revset: add ^ and ~ operators from parentrevspec extension

^ (Nth parent) and ~ (Nth first ancestor) are infix operators that match
certain ancestors of the set:

  set^0
  the set

  set^1 (also available as set^)
  the first parent of every changeset in set

  set^2
  the second parent of every changeset in set

  set~0
  the set

  set~1
  the first ancestor (i.e. the first parent) of every changeset in set

  set~2
  the second ancestor (i.e. first parent of first parent) of every changeset
  in set

  set~N
  the Nth ancestor (following first parents only) of every changeset in set;
  set~N is equivalent to set^1^1..., with ^1 repeated N times.
