Subject:   o use hal to wait-for/mount cdroms:     you can now use more than
 one cdrom drive

big commit, no time to split it... some details:
- split urpm::removable into urpm::removable and urpm::cdrom
- fix setting $urpm->{removable_mounted}
- in try_mounting_non_cdroms(), check for local url, simpler than checking
  is_cdrom_url and then checking file_from_local_medium
- fix _try_mounting_medium() not mounting non-cdrom anymore
  (regression introduced during devel)
- even if urpmi says it wants cdroms in a given order, if you make a mistake,
  it will use the one you give (as a side-effect, it simplifies the sort on
  "already mounted" cdrom (cf _sort_media disappearing))
