This patch extends chk_fail_nr to check the MP_FAIL response mibs.
Add a new argument invert for chk_fail_nr to allow it can check the
MP_FAIL TX and RX mibs from the opposite direction.
When the infinite map is received before the MP_FAIL response, the
response will be lost. A '-' can be added into fail_tx or fail_rx to
represent that MP_FAIL response TX or RX can be lost when doing the
checks.

Add the single subflow test case for MP_FAIL, to test the infinite
mapping case. Use the test_linkfail value to make 128KB test files.
Add a new function reset_with_fail(), in it use 'iptables' and 'tc
action pedit' rules to produce the bit flips to trigger the checksum
failures. Set validate_checksum to enable checksums for the MP_FAIL
tests without passing the '-C' argument. Set check_invert flag to
enable the invert bytes check for the output data in check_transfer().
Instead of the file mismatch error, this test prints out the inverted
bytes.
Add a new function pedit_action_pkts() to get the numbers of the packets
edited by the tc pedit actions. Print this numbers to the output.
Also add the needed kernel configures in the selftests config file.

This fixes a few issues reported by ShellCheck:
- SC2068: Double quote array expansions to avoid re-splitting elements.
- SC2206: Quote to prevent word splitting/globbing, or split robustly
with mapfile or read -a.
- SC2166: Prefer [ p ] && [ q ] as [ p -a q ] is not well defined.
- SC2155: Declare and assign separately to avoid masking return values.
- SC2162: read without -r will mangle backslashes.
- SC2219: Instead of 'let expr', prefer (( expr )) .
- SC2181: Check exit code directly with e.g. 'if mycmd;', not indirectly
with $?.
- SC2236: Use -n instead of ! -z.
- SC2004: $/${} is unnecessary on arithmetic variables.
- SC2012: Use find instead of ls to better handle non-alphanumeric
filenames.
- SC2002: Useless cat. Consider 'cmd < file | ..' or 'cmd file | ..'
instead.
SC2086 (Double quotes to prevent globbing and word splitting) is ignored
because it is controlled for the moment and there are too many to
change.
While at it, also fixed the alignment in one comment.

As explained on ShellCheck's wiki [1], it is recommended to avoid
backquotes `...` in favour of parenthesis $(...):
> Backtick command substitution `...` is legacy syntax with several
> issues.
>
> - It has a series of undefined behaviors related to quoting in POSIX.
> - It imposes a custom escaping mode with surprising results.
> - It's exceptionally hard to nest.

Some vars are redefined in different places. Best to avoid this
classical Bash pitfall where variables are accidentally overridden by
other functions because the proper scope has not been defined.
Most issues are with loops: typically 'i' is used in for-loops but if it
is not global, calling a function from a for-loop also doing a for-loop
with the same non local 'i' variable causes troubles because the first
'i' will be assigned to another value. To prevent such issues, the
iterator variable is now declared as local just before the loop. If it
is always done like this, issues are avoided.
To distinct between local and non local variables, all non local ones
are defined at the beginning of the script. The others are now defined
with the "local" keyword.

Running a specific test by giving the ID is often what we want: the CI
reports an issue with the Nth test, it is reproducible with:
./mptcp_join.sh N
But this might not work when there is a need to find which commit has
introduced a regression making a test unstable: failing from time to
time. Indeed, a specific test is not attached to one ID: the ID is in
fact a counter. It means the same test can have a different ID if other
tests have been added/removed before this unstable one.
Remembering the current test can also help listing failed tests at the
end.

Often, it is needed to run one specific test.
There are options to run subgroups of tests but when only one fails, no
need to run all the subgroup. So far, the solution was to edit the
script to comment the tests that are not needed but that's not ideal.
Now, it is possible to run one specific test by giving the ID of the
tests that are going to be validated, e.g.
./mptcp_join.sh 36 37
This is cleaner and saves time.
Technically, the reset* functions now return 0 if the test can be
executed. This naturally creates sections per test in the code which is
also helpful to understand what a test is exactly doing.

