wireprotoserver: check permissions in main dispatch function The permissions checking code merged from stable is out of place in the refactored hgweb_mod module. This commit moves the main call to wireprotoserver. We still have some lingering code in hgweb_mod. This will get addressed later. Differential Revision: https://phab.mercurial-scm.org/D2717
