Implement proper state machine based on above RFCs. ACKs to SYNs/FINs
are no longer required/tracked. This is more friendly to peers and
accounts for lost packets and retransmits.
This change also means that all traffic is translated and forwarded
while in transitory timeout, which helps delivering e.g. retransmitted
FINs, FINACKs and other messages.
Also support reopening a session in transitory timeout after seeing both
FINs by seeing both SYNs again. This helps quick connection
reestablishment if the peers want to.

If a fragment arrives with fragment offset = 0 and M = 0, it means that
this is actually a complete packet and per RFC 8200, it should be
treated independently from other fragments. This patch does that.
Fragmentation header is stripped and fragment is forwarded irregardles
of other existing reassemblies in case of full reassembly and treated
the same way as regular packet in shallow virtual reassembly.

Put static mappings in flow hash, drop existing hash tables used for
static mappings. Drop refcount variables and use hash table as a single
point of truth. Allow creating a static mapping conflicting with dynamic
mapping, which will take precedence after dynamic mapping is freed, so
that the existing flow can finish transferring data.

Introduce MAX_CPUS parameters to control maximum number of CPUs used by
VPP(s) during testing, with default value 'auto' corresponding to all
CPUs available.
Calculate test CPU requirements by taking into account the number of
workers, so a test requires 1 (main thread) + # of worker CPUs.
When running tests, keep track of both running test jobs (controlled by
TEST_JOBS parameter) and free CPUs. This then causes two limits in the
system - to not exceed number of jobs in parallel but also to not exceed
number of CPUs available.
Skip tests which require more CPUs than are available in system (or more
than MAX_CPUS) and print a warning message.

This module implement Python access to the VPP statistics segment. It
accesses the data structures directly in shared memory.
VPP uses optimistic locking, so data structures may change underneath
us while we are reading. Data is copied out and it's important to
spend as little time as possible "holding the lock".
Counters are stored in VPP as a two dimensional array.
Index by thread and index (typically sw_if_index).
Simple counters count only packets, Combined counters count packets
and octets.
Counters can be accessed in either dimension.
stat['/if/rx'] - returns 2D lists
stat['/if/rx'][0] - returns counters for all interfaces for thread 0
stat['/if/rx'][0][1] - returns counter for interface 1 on thread 0
stat['/if/rx'][0][1]['packets'] - returns the packet counter
for interface 1 on thread 0
stat['/if/rx'][:, 1] - returns the counters for interface 1 on all threads
stat['/if/rx'][:, 1].packets() - returns the packet counters for
interface 1 on all threads
stat['/if/rx'][:, 1].sum_packets() - returns the sum of packet counters for
interface 1 on all threads
stat['/if/rx-miss'][:, 1].sum() - returns the sum of packet counters for
interface 1 on all threads for simple counters

Allow to supply the external VPP worker config for tests which
do not specify the workers config explicitly, and use
the tags infra to flag those that need attention in this configuration.
This commit shows one example use of such a tag, there will be
a separate commit with the rest of the places needing it,
since that change is rather mechanical.
Thus, the assumption is that the test should by default be agnostic
of the VPP configuration, unless it explicitly specifies so.

We have accumulated several scenarios in prod or wishlists
where it would be useful to have a general infra to say yes/no
about a certain test, and potentially make decisions based on that,
for example:
- runs solo (aka 'time-dependent')
- (wishlist) part of quick smoke-test set
- (wishlist) intermittent failure unrelated to timing
- (wishlist) test broken with a multi-worker config in vpp
Refactor the current "run-solo" code to allow for this extension.

Some of the tests are time-sensitive, and at present require a non-trivial
modification in order to run at high concurrency.
Without these modifications, they intermittently fail, and require
the test retries.
Rather than setting them to the extended tests and forgetting
about them, put them into a "solo" set, which gets run in a
single-threaded mode after the rest of the tests are done.
Mark a few of the tests that showed errors during TEST_JOBS=48
as forced-solo.
Also, give a better diagnostic if the testcase misses a docstring
needed to represent it in the diagnostic outputs.

Add a hook to src/vlibapi/api_shared.c to fuzz (screw up) binary API
messages, e.g. by xoring random data into them before processing. We
specifically exempt client connection messages, and inband debug CLI
messages. We step over msg_id, client index, client context, and
sw_if_index. Otherwise, "make test" vectors fail too rapidly to learn
anything.
The goal is to reduce the number of crashes caused to zero. We're
fairly close with this patch.
Add vl_msg_api_max_length(void *mp), which returns the maximum
plausible length for a binary API message.
Use it to hardern vl_api_from_api_to_new_vec(...) which takes an
additional argument - message pointer - so it can verify that
astr->length is sane. If it's not sane, return a u8 *vector of the
form "insane astr->length nnnn\0".
Verify array lengths in vl_api_dhcp6_send_client_message_t_handler(...)
and vl_api_dhcp6_pd_send_client_message_t_handler(...).
Add a fairly effective binary API fuzz hook to the unittest plugin,
and modify the "make test" framework.py to pass "api-fuzz { on|off }"
to enable API fuzzing: "make API_FUZZ=on TEST=xxx test-debug" or similar
