dirstate: add code to update the non-normal set Before this patch, we were only populating the non-normal set when parsing or packing the dirstate. This was not enough to keep the non-normal set up to date at all time as we don't write and read the dirstate whenever a change happens. This patch solves this issue by updating the non-normal set when it should be updated. note: pack_dirstate changes the dmap and we have it keep it unchanged for retrocompatibility so we are forced to recompute the non-normal set after calling it.

dirstate: attach the nonnormalset to a propertycache This patch attaches the nonnormalset to a property cache so that we build it only when needed.

dirstate: add a function to compute non-normal entries from the dmap This patch adds a new python function in the dirstate to compute the set of non-normal files from the dmap. These files are useful to compute the repository status.
