5d3f5e4081 docs: beef up entrypoint documentation page
Let's use the rough categorization of the markdown pages to add basic
sections, via Jeykll templating. Also, add in a couple of additional
links via a JSON array that lists them.

So much web development, so much wow!

e92b60b20f ipv4ll: do not reset conflict counter on restart
Don't reset the conflict counter when trying a new pseudo random
address, so that after trying 10 addresses the londer timeout is used in
accordance with the RFC

6047637645 strv: when growing strv arrays piecemeal actually allocate memory in exponential steps
Let's improve memory allocation for call such as strv_extend() that just
one item to an strv: these are often called in a loop, where they used
to be very ineffecient, since we'd allocate byte-exact space. With this
change let's improve on that, by allocating exponentially by rounding up
to the next exponent of 2. This way we get GREEDY_REALLOC()-like
behaviour without passing around state.

In fact this should be good enough so that we could replace existing
loops around GREEDY_REALLOC() for strv build-up with plain strv_extend()
and get similar behaviour.

resolved, networkd: don't resolve the user if not root
If a daemon is not started as root, most likely it also can't create its
directory and let's not try to resolve the user in that case either.

Create /run/systemd/netif/lldp with tmpfiles.d like other netif directories.

This is also very helpful for preparing a RootImage for the daemons as NSS crud
is not needed.

3295a461b3 network: introduce ifb (Intermediate Functional Block)
Intermediate Functional Block

The Intermediate Functional Block (ifb) pseudo network interface acts as a QoS concentrator for multiple different sources of traffic. Packets from or to other interfaces have to be redirected to it using the mirred action in order to be handled, regularly routed traffic will be dropped. This way, a single stack of qdiscs, classes and filters can be shared between multiple interfaces.

Here's a simple example to feed incoming traffic from multiple interfaces through a Stochastic Fairness Queue (sfq):

(1) # modprobe ifb
(2) # ip link set ifb0 up
(3) # tc qdisc add dev ifb0 root sfq

b069c2a3f2 shared/seccomp: avoid possibly writing bogus errno code in debug log
CID 1409488.

This code was added in 903659e7b2. The change
that is done here is a simple fix to avoid use of a
unitialized/wrongly-initialized variable, but the bigger issue is that nothing
looks at the returned result to distinguish between 0 and a positive return
value.

the interface. If an interface is not managed by networkd, previously,
the foreign configs of the interface was dropped.
