revset: avoid set duplication in roots()

revset: retrieve a bit less parents in roots()

dispatch: add support for statprof as a profiler This can be selected using the config variable profiling.type or the environment variable HGPROF ("ls" for the default, "stat" for statprof).

This patch permits the UI to quiesce SSL verification warnings by adding a configuration entry named reportoldssl to ui.
