context: add "descendant()" to changectx for efficient descendant examination
This patch adds "descendant()", which uses "revlog.descendant()" for
descendant examination, to changectx.
This implementation is more efficient than "new in old.descendants()"
expression, because:
- "changectx.descendants()" creates temporary "changectx" objects,
but "revlog.descendant()" doesn't
"revlog.descendant()" checks only revision numbers of descendants.
- "revlog.descendant()" stops scanning, when scanning of all
revisions less than one of examination target is finished
this can avoid useless scanning in "not descendant" case.
