Issue #101 and tweak legacy fallback

make sure they are in the paths for the legacy tests (why did it work before).
Let us hope that svn is not in that directory...

   (Fixed unexpected deprecation warning from prombredanne)
Also removed the warning from fallback, only a deprecation warning is issued.
Environment.py whitespacing
Created a specialized command executor for tests in Environment.py
Legacy Test in test_egg_info now supresses the deprecation warning.
PythonPath is now explicitly controlled to allow setup.py test on clean
   python installations.  *Fixes Issue #101*
Moved some dummy svn tests from test_sdist to test_egg_info since
   they are egg_info tests.
Downgraded a with statement in a test since we haven't offically dropped
   2.4 support, however, maybe it is time.
Added a test case to ensure no extranuous output on sdist with a simple
   dummy package without rev ctrl.

Added a test to run egg_info on a dummy SVN package.
Added a second similar test that invokes the legacy code.

replaced fsencode with decode_as_string - decoded utf8 or console input to
decode_as_string should be called on encoded string before joining
BUG_FIX - It would seem that there is a issue wiht the legacy file listing
  which this commit fits.  I have no clue how any of the other stuff would
  had even worked.

Removed verbose warning from svn_utils.py

Add svn test data

Import socket.error so the code throws the correct exception

There's apparently another security issue in the python3 match_hostname code. No CVE has been issued for it yet:

http://bugs.python.org/issue17997#msg194950

This merge includes two commits. The first updates the included match_hostname code to reflect what's in the python-3.3.3 and python-3.4 stdlib (with a minor change to preserve python2 compat). The second commit adds a check for the backports.ssl_match_hostname module from pypi: https://pypi.python.org/pypi/backports.ssl_match_hostname

If the stdlib doesn't have ssl_match_hostname but backports.ssl_match_hostname exists it uses that code. If neither one are present, then it uses the code included in setuptools.

Using backports.ssl_match_hostname helps system packagers and system admins to have a single place to maintain SSL support rather than every package that's copying the match_hostname code. On the other hand, it means that users won't get any fixes before they go into the backports.ssl_match_hostname module. Brandon Rhodes is the owner of that module and Toshio has done the last several releases to make sure that module is current with the match_hostname security issues.
