revlog: add support for partial matching of wdir node id

The idea is simple. If the given node id prefix is 'ff...f', add +1 to the
number of matches (e.g. ambiguous if partial + maybewdir > 1).

This patch also fixes id() revset and shortest() template since _partialmatch()
can raise WdirUnsupported exception.
