revlog: introduce a `display_id` property
We currently using the "index file" to identify a revlog in error output. Since
we are about to make the "index file" location more volatile, we need something
better. We move to use the "radix", as it is close to what we currently use.
We could probably do better, as pointed out in the comment, however that would
be a quite detour from my current goal.
Differential Revision: https://phab.mercurial-scm.org/D10579
This tests if hgweb and hgwebdir still work if the REQUEST_URI variable is
no longer passed with the request. Instead, SCRIPT_NAME and PATH_INFO
should be used from d74fc8dec2b4 onward to route the request.
