Move Described functionality there, out of Cabal the library.
Similarly cabal-install doesn't contain Described instances,
they are only in tests.

Move Cabal instances from cabal-install TreeDiffInstances into it.
Remove defaultToExprViaShow to get better diffs and dumps

Also rename Cabal-QuickCheck (proper case), and add GenericArbitrary
module there.

... which may become a package we upload

Remove unix constraint from cabal.project

(cherry picked from commit 6797a9e5)

- Disable cabal-install's haddock on CI
- Temporarily disable cabal check (`-main-is` in tests)
- Remove this is not a lib note
- Tell to run git update-index --assume-unchanged

    ... when changing to -dev or -monolithic configuration.

    Run --no-assume-unchanged unconditionally, when
    changing to the production build.
- Improve auto-gen note in cabal-install.cabal
- Try to build haddock (with GHC-8.4.3 only)

This script contains similar commands to appveyor.yml, except it relies
on cabal new-build, so should be safe to run locally.

Using this script can ease Travis stress.

ATM I see following tests failing:

- PackageTests/Backpack/Includes3/setup-external-ok.test.hs
    - https://github.com/haskell/cabal/issues/5039
- PackageTests/CustomPlain/setup.test.hs
    - `<command line>: cannot satisfy -package-id Cabal-2.1.0.0-inplace`
- PackageTests/CustomDep/sandbox.test.hs
    - `.../dist-sandbox-3402c05b/setup/setup: createProcess: runInteractiveProcess: exec: permission denied (Permission denied)`

Also undo a change committed by mistake.

The issue is fixed now.

Should unbork the test suite.

This benchmark is based off of a script written by @kosmikus.  It adds
functionality for running multiple trials for each package, but it is currently
missing other features.

See #4462 for the gory details.

Main things about this commit:

- New 'monolithic' flag on cabal-install, which combines
  all of the tests into a single binary.  It's not very
  much code, and you don't pay for any of it on a release
  build.  I quite like it.  The one downside is that
  we can't also pull in Cabal test suites this way.

- Env vars got moved into travis-common.sh

- travis-script.sh now runs the cabal-tests tests, because
  we aren't sending enough build product over to do them
  on the second Travis run

The key idea is that once we put PackageTests in its own package, we can
ensure that its Setup.hs is compiled with the same version of Cabal
library as package-tests is compiled with.  This means that LBI reading
will *always succeed* which is quite nice.
