Remove read instances from our Haskell code

It turns out that optimising 'read' derived instances (via -O) for
complex data types (like OpCode, or the various objects) can be slow
to very slow. Disabling such instances results in (time make
$all_our_haskell_binaries) large compile-time savings and also smaller...

Split the OptComplNumeric into integer/float ones

This allows the command completion to treat them as separate option
types; this is not useful in build-bash-completion right now, but
might become so in the future.

Define the actual arguments that are supported by programs

This defines the arguments supported and then modifies the
--help-completion output to include them too.

Support the new option types in build-bash-completion

Beside parsing the arguments as well, we also change the serialisation
format for choices/suggests, to make the Python code simpler.

Add support for arguments in --help-completion

This extends the current option-only support with support for
arguments too. They are serialised without a without the prefix (so
just with the type) and the min/max ranges (max="none" for unlimited).

A few new option types have been added as well....

Add a data type for completion information

This can be used for either option or argument completion (although
OptComplNone doesn't make sense for an argument :).

Annotate options with completion information

This is a quite boring patch, just adding annotation information to
all existing options. Some of the annotations are not very good; but
we don't have support for more precise completion in
build-bash-completion, so this is good enough....

Add option for displaying completion information

This patch adds support for a --help-completion option, which will
display the defined options and their completion information, in a
format designed to be parsed easily from Python, for integration into

Rework CLI modules and tests

While investigating how we could test the Daemon.hs module, I realised
that we have a very, erm, sub-optimal situation:

- HTools/CLI.hs has a nice IO/pure separation testing in cmdline
parsing, which allows some basic functionality to be tested, but...

Further hlint fixes

Commit 2cdaf22, “Re-enable standard hlint warnings”, got it almost
right. The only problem is that (confusingly) the default set of hints
is not in HLint.Default, but in HLint.HLint (it includes Default and
some built-ins).

After changing the lint file to correctly include the defaults, we had...
