DHCPv4 aka BOOTP is somewhat awkward. A DHCP client
on an interface must receive DHCP packets to
the broadcast address or to a unicast address.
Apparently before it's been assigned to itself.
Add this new API to allow external DHCP clients
enable the DHCP client detect feature per interface.

This patch fixes two problems:
1. The lease field in the dhcp_compl_event message can include a list of
vl_api_domain_server_t structs, but no memory is allocated for it.
2. The DNS server address is not copied properly, resulting in wrong IP4
addresses in the event message.

When an mfib entry was created with both paths and entry_flags then
the entry flags were being ignored. If there are no paths then the
flags were passed into mfib_table_entry_update, but in the case where
the entry didn't exist and there were paths and flags, the entry was
created within mfib_table_entry_paths_update() which used a default
of MFIB_ENTRY_FLAG_NONE.
Pass the flags through into the mfib_table_entry_paths_update fn. All
existing callers other than the create case will now pass in
MFIB_ENTRY_FLAG_NONE.

trajectory trace has been broken for a while because we used to save the
buffer trajectory in a vector pointed to in opaque2. This does not work
well when opaque2 is copied (eg. because of a clone) as 2 buffers end up
sharing the same vector.
This dedicates a full cacheline in the buffer metadata instead when
trajectory is compiled in. No dynamic allocation, no sharing, no tears.

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

Autoconfigure router advertisements for delegated prefixes.
Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply,
do NOT reset per-delegated-prefix timers. That prevented vpp from
sending a solicit to renew the delegation on time. That, in turn
caused the RA code to send advertisements with valid_time =
preferred_time = 0. That causes almost any downstream client to throw
away its delegated address.

Keep trying even if the interface in question is not "admin-up,
link-up." In real life, it's normal for link autonegotiation to take a
good fraction of a second. The driver layer takes care of packets sent
