Make orifs behave like a mount command

[Jens Finkhaeuser]

It should work in fstab and/or work with the mount.fuse command.

The main change is to make all options mount options. Luckily, libfuse has option parsing helpers that makes that fairly simple, which also means we could get rid of getopt (for the orifs command at least).

I started a branch for this, will create a pull request when done.

One question about this: are we somehow tied to the specific libfuse version? I'm on 2.9 here, and that seems to be the latest before the 3.x series.

Hmm. I'll also push changes to the man page.

Accepted the diff and I updated the test cases. For now I've cut a new release after a bit of other cleanup and testing. I'm going to try to improve orisync for the next release.
