SVN rev 183316 on 2008-09-23 21:29:22Z by rwatson
Merge r183265 from head to stable/7:
When invoking the udp_send() from udp6_send() due to use of a v6-mapped
IPv4 address, first drop the udbinfo and inpcb locks, which will otherwise
be recursed. This leads to a potential minor race, but is preferable to a
deadlock when acquiring a read lock after a write lock on the inpcb.
