Modified files:
sys/kern uipc_mbuf.c uipc_socket.c
Log:
Unbreak writes of 0 bytes. Zero byte writes happen when only ancillary
control data but no payload data is passed.
Change m_uiotombuf() to return at least one empty mbuf if the requested
length was zero. Add comment to sosend_dgram and sosend_generic().
