The ATmega128RFA1 and ATmega256RFR2 contain a version of this IP
on the MCU.
The radio core behaves mostly like a at86rf231, but all registers
are mapped to memory and radio states can directly generate interrupts
on the CPU.
The ATmega256RFR2 adds support for automatic retransmissions.
This has not been implemented yet.

Fix the condition to return -ENOPNOTSUPP when i2c repeated read attempted.
Currently the error occures even if a read after write is attempted.
This is the standard way to i2c_read_reg which should be supported.
The -EOPNOTSUPP requires the previous R/W state to be reading.
This means a `I2C_SR2_TRA` must be checked to be 0.
There is no hardware limitation for custom boards based on STM32 to uses
SPI bus with signals coming from different PORT and alternate functions.
This patch allow alternate's function definition per pin basis, thus enable
the support of SPI bus signals routed on differents PORT.

Added a script to determine the sizes of the default C11 atomic types and
generate an C++ header with preprocessor defines to access the sizes of the
types and an integer type of the same size (and therefore alignment
requirements).
Added a header to allow defining C interfaces using the default C11 atomic
types. Those types are however fully opaque and inaccessible from C++, as C11
atomics are completely incompatible with C++.
changed wan -> WAN, codespell help says:
"Words are case sensitive based on how they are written in the dictionary file"
Thus WAN doesn't match but "wan" does.
Also added "dout" (short form of digital out).
`_match_to_idx()` was removed from source address selection (which was
the only one setting the filter parameter to a non-NULL value), so it
is the parameter is not needed anymore.
When source address selection is done, both RFC and comments in the code
state, that a longest prefix match should *only* be used as a
tie-breaker between more than one viable candidate. If there is only one
address, there is
a) no need for a tie-breaker
b) in the case of either the destination address or the single remaining
address being ULAs ([which are considered to be of global scope]
[RFC4193]) possibly not matching, as `fd00::/7` and e.g. `2001::/8`
do not have a common prefix.
(b) in fact causes the match function to return -1, causing the source
address selection to return -1, causing the outer function to return the
first address it found (which most often is the link-local address),
causing e.g. a ping to an ULA to fail, even is there is a global
address.

- Move serial.inc.mk in remote and openmote-b Makefile.include before
PROG_DEV to avoid repeating OS logic check
- Add deprecation warning for PORT_BSL
- Move serial.inc.mk in mega-xplained/Makefile.include after
PROG_DEV so PROG_DEV can still default to PORT
- Add deprecation warning for arduino-leonardo and mega-xplained
Different platforms evaluate `printf()` for NULL pointers differently,
resulting tests checking for a certain output to fail. This unifies that
(debug) output for the static packet buffer statistics.
