show: Convert show_message to use sprinter

Unlike the previous patches, this function is used for all formats.
However, for formats other than the JSON format, the sprinter methods
used by show_message are all no-ops, so this code continues to
function correctly for all of the formats.

Converting show_message eliminates show_null_message in the process,
since this maps directly to an sprinter method.
