Switch from -this-package-key to -this-unit-id.
A small cosmetic change, but we have to do a bit of work to
actually support it:
- Cabal submodule update, so that Cabal passes us
-this-unit-id when we ask for it. This includes
a Cabal renaming to be consistent with Unit ID, which
makes ghc-pkg a bit more scrutable.
- Build system is updated to use -this-unit-id rather than
-this-package-key, to avoid deprecation warnings. Needs
a version test so I resurrected the old test we had
(sorry rwbarton!)
- I've *undeprecated* -package-name, so that we are in the same
state as GHC 7.10, since the "correct" flag will have only
entered circulation in GHC 8.0.
- I removed -package-key. Since we didn't deprecate -package-id
I think this should not cause any problems for users; they
can just change their code to use -package-id.
- The package database is indexed by UNIT IDs, not component IDs.
I updated the naming here.
- I dropped the signatures field from ExposedModule; nothing
was using it, and instantiatedWith from the package database
field.
- ghc-pkg was updated to use unit ID nomenclature, I removed
the -package-key flags but I decided not to add any new flags
for now.
