Convert opcode TH code to the use of Field type

This makes more explicit the field behaviour - previously an optional
field was detected via a "Maybe" constructor, and an optional one via
a "Just defval" one. With this, field behaviour become more explicit...

htools: small change in error message in THH.hs

We should also display the value we can't parse, otherwise debugging
is very hard.

htools: improvements to JSON deserialisation

This fixes two problems:

- first, when we deserialise a big object, showing its value is not
useful, as it will hide the actual error message
- second, we shouldn't deserialise a container at once, because then...

htools: add new template haskell system

This system based on explicit types instead of ad-hoc rules
(e.g. instead of deducing from "Maybe Int" an optional field, we now
can say explicitly OptionalField ''Int). In the first phase, this will
be used for the equivalent of lib/objects.py, which has slightly...

Adjust htools code to new Luxi argument format

This partially undoes commit 92678b3, more specifically it removes the
Store data type and the associated code, since all Luxi arguments are
now lists.

Furthermore, since the qfilter field on Query is complex (it's...

Haskell support for generic Query in Luxi

Untill now htools did not have support for generic Query in Luxi. This
patch introduces Query as a supported Luxi operation and replaces
QueryNodes, QueryInstances and QueryGroups with Query.

TH simplification for Luxi

This patch simplifies the generation of save constructors for LuxiOp
by always using showJSON over an array of JSValues, instead of having
to pass showJSON in most cases, except the 5-tuple case.

Skip application of 'id' in TH code

This is just beautification when dumping splices to stdout, as ghc
will optimise the 'id' away anyway.

Original generate code:

opToArgs QueryTags kind name = J.showJSON (id kind, id name)

Afterwards:

opToArgs QueryTags kind name = J.showJSON (kind, name)...

Use TemplateHaskell to build the opID function

This replaces the hand-coded opID with one automatically generated

it's done at compilation time as opposed to runtime.
