TCPCT part 1b: generate Responder Cookie secret
Define (missing) hash message size for SHA1.
Define hashing size constants specific to TCP cookies.
Add new function: tcp_cookie_generator().
Maintain global secret values for tcp_cookie_generator().
This is a significantly revised implementation of earlier (15-year-old)
Photuris [RFC-2522] code for the KA9Q cooperative multitasking platform.
Linux RCU technique appears to be well-suited to this application, though
neither of the circular queue items are freed.
These functions will also be used in subsequent patches that implement
additional features.
