Set the defer timeout to 2.5 seconds, and only make sure that there's at
least a second of delay between the pfsync packet and the ping packet.
The intent is to allow the test to pass even when there's considerable
jitter on the timing measurement (e.g. when the test runs in a VM, such
as during the CI tests).
Allow the test to run in CI.

Summary:
Three of the pf dummynet tests were using filter rules which matched
both the intended epair interface as well as lo0 which now receives
PFIL_OUT events for messages delivered to the local network stack (if
enabled). This commit changes the rules to match only for the expected
epair interface.

Redirect rules use PFIL_IN and PFIL_OUT events to allow packet filter
rules to change the destination address and port for a connection.
Typically, the rule triggers on an input event when a packet is received
by a router and the destination address and/or port is changed to
implement the redirect. When a reply packet on this connection is output
to the network, the rule triggers again, reversing the modification.
When the connection is initiated on the same host as the packet filter,
it is initially output via lo0 which queues it for input processing.
This causes an input event on the lo0 interface, allowing redirect
processing to rewrite the destination and create state for the
connection. However, when the reply is received, no corresponding output
event is generated; instead, the packet is delivered to the higher level
protocol (e.g. tcp or udp) without reversing the redirect, the reply is
not matched to the connection and the packet is dropped (for tcp, a
connection reset is also sent).
This commit fixes the problem by adding a second packet filter call in
the input path. The second call happens right before the handoff to
higher level processing and provides the missing output event to allow
the redirect's reply processing to perform its rewrite. This extra
processing is disabled by default and can be enabled using pfilctl:
pfilctl link -o pf:default-out inet-local
pfilctl link -o pf:default-out6 inet6-local

Rename the jails used in the unicast_ll_v6 test, to ensure the jail
names are unique to this test.
That is one of the requirements for running these tests in parallel.
When checking if the state synced over we should look for
198.51.100.254, not 198.51.100.2. The test worked because the incorrect
address is a substring of the correct one, but we should fix it anyway.

Stubbing out the whole file means it has no targets, so recursive makes
fail with "don't know how to make X". We could fix that, but because the
level above is adding it to TESTS_SUBDIRS it'll generate an include line
for the subdirectory in its Kyuafile, which won't work (the problem that
was previously seen on non-aarch64 in CI). Thus we really need to not
even add it to TESTS_SUBDIRS in the first place.

Fixes: 28f66935d4 ("tests: Disable sys/compat32 and sys/compat32/aarch64 tests")
The former has build system issues, with missing Kyuafiles, presumably
due to not using TESTS_SUBDIRS and bsd.test.mk (and possibly some issues
on top of that around TESTSDIR and related variables). The latter has
issues with GCC and cut-down LLVM builds.

One test is suitable to be hooked up to the build, so I've done this
here. The other test lives in tools/regression because failure is a
bit more subjective -- generally, one runs it for some unbounded amount
of time and observe if it eventually exits because two threads acquired
the same mutex.

Setting vlan flags needlessly takes the exclusive VLAN_XLOCK().
If we have stacked vlan devices (i.e. QinQ) and we set vlan flags (e.g.
IFF_PROMISC) we call rtnl_handle_ifevent() to send a notification about
the interface.
This ends up calling SIOCGIFMEDIA, which requires the VLAN_SLOCK().
Trying to take that one with the VLAN_XLOCK() held deadlocks us.
There's no need for the exclusive lock though, as we're only accessing
parent/trunk information, not modifying it, so a shared lock is
sufficient.
While here also add a test case for this issue.

This change adds netlink create/modify/dump interfaces to the `if_clone.c`.
The previous attempt with storing the logic inside `netlink/route/iface_drivers.c`
did not quite work, as, for example, dumping interface-specific state
(like vlan id or vlan parent) required some peeking into the private interfaces.
The new interfaces are added in a compatible way - callers don't have to do anything
unless they are extended with Netlink.

* Automatic test discovery
* Automatic test module loading
* Minimal boiler-plate code in both kernel and userland
* Passing any metadata to the test
* Convenient environment pre-setup using python testing framework
