We want to update the mbuf allocation owner on function call for more
  precise leak reporting.

Based on Jeremy Marchand's fuzzing work.
