arch/arm: Remove support for CONFIG_ARMV7M_CMNVECTOR. It is now the only vector support available. Also remove CONFIG_HAVE_CMNVECTOR. That no longer signifies anything."
arch/arm/src/stm32: This commit removes support for the dedicated vector handling from the STM32 architecture support. Only common vectors are now supported.
drivers/wireless: Adds XBee S2C (802.15.4 firmware) support. XBee driver emulates mac802154 interface
* drivers/wireless/xbee: Adds xbee_netdev. Very similar to mac802154_netdev
* configs/same70-xplained: Starts adding support for XBee radio
* drivers/wireless/ieee802154/xbee: More structuring of XBee driver
* drivers/wireless/ieee802154/xbee: More Xbee work. Starts adding support on Clicker2
* drivers/wireless/ieee802154/xbee: More XBee MAC code
* configs/clicker2-stm32: More work to add XBee radio support
* drivers/wireless/ieee802154/xbee: Most of driver is now structured. No build errors
* configs/clicker2-stm32: Adjustments to XBee click module support
* drivers/xbee: Changes md_ prefix to xd_ prefix for xbeenet_driver_s fields
* drivers/xbee: XBee network device now passes MAC events via IOCTL
* drivers/xbee: Support querying device for parameters, setting parameters, and structures association/startpan logic
* configs/clicker2-stm32: Fixes Xbee lower half ATTN poll logic
* drivers/xbee: Removes dependce on CONFIG_IEEE802154_NETDEV
* drivers/xbee: Supports MAC RESET.request primitive
* drivers/xbee: Exposes generic AT query to the rest of driver
* drivers/xbee: Sets local values when writing setting change to Xbee device
* drivers/xbee: Finish association logic
* drivers/xbee: Adds xbee_get_mhrlen( ) allocating enough space for API frame header to frame
* drivers/xbee: Finishes transmit/receive logic
* drivers/xbee: Fixes xbee_netdev to match logic in mac802154_netdev.c
* drivers/xbee: Rearranges logic to prevent a loop condition where recursion could potentially occur to the point of deadlocking the system
