mq: factor out push conditions checks...

mq: factor out push conditions checks Some extensions (e.g. hgsubversion) completely override push command. Because extensions load order is unspecified, if hgsubversion loads before mq, mq checks about not pushing applied patches will be bypassed. Short of finding a way to fix load order, extracting the checking logic will allow hgsubversion-like extensions to run the check themselves.
