Patch tested by compiling with `__attribute__ ((format (printf, 2, 3)))`
applied to `cmd_results_new`.
String usage constants have been converted from pointers to arrays when
encountered. General handler format strings were sometimes modified to
include the old input string, especially for unknown command errors.
Implements toggling input events during runtime. This will not attempt
to toggle to a mode that is not supported by the device.
When toggling the wildcard input, the device specific input configs are
altered. Each device will cycle one supported mode.
