9fbab8f0f8 drivers/slipdev: report NETOPT_ADDRESS to simulate l2 address 
A lot of things break if `GNRC_NETIF_FLAGS_HAS_L2ADDR` is not set.
In order to handle router advertisements and auto-configureation,
generate a faux l2 address based on the netdev ID.

This commit removes the dependency to xtimer and RIOT messages.

sys/net/gnrc/tx_sync: new module 
The new `gnrc_tx_sync` module allows users of the GNRC network stack to
synchronize with the actual transmission of outgoing packets. This is directly
integrated into gnrc_sock. Hence, if `gnrc_tx_sync` is used, calls to e.g.
sock_udp_send() will block until the network stack has processed the message.

Use cases:
1. Prevent packet drop when sending at high rate
    - If the application is sending faster than the stack can handle, the
      message queues will overflow and outgoing packets are lost
2. Passing auxiliary data about the transmission back the stack
    - When e.g. the number of required retransmissions, the transmission time
      stamp, etc. should be made available to a user of an UDP sock, a
      synchronization mechanism is needed
3. Simpler error reporting without footguns
    - The current approach of using `core/msg` for passing up error messages is
      difficult to use if other message come in. Currently, gnrc_sock is
      busy-waiting and fetching messages from the message queue until the number
      of expected status reports is received. It will enqueue all
      non-status-report messages again at the end of the queue. This has
      multiple issues:
        - Busy waiting is especially in lower power scenarios with time slotted
          MAC protocols harmful, as the CPU will remain active and consume
          power even though the it could sleep until the TX slot is reached
        - The status reports from the network stack are send to the user thread
          blocking. If the message queue of the user thread is full, the network
          stack would block until the user stack can fetch the messages. If
          another higher priority thread would start sending a message, it
          would busy wait for its status reports to completely come in. Hence,
          the first thread doesn't get CPU time to fetch messages and unblock
          the network stack. As a result, the system would lock up completely.
    - Just adding the error/status code to the gnrc_tx_sync_t would preallocate
      and reserve memory for the error reporting. That way gnrc_sock does not
      need to search through the message queue for status reports and the
      network stack does not need to block for the user thread fetching it.

f7a77ebb04 drivers/nrf24l01p_ng: netdev driver for nrf24l01+ 
The driver uses the netdev interface. Due to the limited
capabilities of the transceiver (32 byte FIFO and no source address in the layer2 frame),
it relies on 6LowPAN compression and adds the source address to the frame for that.

sys/net/gnrc: fix in-band signaling of no RSSI 
Previously a value of 0 was used for the RSSI to signal that this value is not
present in `gnrc_netif_hdr_t`. However, an RSSI of 0 dBm is legal and even very
plausible data.

This commit defines `GNRC_NETIF_HDR_NO_RSSI` as `INT16_MIN`, which is below the
noise floor in the vacuum of outer space and hence impossible to receive.
For consistency, also GNRC_NETIF_HDR_NO_LQI is defined.

gnrc_pkt: introduce packet list operations 
Up until now `utlist.h` is used to manipulate the packet list within a
GNRC pkt snip. Since I always wanted to see if there would be an
advantage when using `core`'s `list.h`, I provide this
`gnrc_pktsnip_t`-specific API to manipulate the packet list. It has the
additional advantage of type safety and that future steps could
encapsulate those operations.

sys: Cleanup access to internal variables 
Replace direct accesses to sched_active_thread and sched_active_pid with
the helper functions thread_getpid() and thread_get_active(). This serves
two purposes:

1. It makes accidental writes to those variable from outside core less likely.
2. Casting off the volatile qualifier is now well contained to those two
   functions
