c423be28a0 network: introduce TripleSampling= option in CAN section

received bit by majority rule.

This patch adds support for the TripleSampling= option in the [CAN]

c448459d56 networkd: refuse more than 128 NTP servers 
This test case is a bit silly, but it shows that our code is unprepared to
handle so many network servers, with quadratic complexity in various places.
I don't think there are any valid reasons to have hundres of NTP servers
configured, so let's just emit a warning and cut the list short.

95b2903bde tests: shorten the fuzz test case 
The test was failing in Ubuntu CI with a 30s timeout. It makes
sense to keep the file so exercise the set allocation logic, but
we can make it shorter.

5e2a51d588 networkd: use OrderedSets instead of strvs to store lists of domains 
We were already using OrderedSets in the manager object, but strvs in the
configuration parsing code. Using sets gives us better scaling when many
domains are used.

In oss-fuzz #13059 the attached reproducer takes approximately 30.5 s to be
parsed. Converting to sets makes this go down to 10s. This is not _vastly_
faster, but using sets seems like a nicer approach anyway. In particular, we
avoid the quadratic de-unification operation after each addition.

ea53cfd195 shared/calendarspec: do not allocate a big string on stack 
The string can be as long as a logical line in a unit file — so no unlimited,
but quite big. Let's use a normal heap allocation when making a copy.

93b4dab57e networkd: Allow to retain configs even if carrier is lost 
When there is bad link in the network the carrier goes up/down.
This makes networkd stops all the clients and drop config.
But if the remote router/dhcpserver running a prevention
of DHCP Starvation attack or DHCP Flood attack it does not allow
networkd to take a DHCP lease resulting failure in configuration.
This patch allows to keep the client running and keep the conf
also for this scenario.

Closes #9111

a5dfc36ce6 fuzz-unit-file: add one more test case 
There seems to be no error per se. RequiresMountsFor=%s%s%s..%s%s%s is expanded to
RequiresMountsFor=/bin/zsh/bin/zsh/bin/zsh/bin/zsh/..., which takes a bit of time,
and then we iterate over this a few times, creating a hashmap with a hashmap
for each prefix of the path, each with one item pointing back to the original unit.
Takes about 0.8 s on my machine.

e4a71bf36f networkd: Static neighbor support 
When using networkd we currently have no way of ensuring that static
neighbor entries are set when our link comes up. This change adds a new
section to the network definition that allows multiple static neighbors
to be set on a link.
