Using pre-shared keys is usually a bad idea, one should use eg. IKEv2
instead, but one does not always have the choice.
For AES-CBC, the IV must be unpredictable (see NIST SP800-38a Appendix
C) whereas for AES-CTR or AES-GCM, the IV should never be reused with
the same key material (see NIST SP800-38a Appendix B and NIST SP800-38d
section 8).
If one uses pre-shared keys and VPP is restarted, the IV counter
restarts at 0 and the same IVs are generated with the same pre-shared
keys materials.
To fix those issues we follow the recommendation from NIST SP800-38a
and NIST SP800-38d:
- we use a PRNG (not cryptographically secured) to generate IVs to
avoid generating the same IV sequence between VPP restarts. The PRNG is
chosen so that there is a low chance of generating the same sequence
- for AES-CBC, the generated IV is encrypted as part of the message.
This makes the (predictable) PRNG-generated IV unpredictable as it is
encrypted with the secret key
- for AES-CTR and GCM, we use the IV as-is as predictable IVs are fine
Most of the changes in this patch are caused by the need to shoehorn an
additional state of 2 u64 for the PRNG in the 1st cacheline of the SA
object.

Type: fix
API clients can register for peer events (e.g. to be notified when
connection is established). In a multi-worker setup, peer events might
be triggered from a worker thread. In order to send a peer event to the
clients, an API message needs to be allocated and populated.
API messages allocation is only allowed from the main thread. Currently,
the code does not handle the case when a peer event is trying to be sent
from a worker thread. In debug builds, when this happens, it causes
SIGABRT in vl_msg_api_alloc_internal() because assertion "pool == 0 ||
vlib_get_thread_index () == 0" fails. In production builds, when this
happens, it might cause unexplained behavior.
There is a test that is supposed to catch this but all multi-worker
Wireguard tests are currently disabled. This problem is likely to be one
of the reasons they were disabled.
With this fix, when a peer event is triggered from a worker thread,
allocate and send corresponding API message from the main thread using
RPC.

In a case where one pounds on a single kvp in a KVP_AT_BUCKET_LEVEL
table, the code would sporadically return a transitional value (junk)
from a half-deleted kvp. At most, 64-bits worth of the kvp will be
written atomically, so using memset(...) to smear 0xFF's across a kvp
to free it left a lot to be desired.
Performance impact: very mild positive, thanks to FC for doing a
multi-thread host stack perf/scale test.
Added an ASSERT to catch attempts to add a (key,value) pair which
contains the magic "free kvp" value.

Rename unused SESSION_IO_EVT_BUILTIN_TX to SESSION_IO_EVT_TX_MAIN and
leverage it for non-connected udp tx.
Non-connected udp sessions are listeners and are therefore allocated on
main thread. Consequently, whenever session queue node is not polling
main, tx events generated by external applications might be missed or
processed with some delay. To solve this, request that apps use
SESSION_IO_EVT_TX_MAIN tx events as opposed to SESSION_IO_EVT_TX and
send that to first worker as opposed to main.

For non-connected udp, when retrieving the subscriber session to send
the notification, it uses the current worker thread index whereas the
subscriber session is actually on the main thread. Using the worker
thread may cause a crash since the corresponding session may not be
valid in the worker thread context and even if it is valid, it is the
wrong session. This scenario is seen when the application forks
and adds subscribers to the worker thread session.
