cmdutil: provide a way to report how to continue

checkafterresolved allows Mercurial to suggest what command to
use next. If users try to continue the wrong command, there
wasn't a good way for the command to suggest what to do next.

Split checkmdutil into howtocontinue and checkafterresolved.
Introduce wrongtooltocontinue which handles raising an Abort with
the hint from howtocontinue.

This file contains testcases that tend to be related to the wire protocol part
of largefiles.
