Description

The current haskell type mappings are awkward and error prone to work with:

binary -> String
string -> String
byte -> Int
i16 -> Int
i32 -> Int
i64 -> Int

This patch updates the mappings to the canonical types of the correct length in Haskell:

binary -> Data.ByteString.Lazy.ByteString
string -> String
byte -> Data.Word.Word8
i16 -> Data.Int.Int16
i32 -> Data.Int.Int32
i64 -> Data.Int.Int64

THIS BREAKS EXISTING CODE. It is, however, very arguably broken already.

For convenience of patching, this patch is a superset of THRIFT-743.
