Fix a typo in cabal-install/bootstrap.sh [ci skip]

This adds support to `cabal init` for selecting the Cabal spec
version (i.e. the `cabal-version:` field) and also takes care
of translating between pre-SPDX and SPDX license ids.

Warn when failing to symlink an exe in new-install

This provides a partial fix/improvement to #5491

Does not warn if the existing symlink already points to the correct location

Partial solution to #5491

Filter out executables from package-id flags

Remove Text from D.Simple

- Add Parsec/Pretty CompilerId instances
- Fix Parsec PackageIdentifier instance (hopefully it wasn't used for
  anything important)

In the course of 4466310e (see #5526) the
`Setup.hs haddock` CLI was extended to allow component ids to be passed
as positional arguments. However, `autoconfUserHooks` which is used in
case of `build-type: Configure` wasn't updated accordingly, and consequently
this caused `new-haddock` to break for packages using `Configure`.

Preprocess cabal-install.cabal

- 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)