When adding a new tests group, it has to be defined in multiple places:
- in the all_tests() function
- in the 'usage()' function
- in the getopts: short option + what to do when the option is used
Because it is easy to forget one of them, it is useful to have to define
them only once.
Note: only using an associative array would simplify the code but the
entries are stored in a hashtable and iterating over the different items
doesn't give the same order as the one used in the declaration of this
array. Because we want to run these tests in the same order as before, a
"simple" array is used first.

In some edge scenarios, an MPTCP subflows can use a local address
mapped by a "implicit" endpoint created by the in-kernel path manager.
Such endpoints presence can be confusing, as it's creation is hard
to track and will prevent the later endpoint creation from the user-space
using the same address.
Define a new endpoint flag to mark implicit endpoints and allow the
user-space to replace implicit them with user-provided data at endpoint
creation time.

The in-kernel MPTCP path manager, when processing the MPTCP_PM_CMD_FLUSH_ADDR
command, generates RM_ADDR events for each known local address. While that
is allowed by the RFC, it makes unpredictable the exact number of RM_ADDR
generated when both ends flush the PM addresses.
This change restricts the RM_ADDR generation to previously explicitly
announced addresses, and adjust the expected results in a bunch of related
self-tests.

But also some global variables changing the behaviour of this selftests

This patch added five more arguments for chk_join_nr(). The default
values of them are all zero.
The first two, csum_ns1 and csum_ns1, are passed to chk_csum_nr(), to
check the mib counters of the checksum errors in ns1 and ns2. A '+'
can be added into this two arguments to represent that multiple
checksum errors are allowed when doing this check. For example,
chk_csum_nr "" +2 +2
indicates that two or more checksum errors are allowed in both ns1 and
ns2.
The remaining two, fail_nr and rst_nr, are passed to chk_fail_nr() and
chk_rst_nr() respectively, to check the sending and receiving mib
counters of MP_FAIL and MP_RST.
Also did some cleanups in chk_fail_nr(), renamed two local variables

This patch added the self test for MP_FASTCLOSE. Reused the argument
addr_nr_ns2 of do_transfer() to pass the extra arguments '-I 2' to
mptcp_connect commands. Then mptcp_connect disconnected the
connections to trigger the MP_FASTCLOSE sending and receiving. Used
chk_fclose_nr to check the MP_FASTCLOSE mibs and used chk_rst_nr to
check the MP_RST mibs. This test used the test_linkfail value to make
1024KB test files.
The output looks like this:

Since commit 2843ff6f36db ("mptcp: remote addresses fullmesh"), an
MPTCP client can attempt creating multiple MPJ subflow simultaneusly.
In such scenario the server, when syncookies are enabled, could end-up
accepting incoming MPJ syn even above the configured subflow limit, as
the such limit can be enforced in a reliable way only after the subflow
creation. In case of syncookie, only after the 3rd ack reception.
As a consequence the related self-tests case sporadically fails, as it
verify that the server always accept the expected number of MPJ syn.
Address the issues relaxing the MPJ syn number constrain. Note that the
check on the accepted number of MPJ 3rd ack still remains intact.

net. Additionally, ipv6 subflows endpoints are created without any

subflows are created all on the same link, leading to expected delays
and sporadic self-tests failures.

MPTCP join self-tests are a bit fragile as they reply on
delays instead of events to catch-up with the expected
sockets states.
Replace the delay with state checking where possible and
reduce the number of sleeps in the most complex scenarios.
This will both reduce the tests run-time and will improve
stability.

Verify that, when multiple endpoints are available, subflows
creation proceed even when the first additional subflow creation
fails - due to packet drop on the relevant link

Include into the path manager status a bitmap tracking the list
of local endpoints still available - not yet used - for the
relevant mptcp socket.
Keep such map updated at endpoint creation/deletion time, so
that we can easily skip already used endpoint at local address
selection time.
The endpoint used by the initial subflow is lazyly accounted at
subflow creation time: the usage bitmap is be up2date before
endpoint selection and we avoid such unneeded task in some relevant
scenarios - e.g. busy servers accepting incoming subflows but
not creating any additional ones nor annuncing additional addresses.
Overall this allows for fair local endpoints usage in case of
subflow failure.
As a side effect, this patch also enforces that each endpoint
is used at most once for each mptcp connection.

In listener_ns, we should pass srv_proto argument to mptcp_connect command,
not cl_proto.
