Merge branch 'op/cvsserver-perl-warning'

Recent versions of Perl started warning against "! A =~ /pattern/"
which does not negate the result of the matching.  As it turns out
that the problematic function is not even called, it was removed.

* op/cvsserver-perl-warning:
  cvsserver: remove unused escapeRefName function
