I just made corresponding changes to unix: acb1388 , and I suggest stmhal and other ports to follow - it's important to let people reliably test/recover from errors.

I also going to add "errno" module to micropython-lib, and then I suggest for stmhal to use the same numeric codes as Linux ;-).

Okay. Leave this open until I (or someone) gets round to it. I guess that's what issue trackers are for, after all!

stmhal, file: Implement a,x,+ open modes, seek and tell.

Also now returns correct POSIX errno when an IO operation fails.

Addresses issues #516 and #676.

stmhal/file.c now uses POSIX error codes, and returns a numeric errno as the first argument, following unix/file.c.

Prevent freezing USB during high frequency PulseIn.

We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

Fixes micropython#516 and micropython#876
