Harald Welte c0bd7f0aaa mode_cardemu: Move GPIO detection to IRQ, use ring buffer for UART RX ...

We don't want to call into the bulk of card_emu.c from interrupt
context, so let's introduce a ring buffer as a softwre-FIFO between
the USART receiving a byte and the processing of that byte in
card_emu.c, which is then performed from the main loop outside
interrupt context.
