In the rare case where the step generation code finds an interval of
zero, it was possible for an integer division of a negative number to
cause an incorrect result. Fix that by using the idiv_up() and
idiv_down() helpers.

Revert "scripts: Disable "virtualenv setuptools" in install-octopi.sh script"
This reverts commit 5fc92ff6b7.
Revert "scripts: Install "virtualenv setuptools==44.0.0" in install-octopi.sh"
This reverts commit 730c7cfc20.
The online setuptools repository was fixed upstream, so it is no
longer necessary to implement a local virtualenv workaround.

There have been several reports that increasing the delay from 37us to
40us eliminates screen corruption on some clone hd44780 displays.
Increase the timeout value so that the standard code works on these
displays.

The caller can now determine which steppers are connected to cartesian
Z movement via the new stepper.is_active_axis() method. It is
therefore no longer necessary for the kinematic code to identify these
steppers.

In addition to spi3, spi1 and spi2 also have alternate pins. Add them as
spi1a and spi2a, similar to spi3.

The stm32 has a small queue for spi tx/rx. The current code only uses the
spi with a single byte buffer, effectively waiting for each byte to complete
before starting the next transfer.
This patch changes the structure of spi_transfer() to make use of the queue
and achieve back-to-back transfer of bytes on spi.

The current code accesses the DR as 32 bit. This enabled data packing mode,
effectively adding a 00 byte between each sent byte. The receive side had
similar problems.
To prevent this, all accesses are 8 bit now, even though this is not
necessary on stmf[14].

A default config file for Monoprice Mini Delta printers.
Works when firmware is flashed via ST-Link V2 and when a
10A power supply is available. Lots of comments about wanting
to try pressure advance on the FB group, so I figured it was
a good time to get this added.

The default setuptools installed by virtaulenv has dropped support for
python2. Explicitly remove it from the installation.

Move interpolation checks to _init_mesh_params() so they can be done whle the config is being parsed. Do not allow a probe_count higher than 6 for lagrange interpolation, as this typically leads to oscillation.

Don't force probing when BED_MESH_MAP is executed, output the existing mesh. If the user wants to probe each time before a map they can do so with a gcode_macro.

Renamed some variables in set_mesh() previous called "mesh_min" and "mesh_max" to alleviate confusion with the config options.
Renamed several attributes for clarity. The "calibrate" attribute is now bmc, "probe_params" is now "mesh_params", "probed_z_table" is now "probed_matrix", "mesh_z_table" is now "mesh_matrix".

Points are now logged after the printer is ready. The formatting is improved, printing out the point index, and its corresponding automatic and manual points.
BED_MESH_OUTPUT now includes a PGP parameter, if PGP=1 the generated points are printed to the terminal.

Rename min_point, max_point, and bed_radius to mesh_min, mesh_max, and mesh_radius respectively. Add "mesh_origin" option, that allows round beds to specificy the center of the mesh.
