Implement opcode summary support

This implements in the Haskell codebase the opcode summary. As opposed
to Python, we always use custom code for formatting, since we don't
want to use dynamic attribute lookup.

To test this properly, we need to change MetaOpCode to record-syntax,...

Log only partial response in Luxi when in debug mode

Currently, we log the entire response (at debug level) in the Luxi
replies. This is not a good idea; the logging library operates on
strings, and as such it will use huge amounts of memory: without debug...

Optimise recursive Query filters

Currently, the And and Or filters use very nice code, e.g. in case of
OrFilter:

any id <$> mapM evaluateFilter flts

However, looking at the memory profiles shows that application of
any/id to monadic values via '<$>' does not work nicely, losing the...

Make Query operators enforce strictness

Currently, the query operators (binop, etc.) create thunks, instead of
forcing the evaluation of the simple boolean results. This results in
higher than needed memory use.

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 'Query.Language.ItemType' in two sub-types

The QR_VIA_OP/QR_VIA_LUXI types in Python are using yet another
validation mode: QR_VIA_OP is the base type, and QR_VIA_LUXI extends
it (when doing luxi queries). But on the wire they have the same
representation....

Fix docstrings for the Filter type

While looking at the opcode docs and clicking accidentally on the
filter type, I saw that the haddock formatting is broken due to
non-escaped use of special chars. Let's convert the ascii-like
formatting to haddock, and have nicer apidoc....

Cleanup THH function use from built module namespace

Currently, THH.hs "injects" into the built code names of library
functions like Text.JSON.makeObj, Ganeti.JSON.fromObj, etc. built
directly from strings, via (e.g.)

varE (mkName "makeObj")

This means that the "makeObj" name must exist in the target module,...

Remove unsafePerformIO usage

We need to change a few things, most importantly CLI options defaults,
but otherwise we already used the path to files from functions which
were already in the I/O monad, so we don't have to change much of the
code flow.

Additionally, Path.hs now has an explicit export list, to stop...
