Changes Header, ReqBody and QueryParam to take a modifier list.
Resolves https://github.com/haskell-servant/servant/issues/856
ResponseHeader story turns to be somewhat ugly, but it can be made
elegant when https://github.com/haskell-servant/servant/issues/841 is
implemnted, then we can omit HList aka Header Heterogenous List
implementation.
- servant-server changes:
Writing server side intepretations is quite simple using
`unfoldRequestArgument`, which makes Header and QueryParam look quite
the same.
`ReqBody` cannot be easily made optional with current design (what that
would mean: No Content-Type Header?), so that dimensions isn't used
there.
- Add HasLink for all the rest ComprehensiveAPI combinators
- Add 'tricky' Header', QueryParam' endpoints to ComprehensiveAPI
- servant-docs: Quick'n'dirty implementation. Don't use modifiers information (yet).
The changelog for `servant` contains changes across core packages,
as we release them as a suite.
Also added links to the GitHub master as we might update entries
for old versions, as changelogs are written by humans.
- Add build-tool-depends, so new-build can use hspec-discover
- Add mtl bounds in tutorial (and dependency on mtl-compact)
- Add extra-source-files to tutorial, so it's buildable from sdist
This commit begins the reorganization of the servant-client project
so as to allow multiple backends, and also begins some much-needed
refactoring of the servant-client code.
