changelog: add a `branch` method, bypassing changectx

The only way to access the branch of a changeset is currently to
create a changectx object and access its `branch()` method. Creating
a new Python object is costly and has a huge impact on code doing
heavy access to `branch()` (like branchmap).

This change introduces a new method on changelog that allows direct
access to the branch of a revision. See the next changeset for impact.

  $ hg init
  $ mkdir a
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ hg ci -m m a

  $ mkdir a b
  $ echo a > a/b
  $ hg ci -Am m
  adding a/b

  $ hg rm a
  removing a/b (glob)
  $ cd b

Relative delete:

  $ hg ci -m m ../a

  $ cd ..
