Update to python-2.7.3

[vbraun]

Python 2.7.2 distutils have a bug on ext4 or other filesystems with sub-second resolution. The result is that some source files are copied unnecessarily. This is somewhat annoying in sage -b.

New spkg at http://boxen.math.washington.edu/home/jdemeyer/spkg/python-2.7.3.p0.spkg

Our setup.py needed some fixes to work with the new python, most notably you need to tell it to have at least one thread. Also fixed some other warts that annoyed me, like the

setup.py:644: UserWarning: could not find dependency <vector> included in /home/vbraun/opt/sage-5.0/local/lib/python/site-packages/Cython/Includes/libcpp/vector.pxd. I will assume it is a system C/C++ header.

I think one doctest may need fixing, I don't have the particular at hand because my work computer is switched off.

That's the one I got in sage-on-gentoo when we did move to 2.7.3. I think that's the exact same value but that's a memory from 3 weeks ago. We also need to check if it is platform dependent.

This is the upstream change http://hg.python.org/releasing/2.7.3/rev/4970fa3c4a0b

On the plus side, its as platform-independent as it was before.

I'll have a look.

Looks good to me. The package works and the changes to setup.py make sense.

Many files in src/ are not world-readable. This should be fixed to be safe.

Permissions fixed.
