[gentoo-soc] [Report 4] layman improvements

[Devan Franchini]

Hello all,

This week, the following progress has been made:

1.) Replaced the standard file opening procedures in layman's code
     with the "with" statement to allow for a more "resource friendly"
     file opening.
2.) Replaced all instances of "subpath" wtih "branch":
     * To reflect the changes made in the repositories.dtd I have
        replaced all instances of branch with subpath.
     * Changes have also been made to the man page to reflect these
       alterations, along with an example of how to make use of the new
       branch xml variable in a custom overlay.
3.) Added module branch support for the following overlay types:
    * Git
    * Mercurial
4.) Added py3.x compatibility for external test code.
5.) Added local file url support for tar overlays:
     * Previously, layman did not support tar overlays that defined their
       source as "file://<location to tar source>", support for this is now
       added.
     * Along with this added support an option for the user to allow layman
       to delete remotely downloaded tar overlays this is because a
       boolean was added to never delete local tar sources.

Goals for next week:
~~~~~~~~~~~~~~~
  * Push out a new release candidate for layman (along with
    possibly a changelog?)
  * Begin migrating from a docstring tests to a full test suite.

To anyone interested the source code and my commits can be found on
git.overlays.gentoo.org/gitweb/[1][1] or on github.com[2] on layman's

  [1][1] Because my main computer has been down I haven't been able
           to push the commits to this repo. My dol-sen should be pushing
           these to this repo some time this upcoming week.
