changegroup: assign to proper attribute 0548f696795b accidentally assigned to self.clrevtolocalrev instead of self._clrevtolocalrev. Surprisingly, no tests failed as a result of this mistake. Curious. Differential Revision: https://phab.mercurial-scm.org/D4144

hgweb: catch ParseError that's raised by revset.match() Some queries, like the demonstrated "first(::)", fail earlier than we call mfunc(), and that results in a "500 Internal Server Error". To prevent it, revset.match() also needs to be in a try-except block.

templatekw: deprecate old-style template keyword function (API) .. api:: `f(**kwargs)` style template keyword function is deprecated. Switch to new `(context, mapping)` API by declaring resource requirements. The new-style API will be the default in Mercurial 4.9. See registrar.templatekeyword for details.

hgweb: mark all lambda template keywords as new-style function This is just a temporary workaround, and will be removed in Mercurial 4.9.

hgweb: use registrar to add "motd" template keyword This prepares for deprecation of old-style keyword functions.

fileset: load core predicates directly to symbols dict We no longer have any side effect in loadpredicate().

fileset: turn on listclean conditionally This is just a micro optimization.

changegroup: always use the treemanifest-enabled version of _packmanifests() It works for flat manifests too. We just cannot use cg1 or cg2 if we have subdirectory manifests. Differential Revision: https://phab.mercurial-scm.org/D4124
