Move a node-specific function to Query.Node

This shouldn't live in the main Query module, since it's too node
specific.

Implement support for QFF_SPLIT_TIMESTAMP

I am very very unhappy with this patch. We have to do this, in order
to be compatible with the Python code and behaviour, but there's lots
of duplication; both the Python and the Haskell code will need to be
cleaned up and simplified (we don't need QFF_* at all)....

Fix the node powered field

When initially implementing the node query, I thought the 'powered'
field is a representation of the run-time powered status, which would
make its query complex.

In reality, it's a simple config query, which we can support
easily. We also add a small helper, so that we don't hardcode the...

Fixup node disk free/total queries

The disk free/total values are optional ones, wrapped in a Maybe, so
we shouldn't directly serialise them. In order to simplify the
embedded extraction, we add a small helper function.

Fixup node live field names

The String parameter to 'nodeLiveFieldExtract' is the query2 field
name, not the RPC-layer field name. Grrr for not having a real data
type for this.

Furthermore, we add some safety check that we don't return JSNull via
rsNormal…...

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...

Add some unittests for node queries

These new tests check that:

- no known fields return unknown
- any unknown field returns unknown
- the type of the fields is consistent between the getters and the
field definition
- the length of each result row corresponds with the number of fields...

Rename the Qlang and Queryd modules

Per the new query module hierarchy, rename Qlang to Query/Language and
Queryd to Query/Server. This way, all query-related functionality is
now "contained" in the Query/ directory.

Add Query support for Nodes (no filtering, no RPC)

This is the initial support for Query2: basic infrastructure (except
filtering) and node query support (without RPC).

It implements all the fields (tests by comparison with list-fields on
the Python side), except that:...
