Subject: [PATCH v8 7/7] TCPCT part 2g: parse cookie pair and 64-bit timestamp

Every bit is sacred.  Use as few bits as possible in tcp_options_received.
Group related timestamp flag bits for cache line memory efficiency.

Fix #define spacing for TCP options.

Define and parse 64-bit timestamp extended option (and minor cleanup).
However, only 32-bits are used at this time (permitted by specification).

Parse cookie pair extended option (previously defined).

Handle header extension.

Fix initialization in tcp_minisocks.

[updated to latest posted internet draft-simpson-tcpct-00]

Requires:
   net: tcp_header_len_th and tcp_option_len_th
   TCPCT part 2f: cleanup tcp_parse_options
