134b4b6a8b firmware: Move more of the USB shutdown control to usb_enable/usb_disable
- make sure USB resources are re-enabled before jumping to bootloader
- make sure all USB resources are disabled prior to jumping to user fw

cea046008f Increase the default flashing area size to 0x2000
This does two things:
- more reasonable default because stock firmware size is larger than
  the previous default
- it will overwrite 0x3fff with 0xff, so that after flashing stock
  firmware the user firmware is automatically disabled

6a5fe581b9 Implement flashing over I2C and user/stock firmware support
I2C register layout changed a bit to make various operations easier
to implement in FW and for the user.

Flashing/debugging tools now share more code. Firmware is now more
configurable (it's now possible to compile-out various features).

Self-testing for column-shorts is implemented.

Firmware is optimized for low power consumption.
