subrepo: add revdetails() method

This method is able to show the "revision details" for a given revision.
Currently for mercurial subrepos it returns a string which resembles a lot what
the default template writes to the console when doing hg log. For all other
types of subrepos we just return the revision id as a string.

We could not use the templater to get this info because the templater writes to
the console (i.e. it does not return a string that we can use).

This method will be used on the next revision.
