General IO File port connectivity

The general IO File port is a little bit more ellaborated than a simple read/write port. It can read bytes from IO registers to output and write bytes from input to IO registers. Also, it can do some bit processing: load bits (from T flag in SREG to output), store bits (from input to T bit in SREG), set IO bits, clear IO bits.
An opcode has to be provided to specify one of the actions that this port is capable of.

The following opcodes are implemented for the IO File general port:
