The usb_cdc code will arrange to call usb_read_ep0_setup() after a
shutdown, so no need to have an explicit shutdown handler.

Call usb_read_bulk_out() before calling command_find_and_dispatch() as
this optimizes the common case where each usb packet contains a single
new message block.

Recent code additions have increased the stack usage and it is no
longer clear that everything will fit in 128 bytes. Increase all
targets to 256 bytes (the atmega2560 was already at 256 bytes).

Fix travis-ci build failure by forcing the data field of the struct
usb_string_descriptor to be the same type as a 16bit unicode string.

Use new usb_read_ep0_setup() function when reading a setup packet -
this allows the low-level usb hardware code to better handle errors.

A zero length packet should only be sent at the end of a transmission
if the host is expecting more data.

Maintain the state tracking code entirely within a usb_do_xfer()
method. This simplifies the callers.

Use "ep0" when referring to endpoint0 - don't use "setup" as that can
be confused with the low-level usb setup token.

The atmega168 doesn't have enough flash space to fit all features -
disable the "bit banging" interfaces to make room.

The bank_id was calculated erroneously. Also unify gpio_in_setup and gpio_out_setup a bit. Also disable make flash for the sam4e8e port as it currently references a version of bossac that is not present on all systems.

This can be flashed to e.g. the duet wifi using bossac. It requires a
later version as is currently included in the klipper repo (1.8
vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD

It's common for boards to have restrictions on the type of each
endpoint. So, make it possible for the board to select the endpoint
ids for each endpoint.

No need to include separate cmsis files from the mbed project - the
standard CMSIS_5 files work fine.

Update the sam3x8e port use the most recent SAM3X CMSIS files from
Atmel. The Atmel files appear to have a more consistent license and
it is unclear if there were Arduino specific changes in the CMSIS
files obtained from the Arduino repo.

Send the temperature before checking for an out of range error (that
makes it easier to debug).
The query_thermocouple clock parameter is unpredictable and a value of
zero can't be used to disable the query - use rest_ticks instead.
