Fix setting of 'failN1' flag for corner case

This patch includes:

  • The 'failN1' flag is now only set if there is strictly less
    memory available than required for failover.
  • Unit tests for that.

Currently, our error monad—Result—has a plain string error type. This

proper error information to Python code, etc.

Split Rpc tests from QC

This required lots of other code moves, so I created it as a

Split out Objects.hs from QC.hs

This is the first file split out from QC.hs - an easy one, since it
has just one test.

The patch changes the way we build hpc excludes, since now we'll have
many modules that need to be excluded, and hpc doesn't seem to be able...

Implement compilation of regexes at creation time

This means that the verification of the correctness of the regex is
done once, at the deserialisation/creation time, as in the Python
code. To do this, we have to change the FilterRegex type from an alias...

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 filtering support in Query

This adds basic infrastructure for filtering (fully functional except,
as usual, for runtime data), and then uses it for node queries.

Since the filtering exports regex matching as an external
functionality, we have to use a regex library. There are many flavours...

Add an Applicative instance for our Result type

This will allow us to run generic computations in an Applicative
context, if a monadic one is not needed (or not applicable due to
class constraints).

Parameterize the Filter type

In preparation for introducing filtering functionality, we convert the
'Filter' type from a '*' kind to a '* -> *' kind.

This allows us to define some general properties for the filter, and
for example introduce later an easy filter compilation, etc....

Implement QueryFields for Nodes

Since we have all the definitions already, we can easily enable

Adding allocList function

This function iterates over the tryMGAlloc function, updates the node
