We do a chdir() to the NSS database location so that libnssckbi.so
is available when the database is opened. Strip off a sql: prefix
if one is available. This allows the new sqlite format to work.

Add an additional test pass configuring NSS using the sqlite format.
This requires a bit of a hack to pass in the value to python but
it will work for now.

Resolves: #1057650

Protocol is a per-server or Virtual Host setting so I added a new
VH to do TLSv1.2 testing. It isn't as configurable as I'd like
because the port is hardcoded but it'll do for now.

This tests in an in-tree Apache instance using the local libmodnss.so
shared library, so no pre-installation is necessary.

The tests use python-nose and a hacked python-requests library. It is
hacked so I can obtain the negotiated cipher and protocol as well as
pass a few other things into it.

Tests right now are limited to GET requests.

A new user certificate for 'beta' was added to gencert to do pass/fail
access control testing.

The basic process of the tests are:

- run setup.sh which sets up a new instance with createinstance.sh
  and does some variable substitution.
- nosetests -v

I picture multiple test "suites" of different configurations. Right now
there is only one. A template file is provided for each suite.

Tested only on Fedora 20 right now.

request suitable for submission to a 3rd party CA such as Verisign.
