Move m_freem() from uipc_mbuf.c to subr_mbuf.c so it can take advantage
of the inlines, like its cousin, m_free().  Also, make a small (first
step?) optimisation of m_free() to use the MBP_PERSIST{,ENT} interface
to hold the lock across frees when possible.  The thing is that right
now, we can only do this easily for at most across one mbuf + one
cluster free, as the comment mentions (it also explains why).  Anyway,
some basic tests revealed a 5-10% overall improvement.  Some of the
results can be found here:
