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
