Andre Oppermann 1ae4d97d51 Use the improved m_uiotombuf() function instead of home grown sosend_copyin() 
to do the userland to kernel copying in sosend_generic() and sosend_dgram().

sosend_copyin() is retained for ZERO_COPY_SOCKETS which are not yet supported
by m_uiotombuf().

Benchmaring shows significant improvements (95% confidence):
 66% less cpu (or 2.9 times better) with new sosend vs. old sosend (non-TSO)
 65% less cpu (or 2.8 times better) with new sosend vs. old sosend (TSO)

(Sender AMD Opteron 852 (2.6GHz) with em(4) PCI-X-133 interface and receiver
DELL Poweredge SC1425 P-IV Xeon 3.2GHz with em(4) LOM connected back to back
at 1000Base-TX full duplex.)
