Enhanced Os/2 port of cd writing program in DAO mode. 

Changes from original cdrdao and previous builds:
---------------------
- shows progress in window title. This can be switched off by --notitle option.
- manual priority setting by --priority <priority class,priority delta> option.
  default is 3,30
- new option --cutpad that cuts audio tracks instead of padding when it is
  necessary. It is usefull to write audio cd's from mp3 files or any other
  sources in dao mode where padding is necessary without cracks between tracks.
- --skip option - skips (or adds) specifed number of bytes from beginning while
  reading cd. It is usefull to correct offset of your drive like EAC does.
- compiled with the latest paranoia cdda library
- fixed bug in toc reading
- new option --lock - locks specified drives.
- compiled with VAC 3.6.5. So, no more emx runtime is needed.
- Scsi transport is significantly rewritten. It will work only with aspirout 1.1 beta 4 or above.
