Specify hardware pwm cycle times using the same method as software pwm
(in seconds, not clock ticks). Allow the fan code to be configured
with an explicit cycle time even when using software pwm.

If the mcu supports command restarts and it does not appear to use a
real serial port, then default the restart method to 'command'. This
is a better default on boards with native USB support.

Add support for disabling homing checks via the homing_override
mechanism. This may be useful to move an axis prior to homing it.

Create a virtual pin that may be used as the z endstop pin on

Allow a set of g-code scripts to be run on each probe invocation.
This may be useful for probes that need to be setup before they are
useful (eg, with servo actuated probes).

Allow users to override the behavior of G28 using a new
"homing_override" config section. This may be used on printers that
require specific steps during the homing process.

Instead of hardcoding which objects are called on state transitions,
allow any "printer object" to be invoked if it has a printer_state()
method. Convert connect, ready, shutdown, and disconnect callbacks to
this mechanism.
Similarly, allow all printer objects to provide a stats() callback.

Add get_reactor(), lookup_object(), lookup_module_objects(), and
set_rollover_info() to the main Printer class so that callers do not
need to peek into the class' members. Similarly, add get_printer()
and get_name() methods to the ConfigWrapper class.

Use an alpha transparency on each of the stats, so that it is possible
to see how the values overlap.
Also, always enable the "awake time" stat - just use a lower alpha
transparency for it.
Also, explicitly set the graph size as some version of matplotlib have
a different default.

Update the mechanism to filter out cases where buffer_time is below
MAXBUFFER so that it works with the statistics currently generated.

The previous code increases print_stall if a move is proactively
flushed due to buffer_time_low and a follow up move is ready to send
before the existing moves are fully retired. However, this would not
track the case where a move is proactively flushed and it takes an
extended amount of time to get sufficient moves to refill the queue.
Change the code so that print_stall increases anytime a new move is
queued after a proactive flush and there are existing moves not yet
fully retired.

Enable all the steppers via the shift registers when the first stepper
is enabled, and disable all the steppers once all steppers are
disabled. This avoids having to enable all the steppers all of the
time. Note that, this support is independent from the current control
for each stepper, which is still done individually.

The enable lines are not one per stepper - instead there are 5
distinct enable settings. Handle them properly.
