[RFC/MI] Renumber enum mi_cmd_result

[Keith Seitz <keiths@redhat.com>]

Hi,

I've been looking over Apple's MI changes, so expect to see quite a few
questions/changes/patches/debates/documentation updates/etc in the coming
weeks on MI.

This simple patch renumbers enum mi_cmd_result so that it starts at one
instead of zero. This is necessary because MI_CMD_DONE would be
indistinguishable from an error condition (both would return zero to
catch_errors).

I have run the testsuite before and after this change, and it produces no
differences.

(Okay, this is almost too simple to leave by itself, but, gotta start
somewhere!)

        From Jim Ingham <jingham at apple dot com>:
        * mi-cmds.h (enum mi_cmd_result): Start numbering at one instead
        of zero so that errors can be distinguished from other status
        returns.
