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

Instead of all clients directly RR sourcing the entry they are tracking,
use a deidcated 'tracker' object. This tracker object is a entry
delegate and a child of the entry. The clients are then children of the
tracker.
The benefit of this aproach is that each time a new client tracks the
entry it doesn't RR source it. When an entry is sourced all its children
are updated. Thus, new clients tracking an entry is O(n^2). With the
tracker as indirection, the entry is sourced only once.

Type: fix
If a tunnel interface has the crypto alg set on the outbound SA to
IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface,
the attempt to write an ESP trailer on the packet occurs at the
wrong offset and the vnet buffer opaque data is corrupted, which
can result in a SEGV when a subsequent node attempts to use that
data.
When an outbound SA is set on a tunnel interface which has no crypto
alg set, add a node to the ip{4,6}-output feature arcs which drops all
packets leaving that interface instead of adding the node which would
try to encrypt the packets.

- this remove the need to iterate through all state when deleting an SA
- and ensures that if the SA is deleted by the client is remains for use
in any state until that state is also removed.

There's no call for an SPI-0 punt reason with UDP encap, since
it's only with UDP encap that the ambiguity between IKE or IPSEC
occurs (and SPI=0 determines IKE).
Enhance the punt API to dum ponly the reason requested, so a client
can use this as a get-ID API

For tunnel mode, after decryption the buffer length was being adjusted
by adding (iv length + esp header size). Subtract it instead.
Required for BFD to work on an IPsec tunnel interface. BFD verifies
that the amount of received data is the expected size. It drops the
packet if the buffer metadata says that the packet buffer contains
more data than the packet headers say it should.

Crypto algorithms have different requirements on key length. As we do
not support key stretching (eg. PBKDF2), user must provide the exact
key length used by the algorithm.
Failing that means low-level crypto functions might read garbage (eg.
aes128_key_expand() will read 16-bytes, regardless of the key provided
by the user).
