hgweb: add support to explicitly access hidden changesets

This changeset adds a "global" `access-hidden` argument to hgweb. This argument
lift the "hidden" filtering. This means the request has access to hidden (eg:
obsolete) changesets. Secret changesets remains filtered.

This feature has multiple applications. The first main use case is to allow the
hgweb interface to display more obsolescence related data, such as the Anton
Shestakov work to add `obslog` support to hgweb.

The second foreseen usecase is support for a `--remote-hidden` argument to `hg
pull` and `hg clone`. This flag will make it possible to retrieve hidden
(typically obsolete) changeset under some conditions. This is useful when
digging up obsolescence history or when doing full mirroring. More on this
feature coming in later changesets.

To avoid exposing information by mistake, access to this feature is currently
controlled with the `experimental.server.allow-hidden-access` config option. The
option works the same way as `web.allow-push`. The current default is to not
allow any hidden access. However we might change it before the feature stop
being experimental.
