Once a hop is performed, it will only be re-issued if the z-axis has been
moved in the meantime. Usually it is only moved by a z-homing so doing so
will cause safe_z_home to do the hop on the next homing action.
When z-axis is homed, x and y positions are known. When setting this
boolean option, these are set back to their last positions.
Whenever a hop is specified it is re-issued after the Z axis has been
homed. This is especially necessary when a pressure-based probe is used.
Also, the module decides if a hop is necessary, based on either a known
Z position or a flag that is set whenever the motors are disabled.

The current z_hop support did not work correctly with common slicers
that change Z height between retract and unretract, and it did not
work correctly with slicers that issue a retract at the end of a print
and then at the beginning of the next print.
The z_hop support is therefore being removed until these issues can be
fixed.

Don't default to a Z location of 10, as that could cause damage if the
probe's z_offset is greater than 10. Instead, use the "retract
distance" method that is used for normal multi-sample probing.
Update the PROBE_ACCURACY command parameter names to use the same
parameter names as the PROBE command.

The SET_GCODE_OFFSET command could cause unwanted behavior when an
offset is applied to the following g-code command. (In particular,
when the following command is an extrude only move - as in
issue #1289.)
Don't apply the offset immediately. Instead, add support for a MOVE=1
parameter which will schedule a move to apply the given offset.

Use the field names from the trinamic specification. This makes the
field similar to all the other driver_XXX config options.

The 'bed_shape' option has been removed. The user will enter a 'bed_radius' if they have a round be, otherwise they should enter 'min_point' and 'max_point'. When the bed is round the user should supply a 'round_probe_count' option, otherwise just 'probe_count'.

The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero. A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).
Consistently use 7-bit addresses in all the code. This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.
