hgweb: rename req to wsgireq We will soon introduce a parsed WSGI request object so we don't have to concern ourselves with low-level WSGI matters. Prepare for multiple request objects by renaming the existing one so it is clear it deals with WSGI. We also remove a symbol import to avoid even more naming confusion. # no-check-commit because of some new foo_bar naming that's required Differential Revision: https://phab.mercurial-scm.org/D2732
