* Add new flag '-c' that makes 0xFFFF run as a shell
* Split the connect_via_usb() code from main()
* Add console handler for shell like usage of the flasher
- The new function works like the old rf_extract one, no parameters has
changed.
- Now a complete dump/restore will be possible.
- Check for badblocks while copying data
- Shows information about the partition
* Better use of query_error_message() for debugging
adds support for setting and clearing the rd flags (no-retu-watchdog,
serial-console and the like).
The interface to it is a bit cryptic (construct your own hex number) but
it works like like 'chmod'.
1) name the simple functions get_foo and set_foo (and make them more
consistent e.g. set_rd_mode and get_rd_mode).
2) moved remaining simple queries from main.c into query.c
3) created separate query.h header and included it in main.c
4) implemented get_usb_mode (they do not have this in the proprietary
flasher) and added this function to a normal run (-> you will see the
current USB mode when running with -i)
