[PATCH v2 00/12] Add interface for running pb-plugins

[Samuel Mendoza-Jonas]

With this series Petitboot can discover pb-plugin sources from both
PXE-formatted files and local storage devices, and present them to the user.
>From the new nc-plugin screen the user can request that these plugins be
installed and then run. Changes are made to the UI and process code to allow
processes to be run interactively.

Patches and patch order have changed slightly from v1; notable changes are:
- pb-discover now runs `pb-plugin scan` on each newly discovered storage
  device, and presents these in the UI as well as plugins sourced from the
  network.
- Changes in nc-cui are simplified - 'plugin' type boot_options do not need
  to be handled completely separately from cui_boot_option_add().
- pb-exec now allows the user to optionally drop to a shell after running a
  command.
- A number of minor cleanups, fixes, and improvements.
