  * add validation for PatchInfo items, add unit test for parse/unparse
  
  Due to the idiosyncratic format of the PatchInfo on disk (in patch
files and
  inventories), the PatchInfo parser must make certain assumptions regarding
  the PatchInfo items. These are now codified in validation functions and
  enforced when building PatchInfo data. They are also used to provide
correct
  Arbitrary instances for property tests.

So, using unsafPerformIO patchinfo all that time was a mistake, the
correct function to use in reproducible tests should be rawPatchInfo
(slightly ill named function if it is only used in tests..).

You introduce validation functions in Darcs.Patch.Info and then use them
in combination with QuickCheck's `suchThat` function to generate usable
fields for patchinfo's.

Also  no longer used generatore are removed from
D.T.Patch.Arbitrary.RepoPatchV1 .

Good, accepted.
