scmutil: introduce binnode(ctx) as paired function with intrev(ctx)
It seemed silly to convert ctx.hex() back to binary to use node.hex/short(),
or to use [:12] instead of node.short() because ctx.node() could be None.
Eventually I want to change wctx.rev() and wctx.node() to return wdirrev and
wdirid respectively, but that's quite big API breakage and can't be achieved
without some compatibility wrappers.
