Prepare RFID compilation in firmware mode

- switch from linked lists to static arrays 
- remove all non-handle dynamic allocations (at the expense of stack)
- declare all proto/reader/asic/layer2 structures as const
- wrap all handle allocations in macros that expand to references to 
  static structures in case of firmware mode
- update copyright notices
- add skeleton code for openpcd-inside-firmware driver
- update TODO with remaining TODO for firmware mode
