Add DISABLE_TRANSPORTS switch which disables build of all transports and examples using them.
Disable compilation of USB and UART transports if NCP_SPI switch is set. This also disables
the build of CLI example.
This commit changes the behavior of `Mle` to skip the saving of
network info (to non-volatile memory) on role change to detached. Note
that `Store()` does only update the MAC/MLE counters if device is not
attached. The MAC/MLE counters update is tracked already by
`KeyManager`.
This commit adds new check in `settings.cpp` for saving of
`NetworkInfo` and `ParentInfo` in non-volatile memory to verify that
the new value is different from previously saved content. This reduces
number of writes after a device reboot.
This commit adds code to ensure `SETTINGS_CONFIG_PAGE_NUM` is at
least two. This helps simplify the code and also address
Coverity warnings for unreachable code.
Currently SETTINGS_CONFIG_PAGE_NAME is defined indirectly by addresses of
__d_nv_mem_start and __d_nv_mem_end. But such definition doesn't allow to
perform compile time sanity check. Define this macro with const value 16.

OT doesn't always call otPlatRadioReceive to set rx state explicitly. It
causes RF is in wrong state in some cases. SAMR21 RF is switched to
rx state internally when tx is finished and OT platform radio state should
be updated accordingly. This fix is set sState to OT_RADIO_STATE_RECEIVE
when tx is done.

samr21 has HW aes-128 module. It couldn't be used before as mbedtls uses
256 bit random generator. Recently mbedtls introduces
MBEDTLS_CTR_DRBG_USE_128_BIT_KEY flag which makes mbedtls to use 128 bit
random generator. It limits the security of generated keys but allows
to use HW aes-128 module for encrypt/decrypt 802.15.4 frames.

By default Makefile-samr21 builds for SAM R21 Xplained Pro board. Another
board can be specified with BOARD variable through command line:
make -f examples/Makefile-samr21 BOARD=<TARGET_BOARD>
Currently supported following boards: SAMR21_XPLAINED_PRO,
SAMR21G18_MODULE, SAMR21B18_MODULE.

samr21 rf driver requires that first byte of transmit buffer should be
psdu length. The psdu was copied to a local buffer with one byte shift then
the local buffer was passed to rf driver. This copying is removed by
extending length of sTransmitPsdu by 1 byte and use &sTransmitPsdu[1] as
transmit frame psdu.

Internal compiler.h defines __always_inline macro and includes cdefs.h
indirectly. cdefs.h also defines this macro. As result we have redefined
macro error which can't be suppressed. The fix is to use custom compiler.h
which is copy of ASF compiler.h bu defines __always_inline only if it is
not yet defined.

The attach state `kAttachStateSynchronize` was intended for sending
"Child Update Requests" after a reset (if device was previously
attached) using the `mAttachTimer` for retransmissions. However,
"Child Update" transmissions use `mMessageTransmissionTimer`
instead.
This commit changes `SetStateChild()` to stop `mAttachTimer`. This
ensures that as the `mAttachState` is set to idle, the attach timer is
also stopped (note that the attach timer callback asserts on idle
attach state). This addresses a rare issue where an inopportune device
mode change request on an already attached device while it is
performing periodic parent search (or possibly delaying processing of
a received announce) could cause an assert; `SetDeviceMode()` would
call `SetStateChild()` setting the attach state to idle while attach
timer would continue to run.
This commit enables a node serve as the border agent of native commissioner
by adding the border agent UDP port to unsecure port when the security
policy allows.
To fully test verify this commit, we need a native commissioner, which I
will submit a separate commit to enable that.
