[OE-core] [PATCH (v2,resend) 0/3] Rework the devshell

[Chris Larson]

From: Chris Larson <chris_larson at mentor.com>

- Adds a utility metaclass for maintaining class registries
- Shifts the handling of spawning a terminal into a new 'terminal' python
 module
- Automatically selects an appropriate terminal based on what you have
 available on your machine
- Still allows manual selection, but in a more convenient way, and falls back
 to auto if you select an invalid or unavailable (not installed) terminal
- Improves how we spawn screen:

 - Shows a warning when spawning it, so do_devshell doesn't appear to hang
 - Spawns a named screen session 'devshell', to avoid confusion when the user
   already has other screen sessions running

Example usage of the new API for others (e.g. patch resolver) to use:

    import oe.terminal
    oe.terminal.run(command, terminal_title, d)
