Mixed channel random test between Java and C

[frankbenoit]

The test shall run for a given time, e.g. 1 min, 10 min, ..
There shall be 10 channels, in 4 priorities:
Prio 0 (high): ch 0, ch 4 (5%)
Prio 1: ch 1, 2, 6, 7 (15%)
Prio 2: ch 3, 9 (25%)
Prio 3 (lowest): ch 5, 8 (rest %)

The test shall first measure the single channel bandwith.

Then the test limits the bandwidths per channel:
ch 0, prio 0, < 1%, packet size <100
ch 1, prio 1, < 5%
ch 2, prio 1, < 5%
ch 3, prio 2, < 10%
ch 4, prio 0, < 4%
ch 5, prio 3, < 10%
ch 6, prio 1, < 2%
ch 7, prio 1, < 3%
ch 8, prio 3, no limit, fill up the bandwidht to 100%
ch 9, prio 2, < 15%

The test comes in 2 variant: PUSH and PULL
PUSH: the receiver side is fully open, and the sender pushes the data accordingly to the bandwidth limits.
PULL: the sender has infinite data available, and the receivers control via ARM packets accordingly to the bandwidth limits.
