similar: sort files not by object id but by path for stable result

Perhaps the original implementation would want to sort added/removed files
alphabetically, but actually it did sort fctx objects by memory location.

This patch removes the use of set()s in order to preserve the order of
added/removed files. addedfiles.remove() becomes quadratic, but its cost
appears not dominant. Anyway, the quadratic behavior will be eliminated by
the next patch.

Benchmark with 50k added/removed files, on tmpfs:

  $ mkdir src
  $ for n in `seq 0 49`; do
  >     mkdir `printf src/%02d $n`
  > done

  $ for n in `seq 0 49999`; do
  >     f=`printf src/%02d/%05d $(($n/1000)) $n`
  >     dd if=/dev/urandom of=$f bs=8k count=1 status=none
  > done

  $ hg ci -qAm 'add 50k files of random content'
  $ mv src dest

  $ hg addremove --dry-run --time -q

Ensure debuild doesn't run the testsuite, as that could get silly.

We check debian package contents with portable tools so that when
we're on non-debian machines we can still test the packages that are
built using docker.

main deb should have .so but no .py
  $ ar x mercurial_*.deb
  $ tar tf data.tar* | egrep '(localrepo|parsers)'
  ./usr/lib/python2.7/dist-packages/mercurial/parsers*.so (glob)
mercurial-common should have .py but no .so or .pyc
  $ ar x mercurial-common_*.deb
  $ tar tf data.tar* | egrep '(localrepo|parsers)'
  ./usr/lib/python2.7/dist-packages/mercurial/pure/parsers.py
