  1. Fix core panics: Don't use m_malloc and gc_malloc unintended 

    MicroPython's "gc_alloc" and "m_malloc" functions should
probably not be invoked from within C-level RTOS extensions.
Otherwise, the garbage collector might want to prune memory
which does not really hold MicroPython objects.
This eventually leads to random core panics.

  2. Fix integer overflow in filesystem stat implementation. 

    Using small ints for storing st_atime, st_mtime and st_ctime values
is prone to integer overflows, effectively yielding wrong timestamps.

This resolves #409. Contributed by @robert-hh.

  3. extmod/modonewire.c: Add "modonewire" from Genuine MicroPython 

    This tremendously improves robustness of 1-Wire support.
While the original Pycom implementation is written in pure-Python,
this adds the C-level "modonewire" module from Genuine MicroPython.

It will also perform crc checks when reading the DS18B20 sensors.

  6. mods/machuart.c: Support the UART inverted mode 

    Inverted mode can be set by a keyword argument to init or the
constructor, using invert=<option|option...>
options are: INV_RX, INV_TX, INV_RTS and INV_CTS

Example:
from machine import UART
uart=UART(1, 9600, invert=UART.INV_TX|UART.INV_TX)

  7. Diverse changes to uos.stat() and UART modules 

    - Use long int for time stamps in uos.stat() because of short int overflow
- Simplify display of the UART config
