cvsserver: Determinize output to combat Perl 5.18 hash randomization
Perl 5.18 randomizes the seed used by its hash function, so iterating through hashes results in different orders from run to run: http://perldoc.perl.org/perl5180delta.html#Hash-overhaul This usually broke t9400 (gitcvs.dbname, gitcvs.ext.dbname, when running cmp on two .sqlite files) and t9402 (check [cvswork3] diff, when running test_cmp on two diffs). To fix this, hide the internal order of hashes with sort when sending output or running database queries. (An alternative workaround is PERL_HASH_SEED=0, but this seems nicer.)
