revset: add extra data to filteredset for better inspection
A filteredset is heavily used, but it cannot provide a printable information
how given set is filtered because a condition is an arbitrary callable object.
This patch adds an optional "condrepr" object that is used only by repr(). To
minimize the maintaining/runtime overhead of "condrepr", its type is overloaded
as follows:
type example
-------- ---------------------------------
tuple ('<not %r>', other)
str '<branch closed>'
callable lambda: '<branch %r>' % sorted(b)
object other
