In practice, these errors are usually due to problems on the host
computer instead of problems with communication.

HTU21D sensor class lacked the method `get_report_time_delta` invoked
during watermark control loops. This short fix simply adds that method
in, calling the `self.report_time` attribute created during class
construction.

This adds support for BMP280 and BME680 sensor ICs,
along with fixing calibration data readout for BME280.
Gas sensor readout for the BME680 is just the raw compensated value.
To get actual meaningful values, more research is needed.

The tmc2660 spec has an ambiguous "SG" field that sometimes refers to
the "stallGuard" flag and sometimes refers to the "SG_RESULT" field.
The tmc2130 and tmc5160 have similar fields that are not ambiguous, so
adopt that naming strategy.

Add functionality to support a Filament Motion Sensor for detecting extruder jams as well as runouts. Works by an encoder toggling the switch_pin 0/1 as the filament is pulled through the sensor.

The tmcuart_send command increases cpu usage on the micro-controller.
Should multiple tmcuart_send commands be issued at the same time to a
single AVR micro-controller, it could increase the load to the point
that it introduces a failure. It could also lead to tmcuart_send
transmission errors, which would cause retransmission requests, which
further increase the load.
Track and share mutexes so that only one tmcuart_send command can be
active on a single mcu at a time.

None of the other TMC driver enable SFILT by default and it seems

Machines that have no heaters produce an error when the idle timeout occurs. This commit fixes this by checking if there are any heaters to turn off.

Introduce a heaters.set_temperature() command and call that from
commands that set a heater temperature. This new function calls
toolhead.register_lookahead_callback() so that the idle_timeout gets
notification that activity has occurred.

This adds new config options for fans: 'tachometer_pin' to specify the
GPIO pin, and 'tachometer_ppr' (default 2) to specify the number of
signal pulses per revolution. The rpm is also exposed by get_status for
command templates and the API server. For fast fans (at least 10000
RPM), the polling interval can be shortened using the
'tachometer_poll_interval' option.
There is a new mcu object for a generic edge counter, which repeatedly
polls a GPIO pin and periodically reports the count to the host.

If `klippy` loses connection to a device, the next `read()` from the
device file descriptor will result in a zero-byte result, i.e. an `EOF`.
Right now this gives a confusing error message, so this simply handles
the special case of `EOF` and outputs a better log message.
Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>
When `serialhdl` opens a terminal device it must prevent the device from
becoming the controlling terminal of `klippy`, as such a terminal will
send additional messages to the session leader, e.g. a SIGHUP, which
would kill `klippy`. See e.g. #3981.
pySerial already does this, but for e.g. `klipper_mcu` we were not doing
this ourselves.
On Linux a process must set `O_NOCTTY` when opening any file that could
potentially be a terminal device, to avoid this.
Earlier process daemonization tools prevent this from being an issue by
double forking, but under `systemd` a process must take steps to avoid
opening a controlling terminal.

With commit 53b10d3a the setup of sensorless homing could occur before
the driver was enabled which would cause the reinitialization of the
driver settings to undo the sensorless homing setup.
Use set_field() when setting the sensorless homing registers so that
it wont conflict with a driver init.

Send the full TMC stepper motor driver initialization sequence every
time the driver is enabled.
Don't raise an error on startup if unable to contact a tmc2208/tmc2209
driver. If the driver is still unavailable when it is enabled then a
shutdown will be issued. This allows users to troubleshoot (and
possibly bring up communication to the driver) prior to enabling the
driver.

The tmc2660 appears to send responses as soon as the clk starts
toggling. That means the 20 bit response is at the top of the 24bit
sent message. Also, this implies that RDSEL must already have the
correct value in the prior message.

Where the tmc2660 flags match other drivers, use lowercase so that the
same monitoring code can be used for all the tmc drivers. Also, use
the same field formatters where applicable.

The tmc5160 field formatters were mostly duplicates of the tmc2130 -
add the "reset" field to tmc2130.py so both drivers have similar
