b6d94d9525 nrf24l01p: Remove superfluous delays in nrf24l01p_on, nrf24l01p_off. 
The delays were introduced in an attempt to fix "inexplicable timing
errors", although the errors were in the SPI bus driver rather than the
nrf24l01p driver.

a991d7c58e nrf24l01p: Remove redundant gpio_clear/gpio_set. 
This change removes extra gpio_clear(dev->cs) before calling
nrf24l01p_read_reg(), nrf24l01p_write_reg(). The GPIO handling is not
necessary since nrf24l01p_{read,write}_reg() handle the CS pin
internally.

7095241555 rpl: wrong macro definitions in rpl shell commands 
It appears that the values defined for RPL_NODE_IS_ROOT and
RPL_MAX_ROUTING_ENTRIES in the Makefile via CFLAGS are not recognized in
sc_rpl.c (my guess: they are only visible to the rpl module?)
Therefore RPL_MAX_ROUTING_ENTRIES is always set to 0, no matter how the
binary is compiled, thus resulting in the output "No routing table
available" for root nodes.

c4b01b87bc rpl: RPL/Trickle with only *one* thread 
This PR proposes an approach to reduce the thread count of RPL.

The current RPL/Trickle stack needs about 5 threads to handle tasks
like updating the trickle timer, routing entries and the transmission of
DAOs.

This PR modifies RPL to use only one thread with a looped `msg_recv()` call.
The message is then multiplexed to the right task.

88fa49ab38 cpu/native: add high-quality random implementation 
Per default random data is read from `/dev/random` now.

If specified (e.g. `-s 4711`), data is generated by calls to POSIX
random function like before. The POSIX random API is initialize with
the given seed (`srandom(4711);` in this example).
