As we can't predict the future, we also place a global upper
bound on the lib:Cabal version we know how to interact with:

The upper bound is computed by incrementing the current major
version twice in order to allow for the current version, as
well as the next adjacent major version (one of which will not
be released, as only "even major" versions of Cabal are
released to Hackage or bundled with proper GHC releases).

For instance, if the current version of cabal-install is an odd
development version, e.g.  Cabal-2.1.0.0, then we impose an
upper bound `setup.Cabal < 2.3`; if `cabal-install` is on a
stable/release even version, e.g. Cabal-2.2.1.0, the upper
bound is `setup.Cabal < 2.4`. This gives us enough flexibility
when dealing with development snapshots of Cabal and cabal-install.

This addresses #415

GHC 8.4.1-rc1 (GHC 8.4.0.20180224) unfortunately still shipped with a
devel snapshot of Cabal-2.1.0.0; but GHC 8.4.1 final will ship w/
lib:Cabal-2.2.0.0

The patch which introduced support for split-sections, 450d6bc4, contained a
cut-and-paste error such that it was controlled by the split-objs flag. Fix
this.

Fixes #5011.

(backported #5165)

The `setup-custom2` tests implicit `setup-depends` which implies
a `Cabal < 2` upper bound, which is incompatible with GHC 8.2 or later

(cherry picked from commit a503345e)

This injects lower-bound constraints on Cabal for custom setup
dependencies to prevent the solver from selecting unsupported
configurations.

Previously we already added an absolute lower bound `Cabal >= 1.20`
for nix-local builds, as that's the minimum version we need to be able
to interact with custom Setup.hs scripts. This refines with logic by
restricting that lower bound even more based on GHC version.

This patch augments this with the following rules:

- GHC 8.4+   constrains  Cabal >= 2.2
- GHC 8.2    constrains  Cabal >= 2.0
- GHC 8.0    constrains  Cabal >= 1.24
- GHC 7.10   constrains  Cabal >= 1.22
- (default   constraint  Cabal >= 1.20)

This only affects nix-style local builds codepaths.
