tcp: Fit struct tcp_conn into a single 64-byte cacheline
...by:
- storing the chained-hash next connection pointer as numeric
reference rather than as pointer
- storing the MSS as 14-bit value, and rounding it
- using only the effective amount of bits needed to store the hash
bucket number
- explicitly limiting window scaling factors to 4-bit values
(maximum factor is 14, from RFC 7323)
- scaling SO_SNDBUF values, and using a 8-bit representation for
the duplicate ACK sequence
- keeping window values unscaled, as received and sent
