I've started with the backport of the bytearray type in a new branch

  svn+ssh://pythondev@svn.python.org/python/branches/trunk-bytearray

Any help is appreciated. I already solved most issues.

Open tasks:

 * fix bytearray.extend()

 * add PyString support to bytearray.fromhex

 * Add old style char buffer interface to bytearray (for codecs)

 * Add old style read write buffer interface to bytearray (for
file.readinto)

 * Fix pickle and copy support for bytearray
