Remove obsolete QrViaLuxi type

The actual query definitions are now in Qlang.hs, so let's use the
ItemType from there instead of luxi-defined type (which is also

Remove obsolete conversion function for Luxi TH

Due to the (now removed) custom filter field, we needed a conversion
function. Since now that field is gone, we can move to a simpler Luxi
TH implementation.

Rename Query2.hs to Qlang.hs

While starting to use the new filter types, I realised that what is
currently implemented is the equivalent of `lib/', not
`lib/', since we only deal with data types for now and not the
actual query runtime functionality (RPC, config, etc.)....

Switch Luxi Query operation to use a proper filter

Until now, since we didn't have a proper type for the encoded query
filters, we were ignoring the filters and handled them as null values
(JSNull and respectively ()). With the current Query2 implementation,...

Re-enable standard hlint warnings

Commit 5a1e31b4 (Add infrastructure for, and two extra hlint rules)
was intended to add two extra hlint rules, but I didn't realise at
that time that "--hint" when first used overrides the built-in
lints. As such, since then we were basically running with just those...

Enhance the Luxi interface implementation

This makes the implementation a bit nicer for both for server and
client side: we add a wrapper function with a better result type, and
a few extra functions for building the response.

Add a server-side Luxi implementation

This is a trivial code change, but it allows us to finally test the
send-receive code on both client and server sides via a simple
in-process server.

The unittest works, but it won't handle timeouts very nicely; it will...

Switch the Luxi interface from Strings to ByteStrings

I'm doing this change for future performance optimisations. Currently
we use the Luxi interface just as a client, so not in the hot path,
but when we'll use this as a server interface, we're interested to...

Switch job IDs to numeric

This has been a long-standing cleanup item, which we've always
refrained from doing due to the high estimated effort needed.

In reality, it turned out that after some infrastructure improvements
(the previous patches), the actual job queue-related changes are quite...

htools: abstract function for parsing job ids

Both the job id and submit job result parsing are abstracted into
separate functions, so that later changes are more localised.

Also, this makes submitManyJobs itself easier to read.

Add decoding of Luxi calls and unittests for LuxiOp

This patch adds a hand-coded decoder for LuxiCall arguments, as the
data-structure is not uniform enough for automated generation (even
for the serialisation, we had to add hints for some fields,
de-serialisation is even harder)....

Auto-define a LuxiReq data type

We currently auto-generate a LuxiOp data type, which holds the entire
operation (including parameters). However, having a data type just for
the method call would be useful, so let's change THH to also
defineSADT for the Luxi constructors....

Cleanup hlint errors

First, we update the recommended hlint version to what I used to get a
clean output (1.8.15). Most of the changes are:

- remove unneeded parentheses
- some simplifications (intercalate " " → unwords, maybe … id →
fromMaybe, etc.)
- removal of some duplicate code (in previous patches)...

Adjust htools code to new Luxi argument format

Rename filter and filter_ to qfilter

We currently use 'filter' as the OpCode, QueryRequest and RAPI field
