This fixes #2551.

Several changes here that all go toward replacing the generic HTTP_MALFORMED_FRAME error. It adds 4 new error codes that cover specific error cases already highlighted. Chiefly, it restores the HTTP_FRAME_SIZE_ERROR capability we dropped from HTTP/2, just under a different name.

This PR may trigger the Yet-another-error-code early warning system. However, in practical terms this change reduces the error code space by ~250, based on the fact that en endpoint would do frame length validation of unknown frame types and send an error in such a case.  It also avoids the future complexity required to signal errors on extension frames types above the limit aka the `0xff` problem punt.
