statichttprepo: use new functions for requirements validation

The new code in localrepo for requirements gathering and validation
is more robust than scmutil.readrequires(). Let's port statichttprepo
to it.

Since scmutil.readrequires() is no longer used, it has been removed.

It is possible extensions were monkeypatching this to supplement the
set of supported requirements. But the proper way to do that is to
register a featuresetupfuncs. I'm comfortable forcing the API break
because featuresetupfuncs is more robust and has been supported for
a while.

.. api::

   ``scmutil.readrequires()`` has been removed.

   Use ``localrepo.featuresetupfuncs`` to register new repository
   requirements.

   Use ``localrepo.ensurerequirementsrecognized()`` to validate them.
