* backend/canon_dr.[ch], backend/canon_dr-cmd.h: backend v15 thru v18 

- add byte-oriented duplex interlace code
- add RRGGBB color interlace code
- 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
- remove default config file from code
- add initial gray deinterlacing code for DR-2510C
- rename do_usb_reset to do_usb_clear
* doc/descriptions/canon_dr.desc: backend v18, update model status
* backend/canon_dr.conf.in: added better comments and new options
