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.

The max_accel_to_decel variable must not be greater than the max_accel
variable. Make sure to check this when M204 changes max_accel.

Don't require (or permit) the user to specify a stepper_z
position_endstop when using the probe:z_virtual_offset mechanism. In
that case the position_endstop should always equal the probe's
z_offset - so no need to have the user specify it.

Remove the code to calculate and track the z_offset via
position_endstop updates. It's simpler to always save and restore the
calculated z_adjust.

Don't require the config file to specify manual probing. Instead,
allow the user to select manual probing on each ProbePointsHelper
invocation.

Now that all the callers of ProbePointsHelper take a cartesian
coordinate for the probe locations, it's possible to perform averaging
of multi-sample probes within the class. This simplifies the callers.

Only call cmd_NEXT() for manual probing. This simplifies the code as
the automatic probing and manual probing have slightly different
probing mechanisms.

Now that all users of ProbePointsHelper use the same
get_probed_position() code, it is possible to implement that locally
within the ProbePointsHelper class.

It's possible (and a little simpler) to use cartesian coordinates when
calculating a stable position.

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

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.

Don't log a heater verification error if that error is due to the
