Looks like the fix for #884915 only works with RHEL6. Make it work
correctly on Fedora 16.

This adds a patch to fix the broken eventlet code that's installed in the
virtualenv.

Added a flag to run_tests.sh to allow user to optionally install venv with --no-site-packages.

When you create a virtualenv, pip and setuptools/distribute is
installed.
When we later run install_venv.py to update the venv, we should
be sure to grab the latest versions of pip and distribute otherwise
issues like this one are masked:

... so use the system m2crypto library instead.
M2Crypto won't build on Fedora because of some bizarre differences with
Fedora's OpenSSL headers. I can get it to build by doing e.g.
 $> python ./tools/install_venv.py
 $> cd .nova-venv/build/M2Crypto
 $> for i in SWIG/_ec.i SWIG/_evp.i; do sed -i -e "s/opensslconf/opensslconf-x86_64/" $i ; done
 $> cd -
 $> SWIG_FEATURES=-cpperraswarn ./tools/with_venv.sh pip install M2Crypto
but that's clearly no fun. It should be fine to just use the system
version.

... and use it to install virtualenv with yum if it's not available.

libvirt isn't listed in pip-requires because (a) it's not in PyPi and
(b) you always want to use libvirt's python bindings that matches the
version of libvirt installed on the system.
Currently, running nova-compute in virtualenv fails because libvirt
can't be imported. The --no-site-packages flag is what prevents this.
Everything seems to work fine without it. To verify, try deleting the
no-global-site-packages.txt from your .nova-venv.

Subsequent runs of install_venv.sh should upgrade packages to the
latest available.

We don't need to pass the -E argument since we're already running
inside the virtualenv.

more user-friendly and not depend on PIP while not in the virtual
environment.

Also added some more instructive messages to install_venv.py, because otherwise people that don't know what they're doing will install the wrong pip... i.e. I did :-)

Also adds some tools for dealing with virtualenvs to the tools
directory.
