hgweb: change how dispatch path is reported
When I implemented the new request object, I carried forward some
ugly hacks until I could figure out what was happening. One of those
was the handling of PATH_INFO to determine how to route hgweb
requests.
Essentially, if we have PATH_INFO data, we route according to
that. But if we don't, we route by the query string. I question
if we still need to support query string routing. But that's for
another day, I suppose.
In this commit, we clean up the ugly "havepathinfo" hack and
replace it with a "dispatchpath" attribute that can hold None or
empty string to differentiate between the presence of PATH_INFO.
This is still a bit hacky. But at least the request parsing
and routing code is explicit about the meaning now.
