hgweb: fix a bug due to variable name typo It looks like the "sort" query string parameter was not being honored properly. Differential Revision: https://phab.mercurial-scm.org/D2804

hgweb: stop passing req and tmpl into @webcommand functions (API) We have effectively removed all consumers of the old wsgirequest type. The templater can be accessed on the requestcontext passed into the @webcommand function. For the most part, these arguments are unused. They only exist to provide backwards compatibility. And in the case of wsgirequest, use of that object could actively interfere with the new request object. So let's stop passing these objects to @webcommand functions. With this commit, wsgirequest is practically dead from the hgweb WSGI application. There are still some uses in hgwebdir though... .. api:: @webcommand functions now only receive a single argument. The request and templater instances can be accessed via the ``req`` and ``templater`` attributes of the first argument. Note that the request object is different from previous Mercurial releases and consumers of the previous ``req`` 2nd argument will need updating to use the new API.

hgweb: pass modern request type into various webutil functions (API) Our march towards killing wsgirequest continues. .. api:: Various functions in hgweb.webutil now take a modern request object instead of ``wsgirequest``. Differential Revision: https://phab.mercurial-scm.org/D2802

hgweb: don't redundantly pass templater with requestcontext (API) The requestcontenxt has a ``tmpl`` attribute to access the templater. We don't need to pass the templater explicitly when passing a requestcontext instance. .. api:: Various helper functions in hgweb.webutil no longer accept a templater instance. Access the templater through the ``web`` argument instead. Differential Revision: https://phab.mercurial-scm.org/D2801
