arp: Handle initial announcement asynchronously and retry failures.
...
We need to send two ARP announcements, so these are now done via a
timeout callback so that failures can be handled properly.

Handle carrier interruptions in arp_collision_timeout() better.
...
Still not ideal; we need to note and retry these errors, but these
changes are preparatory and do not introduce regressions.

Fix the return values of dhcp_packet_get and arp_packet_get.
...
This corrects a bug where stale dhcp packets would get reprocessed,
causing very bad behavior; an issue that was introduced in the
coroutine conversion.

Use a coroutine instead of several callback state machines.
...
This change makes it much easier to reason about ndhc's behavior
and properly handle errors.
It is a very large changeset, but there is no way to make this
sort of change incrementally. Lease acquisition is tested to
work.
It is highly likely that some bugs were both introduced and
squashed here. Some obvious code cleanups will quickly follow.

Separate event state gathering from action dispatch in main epoll loop.
...
This is the first step towards using coroutines.

Mark pointer arguments that cannot ever be null as [static 1].
...
Also constify some cases, too.

Indicate that client_state_t and client_config_t pointer args
...
cannot ever be null.
Could possibly improve code generation, and makes the intention clear.

Move source from ndhc/ to src/ since ifchd is no longer a separate program.
