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...

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...

Move preparation steps of confd in prepMain

This does the address parsing earlier, before we fork, for
better/faster error reporting.

Split queryd run into prepare and exec

This will help with the general daemon split of prepare/run, and flag
errors earlier in the startup.

Rename Confd.hs to Confd/Types.hs

This should be the last module rename, promise!

We rename this to conform to the other hierarchies (e.g. Query), and
to not have both Confd.hs and Confd/*.hs.

Implement base checkFn/prepFn/execFn model for daemons

This mirrors the code in the Python code base, and is required for
clean error reporting during startup.

This patch implements the basic infrastructure; the confd daemon is
not yet modified to take advantage of this, just the types are...

Fix compatibility with newer Haskell libraries

This small patch fixes compatibility with a few newer Haskell libraries:

- base 4.6, included with ghc 7.6, removed the deprecated 'catch'
function from Prelude, so our "import Prelude hiding (catch)" is now...

Convert query path from string errors to GanetiException

This patch converts all the call paths from 'Result' (which contains
just string errors) to 'ErrorResult', which holds
GanetiException-encoded errors. We can now return proper
OpPrereq/OpExec errors to the clients of the luxi/query socket....
