Extend slip-radio example for Econotag and Nooliberry

In stm32w_flasher replaced hal-* calls with usage of pyudev.

i2c and eeprom drivers for mbxxx boards

Fix sleep

Add a rule for generating assembly listings on mc1322x targets, for example: "make webserver6.lst".

Added support for STM32w boards MB950 and MB951 revision B.

This reverts commit eac73ff68ce98e862def4bd671db03f7b9a3b438.

MC1322x additions

IPv6 routes LRU

Remove the VNC client and server

Removing the experimental checkpoint functionality

Enabled shell_rime_send_cmd_init() so that this example can be used in the shell/03-sky-shell-command regression test

Allow user configuration of RadioLogger pcap file

This patch improves the eeprom-test example adding more
tests on the eeprom read/write procedures.

This patch adds the eeprom driver needed to access M24C64
eeprom which is on some mbxxx boards.

mac: Fix false duplicate packets detections

According to IEEE 802.15.4e (§6.4.3.9), in order to detect duplicate received
MAC-layer frames, only the most recently received frame's sequence number needs
to be stored for each unique device address. Doing so limits the possible false
duplicate packet detections to a single sequence number. This also allows to
keep the last sequence number of more device addresses for the same value of
MAX_SEQNOS.

The code detecting duplicate packets in the RDC layer had been copied into most
RDC implementations. Factor it out into a new mac-sequence module in order to
have a single instance of this code.

According to IEEE 802.15.4 (§5.1.6.1, §6.4.2), the MAC sequence numbers should
be initialized to random values. This was already the case in
framer-802154.c:create(), but not in csma.c:send_packet(), sometimes causing
false detections of duplicate MAC-layer packets in other devices when a device
was restarted too quickly. This patch decreases the probability of such an
event.
