To align with what is done by the in-kernel PM, update userspace pm
subflow selftests, by sending the a remove_addrs command together

BusyBox's 'cmp' command doesn't support the '--bytes' parameter.
Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:
cmp: unrecognized option '--bytes=1024'
BusyBox v1.35.0 () multi-call binary.
Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]
Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.
Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.

management suboption handling; this patch adds new mibs for ADD_ADDR

Most of the code had an issue according to ShellCheck.
That's mainly due to the fact it incorrectly believes most of the code
was unreachable because it's invoked by variable name, see how the
"tests" array is used.
Once SC2317 has been ignored, three small warnings were still visible:
- SC2155: Declare and assign separately to avoid masking return values.
- SC2046: Quote this to prevent word splitting: can be ignored because
"ip netns pids" can display more than one pid.
- SC2166: Prefer [ p ] || [ q ] as [ p -o q ] is not well defined.
This probably didn't fix any actual issues but it might help spotting
new interesting warnings reported by ShellCheck as just before,
ShellCheck was reporting issues for most lines making it a bit useless.

mptcp_connect tool was printing some duplicated entries when showing how
to use it: -j -l -r
While at it, I also:
- moved the very few entries that were not sorted,
- added -R that was missing since
commit 8a4b910d005d ("mptcp: selftests: add rcvbuf set option"),
- removed the -u parameter that has been removed in
commit f730b65c9d85 ("selftests: mptcp: try to set mptcp ulp mode in different sk states").
No need to backport this, it is just an internal tool used by our
selftests. The help menu is mainly useful for MPTCP kernel devs.

Simply adding a "sleep" before checking something is usually not a good
idea because the time that has been picked can not be enough or too
much. The best is to wait for events with a timeout.
In this selftest, 'sleep 0.5' is used more than 40 times. It is always
used before calling a 'verify_*' function except for this
verify_listener_events which has been added later.
At the end, using all these 'sleep 0.5' seems to work: the slow CIs
don't complain so far. Also because it doesn't take too much time, we
can just add two more 'sleep 0.5' to uniform what is done before calling
a 'verify_*' function. For the same reasons, we can also delay a bigger
refactoring to replace all these 'sleep 0.5' by functions waiting for
events instead of waiting for a fix time and hope for the best.

These 'endpoint' tests from 'mptcp_join.sh' selftest start a transfer in
the background and check the status during this transfer.
Once the expected events have been recorded, there is no reason to wait
for the data transfer to finish. It can be stopped earlier to reduce the
execution time by more than half.
For these tests, the exchanged data were not verified. Errors, if any,
were ignored but that's fine, plenty of other tests are looking at that.
It is then OK to mute stderr now that we are sure errors will be printed
(and still ignored) because the transfer is stopped before the end.

During the cleanup phase, the server pids were killed with a SIGTERM
directly, not using a SIGUSR1 first to quit safely. As a result, this
test was often ending with two error messages:
read: Connection reset by peer
While at it, use a for-loop to terminate all the PIDs the same way.
Also the different files are now removed after having killed the PIDs
using them. It makes more sense to do that in this order.

The definition of 'rndh' was probably copied from one script to another
but some times, 'sec' was not defined, not used and/or not spelled
properly.
Here all the 'rndh' are now defined the same way.

Some variables were set but never used.
This was not causing any issues except adding some confusion and having
shellcheck complaining about them.

A new "sandbox" net namespace is available where no other netfilter
rules have been added.
Use this new netns instead of re-using "ns1" and clean it.

This patch first adds TFO support in mptcp_connect.c.
This can be enabled via a new option: -o MPTFO.
Once enabled, the TCP_FASTOPEN socket option is enabled for the server
side and a sendto() with MSG_FASTOPEN is used instead of a connect() for
the client side.
Note that the first SYN has a limit of bytes it can carry. In other
words, it is allowed to send less data than the provided one. We then
need to track more status info to properly allow the next sendmsg()
starting from the next part of the data to send the rest.
Also in TFO scenarios, we need to completely spool the partially xmitted
buffer -- and account for that -- before starting sendfile/mmap xmit,
otherwise the relevant tests will fail.

The estimated time was supposing the rate was expressed in mibit
(bit * 1024^2) but it is in mbit (bit * 1000^2).
This makes the threshold higher but in a more realistic way to avoid
false positives reported by CI instances.
Before this patch, the thresholds were at 7561/4005ms and now they are
at 7906/4178ms.
While at it, also fix a typo in the linked comment, spotted by Mat.

Not running it from a new netns causes issues if some MPTCP settings are
modified, e.g. if MPTCP is disabled from the sysctl knob, if multiple
addresses are available and added to the MPTCP path-manager, etc.
In these cases, the created connection will not behave as expected, e.g.
unable to create an MPTCP socket, more than one subflow is seen, etc.
A new "sandbox" net namespace is now created and used to run
mptcp_sockopt from this controlled environment.

On slow or busy VM, some test-cases still fail because the
data transfer completes before the endpoint manipulation
actually took effect.
Address the issue by artificially increasing the runtime for
the relevant test-cases.

'time' is the local variable of run_test() function, while 'max_time' is
the local variable of do_transfer() function. So in do_transfer(),
$max_time should be used, not $time.
Please note that here $time == $max_time so the behaviour is not changed
but the right variable is used.

After the previous patches, the MPTCP protocol can generate
fast-closes on both ends of the connection. Rework the relevant
test-case to carefully trigger the fast-close code-path on a
single end at the time, while ensuring than a predictable amount
of data is spooled on both ends.
Additionally add another test-cases for the passive socket
fast-close.
