ui/ncurses: Make boot editor API consistent with config & sysinfo screens
The boot-editor API is a little more exposed than it needs to be: the
boot_editor struct does not need to be available to other files, and the
init function and on_exit functions differ from those provided for the
config and sysinfo screens.
This change unifies the boot_editor API with those for the other
screens.

Currently, we talloc_free() the sysinfo and status messages in the

beyond the callback invocation. This change introduces a per-message
talloc context, which these structures are allocated under. This allows
