[tcpip] Add faster algorithm for calculating the TCP/IP checksum

The generic TCP/IP checksum implementation requires approximately 10
CPU clocks per byte (as measured using the TSC).  Improve this to
approximately 0.5 CPU clocks per byte by using "lodsl ; adcl" in an
unrolled loop.

[tcpip] Allow for architecture-specific TCP/IP checksum routines

Calculating the TCP/IP checksum on received packets accounts for a
