RFC: error code strings

Hi,

Based on feedback from early drafts, we're moving from status codes being
reported as integers to using strings. I'd appreciate early feedback on the
proposed change to the spec. Notably, I'd like to know whether people
prefer the "lower case with spaces" approach or would prefer "EALLSHOUTY"
or "CamelCasedWithNoSpaces"?
