These allow accessing the filesystem label. For instance,
in boot.py, you can set the label on the built-in storage with:
storage.remount('/', False)
storage.getmount('/').label = "NEWLABEL"
storage.remount('/', True)
Users with multiple CIRCUITPY boards may find it desirable to
choose a different label for each board they own.
If, for class X, X.__add__(Y) doesn't exist (or returns NotImplemented),
try Y.__radd__(X) instead.
This patch could be simpler, but requires undoing operand swap and
operation switch to get non-confusing error message in case __radd__
doesn't exist.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
