ancestor: use absolute_import

A few months ago, import-checker.py was taught to enforce a more
well-defined import style for files with absolute_import. However,
we stopped short of actually converting source files to use
absolute_import because of problems with certain files.

Investigation revealed the following problems with switching to
absolute_import universally:

1) import cycles result in import failure on Python 2.6
2) undetermined way to import C/pure modules

While these problems need to be solved, they can be put off.
This patch starts a series of converting files to absolute_import
that won't exhibit any of the aforementioned problems.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
