logcmdutil: hold makefilematcher/makehunksfilter() by changesetpriner (API)

This merges self.matchfn and self.show(matchfn) into self._makefilematcher,
and does the same for hunksfilter. Because changesetprinter seems to have
too many optional arguments, makefilematcher() and makehunksfilter() will
be packed into one object by later patch.
