For some reason, Linux creates the pseudo tty with group writable
permissions, but not group readable. Use chmod to allow the device to
also be group readable.

The gpio_out_toggle() function in the sam3x8e and stm32f1 code was
only valid if it was called with irqs disabled.
Commits 018c5daa and 9c52ad43 enabled the lcd code which called
gpio_out_toggle() with irqs enabled. This could cause corruption of
the gpio state.
Introduce a gpio_out_toggle_noirq() function that will only be invoked
with irqs disabled, and fix gpio_out_toggle() on sam3x8e and stm32f1
so that it safe to call even if irqs are enabled.

The step speed rounding and the cpu delay must be run after running
the endstop specific preparation code. Otherwise, a delay in the
home_prepare() code could undo those calculations. Specifically, this
could lead to errors on a multi-mcu setup when the Z is homed using a
virtual_z_offset and there is a delay in the activate_gcode section.

In order to properly delay BACKGROUND_PRIORITY_CLOCK messages, they
must be 5ms beyond the minimum defined by MIN_REQTIME_DELTA. So, add
both MIN_REQTIME_DELTA and MIN_BACKGROUND_DELTA to the timing of these
messages.

If the clock querying messages occur at a similar frequency to other
events on the micro-controller or host, then it's possible for the
load created by those other events to skew the clock synchronization.
In particular, the 500ms lcd screen update could resonate with the 1
second clock query. Use an unusual clock querying frequency to avoid
this issue.

Move the C code out of the main klippy/ directory and into its own

The AVR chips (bizarrely) start an ADC conversion when entering Idle
mode. This behavior can cause the ADC to be busy when a sample is
required. Worse, if a series of events cause the cpu to enter and
leave Idle mode with a timing similar to the ADC checking rate then it
can cause the ADC to show as busy for extended periods. This could
cause high MCU load and possibly lead to a "Rescheduled timer in the
past" shutdown.

The M206 command is confusing (it uses negative offsets) and isn't
very flexible. Add a new SET_GCODE_OFFSET command to make it easier
to add virtual offsets to gcode commands.

The M206 command is confusing as positive values in that command
result in negative offsets to future g-code commands. Perform the
parameter negation in the M206 command instead of storing it that way
internally.

When using an automatic probe, limit the Z lift speed to be no greater

If the fan's max power is limited by the config, then scale speed
requests between 0 and max_power. This makes more sense for typical
g-code fan speeds.

If max_accel_to_decel is greater than max_accel in the config, then
just internally limit max_accel_to_decel to max_accel. This makes it
easier to completely disable the max_accel_to_decel feature (as it can
just be set to a high value in the config).
