This information is useful for determining where the build products
are placed, so we can, e.g., run the built executables.

This is a global flag, so it can only be specified prior to the
subcommand.  It controls the name of the cabal.project file which
new-build and related commands looks for.

Previously, these flags had no affect on new-build.
Now, they let you specify where the dist-newstyle directory
should go.

Note that if a relative path is provided, it is resolved
relative to the *project root*.  If this is undesirable,
pass an absolute path instead.

Fixes #4127.

Fixes #4133

This adds support for building foreign libraries with a given ABI version on Linux. This is enables foreign libraries to specify ABI compatibility information. This is important since ABI compatibility differs from package release versions.

Two new fields are added: lib-version-info and lib-version-linux. The former accept versions Libtool-style, the latter sets SONAME versions directly. In both cases, appropriate symlinks are installed.

Libtool accepts ABI version data via the -version-info flag, which takes current[:revision[:age]] data. This is then parsed into a major.minor.build version number. We copy this approach so that library versioning may be generalised to other operating systems than Linux.

Add test suite with two basic tests for solver space leaks.

See https://ghc.haskell.org/trac/ghc/ticket/7436#comment:6.

This is an edge case. If there is only ever one choice for the next goal, the
solver never evaluates the conflict count map. Additions to the map create a
growing thunk.

See cabal-testsuite/README.md for a detailed description
of the new architecture.

Previously, the code would unconditionally report that internal
dependencies were satisfiable, even if --exact-configuration was
provided, we're in per-component mode, and the internal lib was
NOT supplied via a --dependency parameter.  Now ./Setup configure
correctly fails at the right stage.

There is a bit of wibbling to do with compatibility package names.
I think I've gotten it right.

Add `--index-state` support to `cabal get`

[skip ci]

Move functions for creating solver HUnit test cases into a new module.

This commit moves the utility functions from
UnitTests.Distribution.Solver.Modular.Solver to a new module,
UnitTests.Distribution.Solver.Modular.DSL.TestCaseUtils.

With this `cabal get` gains the ability to

 a) unpack and update with the .cabal revision which was
    active at the given index-state, as well as

 b) allow to unpack the most recent package version
    (while satisfying imposed version constraints) as of
    the given index-state

The `--index-state` flag can be combined with `--pristine` if only b) is
desired.
