The root cause of the intermittent span test failures has been
identified as a race between sending the packet and starting the bpf
capture.
This is now resolved, so the test can be re-enabled.

The Sniffer class is often used by test tools such as pft_ping to verify
that packets actually get sent where they're expected.
It starts a background thread to capture packets, but this thread needs
some time to start, leading to intermittent test failures when the
capture doesn't start before the relevant packet is sent.
Add a semaphore to ensure the Sniffer constructor doesn't return until
the capture is actually running.

Rather than using a Scapy-based Python script only check if the state
still exists. Scapy tends to be slow to start, it appears because it
lists all interfaces and gets their (IPv6) addresses a couple of times
at startup. This can be sufficient for the ICMP state to time out and
the test to fail.
We now only check if the state exists or is removed as expected, which
makes things faster, and should mean the test is more robust on slower
machines (such as CI VMs).

When yield a.k.a "generator" iterator is used we need to return all
data using "yield", before returning from the function.
Because of that only encryption tests were run for AES-CBC, other modes
were affected as well.
Add one more loop to the iterator "next" routine to fix that.
This unveiled a problem in the GCM AEAD parser logic, which didn't
correctly handle tests cases with empty plaintext, i.e. AAD only.
Include the fix in this patch as it's a rather trivial one.

When the tunneled (IPv6) traffic had traffic class bits set (but only >=
16) the packet got lost on the receive side.
This happened because the address family check in ovpn_get_af() failed
to mask correctly, so the version check didn't match, causing us to drop
the packet.
While here also extend the existing 6-in-6 test case to trigger this
issue.

With _RB_DIAGNOSTIC defined, provide an RB_RANK method to compute the
rank of a node in an rb-tree, if the subtree rooted at that node is
rank-balanced, and -1 otherwise.
In rb_test, rewrite a bit to avoid malloc/free and nondeterministic
running times because of randomness. Allocate all the nodes on the
stack, and shuffle a set of keys to get randomness for the testing.
Add a rank-balance check for the completed tree.

The test was failing due to the assert on lack of MSG_TRUNC flag in the
output flags of recvmsg().
The code passed MSG_TRUNC, along with sufficient-size buffer to hold the
message to-be-received to the recvmsg(), and expected MSG_TRUNC to be
returned as well.
This is not exactly correct as a) MSG_TRUNC was not even a supported
recvmsg() flag before be1f485d7d and b) it violates POSIX, as
POSIX states it should be set only "If a message is too long to fit in
the supplied buffers,".
The test was working before as the kernel copied input flags to the
output flags. be1f485d7d changed that behaviour to clear MSG_TRUNC
if it was present on the input.
Fix the test by checking POSIX-defined behaviour.
Discussed with: glebius
Implement Linux-variant of MSG_TRUNC input flag used in recv(), recvfrom() and recvmsg().
Posix defines MSG_TRUNC as an output flag, indicating packet/datagram truncation.
Linux extended it a while (~15+ years) ago to act as input flag,
resulting in returning the full packet size regarless of the input
buffer size.
It's a (relatively) popular pattern to do recvmsg( MSG_PEEK | MSG_TRUNC) to get the
packet size, allocate the buffer and issue another call to fetch the packet.
In particular, it's popular in userland netlink code, which is the primary driving factor of this change.
This commit implements the MSG_TRUNC support for SOCK_DGRAM sockets (udp, unix and all soreceive_generic() users).
