ghc-either-5.0.1.1-bp153.1.20

- Update Cabal file to get more accurate dependency information.

- Drop obsolete group attributes.

- Update either to version 5.0.1.1.
  5.0.1.1 [2019.05.02]
  - -------------------
  * Only incur a `semigroups` dependency on pre-8.0 GHCs.

- Update Cabal build instructions to support ghc-8.6.1.

- Cosmetic: replace tabs with blanks, strip trailing white space,
  and update copyright headers with spec-cleaner.

- Update either to version 5.0.1.
  5.0.1 [2018.07.03]
  - -----------------
  * Make the `Semigroup`, `Apply`, and `Applicative` instances for `Validation`
    lazier.
  * Make `vap` lazier in its second argument.
  * Introduce `vapm`, an even lazier version of `vap` which requires a
    `Monoid` constraint. Also add `apm`, a counterpart for `Validation`.
  * Use `test-framework` and `QuickCheck` in the test suite.

- Update either to version 5.
  * Changed the semantics of the `Validation` `Alt` and `Alternative` instances to collect errors.
    The previous implementation did not correctly abide the laws.
  * Added `vap`, for when users want validation like semantics but don't want to convert back and forth to validation all the time. Similarly, added `ealt` to give either's `Alt` semantics to validation.
  * Dropped the deprecated `Control.Monad.Trans.Either`.  Use `Control.Monad.Trans.Except` from `transformers` and/or
    `transformers-compat` instead.
  * Add `MMonad` instance for `EitherT`
  * Deprecate `Control.Monad.Trans.Either` in favor of `Control.Monad.Trans.Except`
  * Add `firstEitherT`
