GHC commit fbe3fe003ac8d4a06 changed the type CodeBuffers
to an unboxed tuple.

Also submitted at https://github.com/well-typed/generics-sop/pull/167

Sadly, `sbv` uses `head` and `tail` in so many places that it would be it be a
major undertaking to expunge them all. For now, I've opted to simply accept the
warning.

This change was brought on by ghc/ghc!8686.

See ghc!9821.

This is one way to fix ghc#23141. It's perhaps not the cleanest way to fix
it (see ghc#23141 (comment 488083)), but a
working build is better than a broken one.

This somehow nudges the solver towards a sane plan for `winery`.

Addresses #77.

Something attempting to build the deprecated uvector library is a sign
that the solver has taken a horribly wrong turn.

Previously futhark would attempt to build against this.

We now add the cabal project fragments in `ci/config.cabal` to the CI
build to ensure that the solver doesn't use ancient, under-constrained
package versions in its plans.

haxl places a constraint on aeson which precludes the use of
th-abstraction-0.5, which then results in the solver instead choosing
aeson-0.9, which results in a broken install plan.

Fixes #23048.

This is to work around an issue where hydra was trying to update the flake.lock to a newer version of nixpkgs.

The patches primarily deal with mtl-2.3.1 issues, just making consumers
of the package buildable. These were necessary to get some components of
HLS building on GHC 9.6.

During this process it was also discovered that the `vector-space`
package was affected by GHC issue
ghc/ghc#22912 so I've added it to
`extra_packages` in CI.

This commit also includes a small change to the `patch-tool` that fixes
the unpack script in the case that a package which shares a prefix with
the package being upacked is already in the packages dir (e.g. `Chart`
and `Chart-diagrams`).

*  Replaces the Gitlab CI based caching with the cache.zw3rk.com nix binary cache
*  Replaces the niv based input pinning with flakes and flake-compat (to keep the interface the same)
*  Adds the build env to the flake so it can be cached by cache.zw3rk.com
*  Update gitlab job definitions to minimise calls to nix

With:
* c2hs (build_tool_package)
* servant-conduit
* servant-machines
* freer-simple
* linear-generics

This adds patches for freer-simple and servant-*, but adds all 5 to the
CI extra packages

Closes ghc/head.hackage#69
