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.

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.
