Jim Mussared c2cfbcc8d4 unix: Implement MICROPY_BEGIN/END_ATOMIC_SECTION protection macros.
This macro is used to implement global serialisation, typically by
disabling IRQs.  On the unix port, if threading is enabled, use the
existing thread mutex (that protects the thread list structure) for this
purpose.  Other places in the code (eg the scheduler) assume this macro
will provide serialisation.
