atusb/fw/: add SPI block reception
...
This decreases the retrieval time for a frame of 102 bytes from
660 us to 384 us, corresponding to a speed change from about
1.26 Mbps to 2.17 Mbps (102 bytes plus 2 bytes overhead).

atusb/fw/mac.c: remove queued_rx; buffer frames in the MCU instead
...
queued_rx held a frame in the transceiver's receive buffer until we could
transfer it. This may cause frame loss if a new reception begins.
We now retrieve frames from the transceiver immediately and buffer them
in the MCU.

atusb/fw/mac.c: queue frame reception if USB is busy
...
This way we we make sure we retrieve the frame and thus release dynamic
buffer protection (if enabled).

atusb/fw/mac.c: reserved code 0 and added notification of TX completion
...
- mac.c (queued_tx_ack, rx_done, handle_irq): on TX completion, send a
a zero byte on EP 1
- mac.c (handle_irq): don't receive zero-sized frames (they're
malformed anyway), so that size zero can be used to signal TX
completion

libatrf: added HardMAC functions
...
This function set isn't really usable for real communication. Its main
purpose is to help with testing the firmware.
- tools/lib/driver.h (struct atrf_driver): added driver functions for
HardMAC access
- tools/include/atrf.h (atrf_rx_mode, atrf_rx, atrf_tx),
tools/lib/atrf.c: functions to enable/disable HardMAC mode and to
send/receive frames

...
- include/atusb/ep0.h (enum atspi_requests), ep0.c (my_setup): added
new "HardMAC" requests ATUSB_RX_MODE and ATUSB_TX
- mac.h, mac.c: basic "HardMAC" procedure
- board_app.c (INT0_vect): call MAC-specific interrupt handler if
provided
- Makefile (OBJS): added mac.o
