Change type of program options to 'IO [Options]'

Some options have defaults that depend on the environment, and we
could handle these in two ways:

- use a place-holder value (e.g. data X a = Default | Custom a) that
is later read from the environment
- move the options list to IO monad, where it can read the...

Two small logging improvements

The "starting" message is changed to match the Python one, and in case
the preparation fails, we also log the error (beside printing it on
stderr or writing it to the error reporting pipe), as at this time
logging is usually set up....

Switch writing of PID file to new reporting style

Currently, the writing of the PID file uses a "standard" error
reporting: catch exception, transform it into a 'Result' type, leave
handling of that to the caller. However, for daemon startup, we
actually want exceptions to be propagated up until the handler which...

Move and rename BasicTypes.annotateIOError

It turns out that annotateIOError already exists in the standard
library, with a different purpose (this made me waste 10 minutes
trying to understand why the types were wrong…). Let's move this out
of BasicTypes, since it's used only in Daemon.hs, and also rename it....

Switch daemon startup to pipe-based error reporting

This changes the daemon reporting error to the same mechanism as in
Python: use a pipe which is written to from the forked children.

Move preparation steps of confd in prepMain

This does the address parsing earlier, before we fork, for
better/faster error reporting.

Split queryd run into prepare and exec

This will help with the general daemon split of prepare/run, and flag
errors earlier in the startup.

Convert tag objects to a safer type

Currently, we keep information about the "target" of a tag operation
in a data type similar to (TagKind, Maybe String). This is unsafe, as
nothing (at the type level) prevents us from accidentally having
(TagCluster, Just "instance1.example.com"), or (TagInstance, Nothing)....

Switch Luxi TH code from simple to custom fields

This is needed so that we have more flexibility in generating Luxi
serialisation code (deserialisation is still custom). Also, only
exceptions are now using the 'simple' field types, so we might be able
later to convert and remove that TH code as well....
