- set buffermode off by default
- clear page counter during init and sane_start()
- eject previous page during init and sane_start()
- improved SSM_BUFF macros
- moved set_window() to after ssm-*()
- add coarse calibration (AFE offset/gain & per-channel exposure)
- add fine calibration (per-cell offset/gain)
- free image and fine cal buffers in sane_close()
- compare page counter of small scanners only in non-buffered mode
- add back-side gray mirroring code for DR-2580C
- rewrite all image data processing code
- handle more image interlacing formats
- re-enable binary mode on some scanners
- limit some machines to full-width scanning
* doc/desciptions/canon_dr.desc: v23, improved comments

- add basic support for DR-2580C, DR-2050C, DR-2080C, DR-2510C
- add more unknown setwindow bits
- add support for 16 byte status packets
- clean do_usb_cmd error handling (call reset more often)
- set status packet size from config file
- rewrite config file parsing to reset options after each scanner
- add config options for vendor, model, version
- dont call inquiry if those 3 options are set
