devel: Remove SHA1 hashes for distfiles

Log message:
*: Bump PKGREVISION for ghc-9.0.1

Log message:
Update to th-abstraction-0.4.2.0

0.4.2.0 -- 2020-12-30
* Explicitly mark modules as Safe (or Trustworthy for GHC versions
  prior to 8.4).

0.4.1.0 -- 2020-12-09
* Fix a bug in which normalizeDec would give incorrect kind
  annotations to type variables in quoted Decs. normalizeDec now
  leaves the kinds of type variable binders alone.

0.4.0.0 -- 2020-09-29
* Adapt to the TyVarBndr data type gaining a new flag type parameter
  (in template-haskell-2.17.0.0) to represent its specificity:
* Introduce a new Language.Haskell.TH.Datatype.TyVarBndr module that
  defines TyVarBndr_, a backwards-compatible type synonym for
  TyVarBndr, as well as backporting TyVarBndrSpec, TyVarBndrUnit, and
  Specificity. This module also defines other useful functions for
  constructing and manipulating TyVarBndrs.
* The types in Language.Haskell.TH.Datatype now use TyVarBndr_,
  TyVarBndrUnit, and TyVarBndrSpec where appropriate. Technically,
  this is not a breaking change, since all three are simple type
  synonyms around TyVarBndr, but it is likely that you will need to
  update your th-abstraction-using code anyway if it involves a
  TyVarBndr-consuming function.

0.3.2.0 -- 2020-02-06
* Support substituting into and extracting free variables from
  ForallVisTs on template-haskell-2.16.0.0 (GHC 8.10) or later.
* Fix a bug in which freeVariables could report duplicate kind
  variables when they occur in the kinds of the type variable binders
  in a ForallT.
* Fix a bug in which resolveInfixT would not resolve UInfixTs
  occurring in the kinds of type variable binders in a ForallT.
* Fix a bug in which the TypeSubstitution ConstructorInfo instance
  would not detect free kind variables in the constructorVars.

Log message:
(*/hs-*) BUILDLINK_API_DEPENDS.ghc <8.10, again

Log message:
(*/hs-*) fix build, not adapted to ghc90 version

Log message:
hs-*: add PLIST files

These PLIST files have been autogenerated by mk/haskell.mk using
HS_UPDATE_PLIST=yes during a bulk build.  They will help to track changes
to the packages.  The Haskell packages didn't have PLIST files because
their paths contained package hashes.  These hashes are now determined by
mk/haskell.mk, which makes it easy to generate easy to read PLIST files.

Log message:
Import th-abstraction-0.3.1.0

This package normalizes variations in the interface for inspecting
datatype information via Template Haskell so that packages and support
a single, easier to use informational datatype while supporting many
versions of Template Haskell.
