Andres Loeh a551eb62e2 Do the accept check before the body check.
This is a reasonably simple attempt at fixing #460.
By moving the accept check to a place before the body check,
we can make it recoverable (the body check is irreversible,
so everything done after the body check has to fail fatally).

The advantage is that we can now specify routes offering
different content types modularly. Failure to match one
is not fatal, and will result in subsequent routes being
tried.

The disadvantage is that we hereby bump the error priority
of the 406 status code. If a request contains a bad accept
header and a bad body, we now get 406 rather than 400. This
deviates from the HTTP decision diagram we try to follow,
but seems like an acceptable compromise for now.

---
* The `Router` type has been changed. Static router tables should now
be properly shared between requests, drastically increasing the
number of situations where servers will be able to route requests
efficiently. Functions `layout` and `layoutWithContext` have been
added to visualize the router layout for debugging purposes. Test
cases for expected router layouts have been added.
* If an endpoint is discovered to have a non-matching "accept header",
this is now a recoverable rather than a fatal failure, allowing
different endpoints for the same route, but with different content
types to be specified modularly.
* Export `throwError` from module `Servant`
* Add `Handler` type synonym
0.6.1
-----
* If servers use the `BasicAuth` combinator and receive requests with missing or
invalid credentials, the resulting error responses (401 and 403) could be
overwritten by subsequent alternative routes. Now `BasicAuth` uses `FailFatal`
and the error responses can't be overwritten anymore.
0.6
---
* Query parameters that can't be parsed result in a `400` (was `404`).
0.5
---
* Add `Config` machinery (https://github.com/haskell-servant/servant/pull/327).
This is a breaking change, as the signatures of both `route`, `serve` and the
typeclass `HasServer` now take an additional parameter.
* Support for the `HttpVersion`, `IsSecure`, `RemoteHost` and `Vault` combinators
* Drop `EitherT` in favor of `ExceptT`
* Use `http-api-data` instead of `Servant.Common.Text`
* Remove matrix params.
* Remove `RouteMismatch`.
* Redefined constructors of `RouteResult`.
* Added `Delayed` and related functions (`addMethodCheck`, `addAcceptCheck`, `addBodyCheck`, `runDelayed`)
* Added support for Basic Authentication
* Add generalized authentication support via the `AuthServerData` type family and `AuthHandler` handler
0.4.1
-----
* Bump attoparsec upper bound to < 0.14
* Bump wai-app-static upper bound to < 3.2
* Bump either upper bound to < 4.5
0.4
---
* `Delete` now is like `Get`, `Post`, `Put`, and `Patch` and returns a response body
* Add a `RouteMismatch` constructor for arbitrary HTTP response codes (https://github.com/haskell-servant/servant-server/pull/22)
* Add support for the `Patch` combinator
* Support for `Accept`/`Content-type` headers and for the content-type aware combinators in *servant-0.4*
* Export `toApplication` from `Servant.Server` (https://github.com/haskell-servant/servant-server/pull/29)
* Support other Monads than just `EitherT (Int, String) IO` (https://github.com/haskell-servant/servant-server/pull/21)
* Make methods return status code 204 if they return () (https://github.com/haskell-servant/servant-server/issues/28)
* Add server support for response headers
* Use `ServantErr` instead of `(Int,String)` in `EitherT` handlers
* Add `errXXX` functions for HTTP errors with sensible default reason strings
* Add `enter` function for applying natural transformations to handlers
0.2.4
-----
* Added support for matrix parameters, see e.g. http://www.w3.org/DesignIssues/MatrixURIs.html
* Add support for serializing based on Accept header
(https://github.com/haskell-servant/servant-server/issues/9)
* Ignore trailing slashes
(https://github.com/haskell-servant/servant-server/issues/5)
0.2.3
-----
* Fix consuming request body issue
(https://github.com/haskell-servant/servant/issues/3)
* Make code sample in Servant.Server complete
