Replace hand-coded 'live' field of OpInstanceMigrate

This is the last inline-written field; I've done it separately from
the last patch due to changes being needed in HTools (field changed
type).

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...

Convert a few existing opcode parameters to safer types

This does a partial conversion of existing opcodes to the new
non-empty string type, which is needed so that we don't add even more
opcodes without this safety net (and to have consistent "target_node",...

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....

Create a new Ganeti/Types.hs module

There are already three cases where we copied type definitions between
the htools-specific types into the main ganeti code. Let's stop doing
this ☺ and create a common types module that holds these.

Note that there already exists BasicTypes.hs, but that refers to very...

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,...

Fix two hlint warnings

Sorry, I broke lint again :), by introducing two sub-standard changes.

Additionally, this silences an older existing warning that only
triggers with some versions of hlint (e.g. 1.8.28 which is present in
Wheezy).

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...

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...
