largefiles: make archive -S store largefiles instead of standins...

largefiles: make archive -S store largefiles instead of standins This is essentially a copy of largefile's override of archive() in the archival class, adapted for overriding hgsubrepo's archive(). That means decoding isn't taken into consideration, nor is .hg_archival.txt generated (the same goes for regular subrepos). Unlike subrepos, but consistent with largefile's handling of the top repo, ui.progress() is *not* called. This should probably be refactored at some point, but at least this generates the archives properly for now. Previously, the standins were ignored and the largefiles were archived only for the top level repo. Long term, it would probably be most desirable to figure out how to tweak archival's archive() if necessary such that largefiles doesn't need to override it completely just to special case the translating of standins to the real files. Largefiles will already return a context with the true largefiles instead of the standins if lfilesrepo's lfstatus is True- perhaps this can be leveraged?
