SLIP-radio support for the Nooliberry (RF230 radio)
SLIP-radio support for the Econotag
Restore CC2420 as default in slip-radio
In stm32w_flasher replaced hal-* calls with usage of pyudev.
Added support for STM32w boards MB950 and MB951 revision B.
In stm32w_flasher added check for pyudev and updated ubuntu package instructions.
Bugfix: if a SYN is received in the SYN_RCVD state we should not send a blank SYN, but a SYNACK in response.
Bugfix: correctly handle the case if uip_sappdata is NULL.
Allow the default TTL to be configured with UIP_CONF_TTL
Produce an error if the UIP_TCP_MSS is too large for UIP_BUFSIZE
Enable the silent compilation mode from the latest Contiki
An implementation of the mc1322x watchdog
Rewrote the IPv6 route management so that all routes are maintained on a list that is ordered by the time at which the route was accessed. If a new route is added to the system, the oldest route is dropped.
cc2538: Clean up port and pin definitions

Homogenize port and pin definitions naming:
 - PERIPHERAL_FUNCTION_PORT for the port ID,
 - PERIPHERAL_FUNCTION_PIN for the pin ID,
 - PERIPHERAL_FUNCTION_PORT_BASE for the port base,
 - PERIPHERAL_FUNCTION_PIN_MASK for the pin mask.

Define only PERIPHERAL_FUNCTION_PORT and PERIPHERAL_FUNCTION_PIN in board.h, and
deduce PERIPHERAL_FUNCTION_PORT_BASE and PERIPHERAL_FUNCTION_PIN_MASK in the
driver from the former definitions.

cc2538: usb: Make the GPIO driving the pull-up optional

The data sheet recommends that the USB pull-up resistor be driven by a GPIO so
that it can be controlled by software, but this is not mandatory. Hence, leave
the choice so that CC253-based boards not using this option can build and work
fine.

cc2538: lpm: Give access to the SRAM non-retention area for PM2

If PM2 is enabled with LPM_CONF_MAX_PM, but not active, the non-retention area
of the SRAM can be useful to place temporary data that does not fit in the
low-leakage SRAM, typically after having called lpm_set_max_pm(LPM_PM1). Hence,
give access to this non-retention area thanks to .nrdata* sections.

cc2538dk: Make it possible to override SLIP_ARCH_CONF_ENABLED

As the comment in contiki-conf.h says, the automatic definition of
SLIP_ARCH_CONF_ENABLED works only if UIP_FALLBACK_INTERFACE is tied to SLIP. If
UIP_FALLBACK_INTERFACE is set to another interface, SLIP_ARCH_CONF_ENABLED is
still automatically set to 1, leading to unwanted SLIP_END characters from
dbg.c:putchar() being printed on the UART.

This change makes it possible to force the definition of SLIP_ARCH_CONF_ENABLED
(e.g. from project-conf.h), so that it can be disabled if UIP_FALLBACK_INTERFACE
is used with something else than SLIP.

cc2538: gpio: Add macros to use GPIO power-up interrupts

The GPIO power-up interrupts have to be configured and enabled in order to be
able to wake-up the SoC from PM1+ upon a signal edge occurring on a GPIO input
pin.

This set of macros allows to:
 - configure the signal edge triggering a power-up interrupt,
 - enable and disable a power-up interrupt,
 - clear a power-up interrupt flag.

cc2538: gpio: Clear the power-up interrupts in the port ISRs

The pending GPIO power-up interrupts have to be cleared in the ISRs in order not
to re-trigger the interrupts and the wake-up events.

The power-up interrupts of all pins are cleared for each port in the
corresponding port ISR. This is done after calling the registered callbacks so
that the callbacks can know which pin woke up the SoC. This is done after
clearing the regular interrupt in order to avoid getting a new wake-up interrupt
without the regular interrupt in the case of a new wake-up edge occurring
between the two clears.
