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.

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 extruder check_move() code will permit moves with huge extrusion
ratios if the amount extruded is tiny. (Some slicers emit these silly
moves - they are allowed because they are harmless.) Unfortunately,
the pressure advance code did not handle the huge extrusion ratios -
it would result in a massive, near instantaneous, extruder move in an
attempt to build pressure in the extruder. Catch this case and limit
the impact to the pressure advance code.

Added the pwm_cycle_time option for heater config sections. Defaults
to previous value of 0.100 seconds, but may be reduced to shorter times
at the expense of MCU workload and possible MOSFET heating, depending on
controller design. Some printers that need bed PID to be enabled,
notably the Felixprinters series, are known to benefit from shorter
cycle times, as the default 10hz rate results in excessive voltage
supply droop.
While this option can be used on extruder heaters as well, there
is not expected to be any particular benefit from doing so unless
the extruder heater presents a particularly large load.

Commit 002dc0df added rounding to the homing speed, but it did not
work if the configured homing speed was less than the printer's
maximum velocity. Move the speed rounding from stepper.py to
homing.py and make sure the rounded speed is less than the maximum
speed.
