absorb: import extension from Facebook's hg-experimental

absorb is a wicked-fast command to use blame information to
automatically amend edits to the correct draft revision. Originally
written by Jun Wu, this import is hgext3rd/absorb/__init__.py with:
 * the `testedwith` value changed
 * the linelog import updated
 * some missing configitems registered
 * some imports reordered per check-code.py
 * some missing __future__ imports added per check-code.py
