The copyright field is free-form so you can list all the copyright
holders. You can use multiple lines. See for example:
http://hackage.haskell.org/packages/archive/bytestring/0.9.0.1/bytestring.cabal

Then for the license, use Other and specify a license file with all the
appropriate license included in it, or refer to the license files of the
various bits.
