HACK: always use the USART interrupt handler of mode_cardemu()
...
This must be fixed in a way that the per-configuration interrupt
handler is called, depending on the USB configuration that is set.

This makes debug printf's twice as fast (half as slow) and thus

It's always more important to pull out a received character from

card_emu: Only transmit NULL byte from the right state
...
The reader cannot accept a waiting time extension at any time. Rather,
it can only accept it if it is currently waiting for a procedure byte.

mode_cardemu: Disable UART TXRDY generation if we don't have data to TX
...
When the ISO7816 state machine requires us to transmit something, but
we don't have data ready to transmit, we should switch off TXRDY
interrupt generation.
What's missing is of course the other part that re-enabls TXRDY
generation once new data is available

This also removes the actual queuing code from req_ctx, and
leaves this to the caller. Only tw out of the existing states actually
required the ordering requirement enforced by the qeue, and in the
future we will need to have per-endpoint queues anyway. Both means it
is better to manage queues outside the req_ctx, and leve that as a pure
memory allocator.

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.
