bash, gcc-3.4, python-defaults and python2.3 for testing

[Matthias Klose <doko@cs.tu-berlin.de>]

Please consider the following packages for testing:

- python2.3 2.3.5-1, fixing a security issue which is
  also fixed in 2.3.4-19, removing non DFSG code
  (md5) and removing the profiler code (python-profiler
  currently is in the new queue, but should go to
  testing/non-free as well).

- python-defaults, tighening the dependency to 2.3.5,
  updated FAQ, no code changes.

- gcc-3.4, should be updated, so that the gcc-3.4
  has the fixes from the gcc-3.4 branch up to the
  date we got the fixes from the gcc-3.3 branch in
  gcc-3.3. only "critical" package is libgcc1, which
  didn't change exported symbols compared to the
  current version in testing.

  I'm not planning any further gcc updates, maybe except
  gcj working on mips/mipsel again.

- bash-2.05b-2 (2.05b-2-24 to 2.05b-2-26)
  - debian/skel.bashrc: Quote dircolors invocation (closes: #285840).
    which can lead to some security problems executing this
    code.
  - one readline fix (for the one statically linked to bash).

Thanks, Matthias
