History
silby b09db08f24 Replace a handrolled defrag function with m_defrag. The handrolled 
function couldn't handle chains of > MCLBYTES, and it had a bug which
caused corruption and panics in certain low mbuf situations.

Additionally, change the failure case so that looutput returns ENOBUFS
rather than attempting to pass on non-defragmented mbuf chains.

Finally, remove the printf which would happen every time the low memory
situation occured.  It served no useful purpose other than to clue me
in as to what was causing the panic in question. :)
