The implementation is taken from stmhal/input.c, with code added to handle
ctrl-C. This built-in is controlled by MICROPY_PY_BUILTINS_INPUT and is
disabled by default. It uses readline() to capture input but this can be
overridden by defining the mp_hal_readline macro.
This method isn't implemented in any port. It seemed to have originated
in cc3200 port, but actually never was implemented there either. In
general case, it's impossible to implement this method (for example, for
a perfect GPO, which has only output latch without any feedback look
into a CPU).
For make v3.81, using "make -B" can set $? to empty and in this case the
auto-qstr generation needs to pass all args (ie $^) to cpp. The previous
fix for this (which was removed in 23a693ec2d)
used if statements in the shell command, which gave very long lines that
didn't work on certain systems (eg cygwin).
The fix in this patch is to use an $if(...) expression, which will evaluate
to $? (only newer prerequisites) if it's non empty, otherwise it will use
$^ (all prerequisites).
Previous to this patch the mp_emit_bc_adjust_stack_size function would
adjust the current stack size but would not increase the maximum stack size
if the current size went above it. This meant that certain Python code
(eg a try-finally block with no statements inside it) would not have enough
Python stack allocated to it.
This patch fixes the problem by always checking if the current stack size
goes above the maximum, and adjusting the latter if it does.
This patch fixes a regression introduced by

Previous to this patch the n_state variable was referring to that computed
at the very start of the mp_execute_bytecode function. This patch fixes it
so that n_state is recomputed when the code_state changes.
For consistent Pin/Signal class hierarchy. With it, Signal is a proper
(while still ducktyped) subclass of a Pin, and any (direct) usage of Pin
can be replace with Signal.
As stmhal's class is reused both as machine.Pin and legacy pyb.Pin,
high/low methods actually retained there.
