ddc028fe18 cdc_acm: turn on UART_TX LED when sending break signals 
Software typically asserts line break for an extended period
(e.g. PuTTY will assert continuously until the next keypress), so
provide feedback via the LED.

Also declare variables used in both tinyusb callback and uart_thread context
as volatile.

af2540b045 cdc_uart: add CTS/RTS configuration options to board_example_config 
For high data rate applications it's desirable to use hardware flow control
to prevent characters getting dropped when faced with the vagaries of RTOS
and kernel latencies. Adding PROBE_UART_HWFC enables the UART's CTS/RTS pins,
and SET_LINE_STATE messages no longer affect the RTS pin.

a7aa0766f0 Make target reset functionality work out-of-the-box (#123) 
* Fix up target reset functionality.

- Correct GPIO direction logic error in `probe_assert_reset`
- Remember to de-assert nRESET on deinit

* board_pico_config: use pin 1 for reset

This pin is normally used for UART debug output, but that is
undocumented. Repurpose it as reset output.

* main: move stdio_uart_init() before DAP_Setup()

When using GP1 as a reset line, this is necessary to overwrite the
stdio function call from reusing the pin as a debug output.

e51647492e cdc_uart: cater for Windows driver deficiencies 
It's possible for the Windows CDC-ACM driver to ignore the IN endpoint
for long periods of time - multiple frames - if the host application
doesn't consume uart RX data. Boost buffer sizes to compensate.

Also prevent usb_thread from potentially being idle for a tick when
there's work to do.

58fa7a14cd Added a custom USB endpoint handler to process commands on a packet basis, as opposed to the byte FIFO employed previously. This allows multiple commmands to be framed correctly, so they can be processed sequentially without losing packets. 
Suspend DAP thread until the end of the USB callback. This prevents the need for continous polling by DAP thread.

ae5bdb082d Reduce SWCLK frequency from SM/2 to SM/4, to reduce dead cycles. 
Also fix divider becoming 0 when extremely high SWCLK frequencies
are requested (this would have been safe but you would get an
extremely slow SWCLK).

491b96c1d4 Update PIO program to pass read/write commands through FIFO 
alongside bit counts. Also, don't return RX data on write commands.
These two changes allow the probe code to return early after
pushing write commands into the FIFO, which improves throughput.
