 `cabal-install` needs to be able to track all the files it installs so
 that it'll be possible to uninstall packages.

 The copy/install code should be extended to be able to generate a list of
 files and hashes of files that will be installed. `cabal-install` could
 use that to write out a manifest file and use that later to allow
 uninstalling.

 One solution might be to restructure the install code to gather the source
 files that it would install rather than just doing it. Once that list of
 files is known we can copy them all in one go, and do other things like
 check for clashing target files and generate manifests etc.
