This typically happens when there is a lot of data being received over the link. When the XBee stops responding, many times, querying the XBee kicks it out of this state. However, occasionally the XBee is completely locked up and the XBee has to be reset. This change handles these conditions by periodically (if not naturally occuring) querying the XBee. If during any query, the XBee does not respond within a certain number of attempts, the XBee is reset.
Xbee getset txpwr
* drivers/wireless/ieee802154/xbee: Minor improvements to debug facilities.
* drivers/wireless/ieee802154/xbee: Add support for setting/getting tx power.
TODO: The input/output arguments from the MLME primitive are intended to be an int32_t dbm value. However this change simply reports the power level register of the XBee. Need to add look-up table to back calculate the dbm value.

Xbee: Adds a timeout to send logic to handle case where XBee module fails to respond to a Transmit request with a Transmit Status
Approved-by: Gregory Nutt <gnutt@nuttx.org>
ieee802154: Simplifies notify() and rxframe() calls to a single notify() call. dataind's and all other "notifs" are now "primitives" which aligns with standard terminology
* mac802154: Adds missing breaks from case statement
* sixlowpan: Fixes bad logic where ACK is not requested if address is not a broadcast
* ieee802154: Simplification of "notifs" and "datainds" to generic primitives passed via a single notify call to the layer above the MAC
* Directories.mk should reference CONFIG_WIRELESS instead of CONFIG_DRIVERS_WIRELESS
* xbee_netdev: Network must be locked when calling sixlowpan_input
* sixlowpan: Reassembly buffer can't be freed if provided by radio driver
* sixlowpan: Don't free IOB if there is an error processing it as the MAC will try to pass it along to another receiver
* ieee802154: Adds basic logging to ieee802154_primitive.c
* Minor fixes after rebase
* xbee: Adds AT query timeout to retry if XBee doesn't respond to request
* same70-xplained: Adds Xbee support. Makes mikroBus slot Kconfig 'choice'
* mac802154: Removes unused function declaration
* drivers/mrf24j40: Fixes compilation error using . operator rather than -> operator
* mac802154_device: Changes a few mac802154_primtive_free's to ieee802154_primitive_free() and changes notif to primitive in a couple places.
* mac802154: Adds promiscous mode logic to bypass parsing of incoming frames. MAC char device also checks for promiscous mode and passes whole frames including header and FCS to the application if promiscous mode is enabled.
* sixlowpan: Fixes logic to correctly check if packet is large enough to include header. This would cause packets to be considered too small when they are sufficiently sized.
* sixlowpan: Fixes forwarding logic to use forwarding device rather than received device to look up destination link layer address
* net/ipforward: Fixes typo that caused build error when IP forwarding was enabled with CONFIG_NET_ICMPv6_NEIGHBOR enabled as well.
* configs/same70-xplained: Simple spelling fix

This commit backs out most of commit b4747286b1. That change was added because sem_wait() would sometimes cause cancellation points inappropriated. But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.
In the OS, all calls to sem_wait() changed to nxsem_wait(). nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.
In all OS functions (not libraries), change sem_wait() to nxsem_wait(). This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.
sched/semaphore: Add the function nxsem_wait(). This is a new internal OS interface. It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.
sched/semaphore: Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable. Changed all references to sem_post in the OS to nxsem_post().
sched/semaphore: Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable. Changed all references to sem_destroy() in the OS to nxsem_destroy().
libc/semaphore and sched/semaphore: Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable. Changed all references to sem_setprotocol in the OS to nxsem_setprotocol(). sem_getprotocol() was not used in the OS
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
