Build with traps on signed overflow
...
This is UB, we should not be doing it, and we can cheaply turn it into
crashes reliably. We would much rather have crashes than the program
doing something silly.
Benchmarks, but i wonder if they are nonsense because they get identical
times across compilers?!

Enable -Werror=switch-enum
...
switch statements must now match all enum values or disable the
warning.
Explicit is good. This has helped us find two bugs, after solving
another one by debugging.
From now on, adding to an enum will raise errors where they are
not explicitly handled, which is good for productivity, and helps
us decide the correct behavior in all usages.
Notably still excluded from this though are the cases where the
warning is disabled by local pragmas.
fromTOML.cc did not build despite a top-level pragma, so I've had
to resort to a makefile solution for that.

Use boost::format from the boost package

Note that this only requires headers from boost so it doesn't add a
runtime dependency.
Also, use Nixpkgs 18.03.

nix-daemon: Use a thread instead of SIGPOLL to catch client disconnects
...
The thread calls poll() to wait until a HUP (or other error event)
happens on the client connection. If so, it sends SIGINT to the main
thread, which is then cleaned up normally. This is much nicer than
messing around with SIGPOLL.
