[PATCH 02/16] Add a "context" argument to add_setshow_enum_cmd

This adds a "context" argument to add_setshow_enum_cmd. Now
add_setshow_enum_cmd will call set_cmd_context on both of the new
commands. This is used in a later patch.

* cli/cli-decode.c (add_setshow_enum_cmd): Add "context"
argument. Call set_cmd_context.
