relations: Eliminate getrel()

Browse source 
Most uses of getrel() have been replaced by the safer relations_with()
in commit 0c60e57..67b9135, v4.3.27.  Eliminate the remaining ones:

* Convert rela() to use relations_with().  The case of relations to
  self, where the two differ, doesn't occur.  The code becomes more
  easier to understand, even.

* relations_with() is then getrel()'s last user.  Inline.
