[TCP]: Fix excessive stack usage resulting in OOPS with 4KSTACKS.
Various routines were putting a full struct tcp_sock on
the local stack. What they really wanted was a subset
of this information when doing TCP options processing
when we only have a mini-socket (for example in SYN-RECVD
and TIME_WAIT states).
Therefore pull out the needed information into a sub-struct
and use that in the TCP options processing routines.
