base85: proxy through util module

I'm going to replace hgimporter with a simpler import function, so we can
access to pure/cext modules by name:

  # util.py
  base85 = policy.importmod('base85')  # select pure.base85 or cext.base85

  # cffi/base85.py
  from ..pure.base85 import *  # may re-export pure.base85 functions

This means we'll have to use policy.importmod() function in place of the
standard import statement, but we wouldn't want to write it every place where
C extension modules are used. So this patch makes util host base85 functions.
