Updated GoMacH again and tackled a series of bugs and issues, which introduced memory leak and timing chaos in transmissions (some were introduced when rebasing).

After that, evaluated GoMacH through a second long-time stability experiment:
A multi-hop test-bed of SAMR21-xpro with at most 3 hops transmission. All the nodes were deployed in my office room environment (all nodes are in each other's radio/interference range). All nodes (except sink) generate data packet and send/relay the packets to the sink.

Application: based on the default application in RIOT/examples/default
Cycle duration of all nodes: 200ms;
data rate: 1 packet / 1 seconds per node.
Maximum link layer packet retransmission: 6 times.
**Experiment duration: 48 hours (two days)**.

**Results:**
```

2017-09-14 12:36:31,981 - INFO # 8032, 180066, 180066, 898816.
```
Packet deliver ratio: 898816/898830 = 99.9984424195899%. Only 14 packets dropped.

Going to run a third long-time stability evaluation experiment.
