ipsec: GCM, Anti-replay and ESN fixess
Type: fix
Several Fixes:
1 - Anti-replay did not work with GCM becuase it overwrote the sequence
number in the ESP header. To fix i added the seq num to the per-packet
data so it is preserved
2 - The high sequence number was not byte swapped during ESP encrypt.
3 - openssl engine was the only one to return FAIL_DECRYPT for bad GCM
the others return BAD_HMAC. removed the former
4 - improved tracing to show the low and high seq numbers
5 - documented the anti-replay window checks
6 - fixed scapy patch for ESN support for GCM
7 - tests for anti-reply (w/ and w/o ESN) for each crypto algo
