notes: implement 'git notes copy --stdin'
This implements a mass-copy command that takes a sequence of lines in the format <from-sha1> SP <to-sha1> [ SP <rest> ] LF on stdin, and copies each <from-sha1>'s notes to the <to-sha1>. The <rest> is ignored. The intent, of course, is that this can read the same input that the 'post-rewrite' hook gets. The copy_note() function is exposed for everyone's and in particular the next commit's use.
