STM32:  Allow clock frequencies > 168 Mhz on stm32f427/429.  We need to enable the power overdrive for this case.  This patch allows the required bits to be set in proper sequence.  It also modifies the local register access operations to allow more than 16-bit registers.

/configs/clicker2-stm32/mrf24j40-6lowpan: Enables both client and server UDP tests on the target; Update a README file.

Use struct instead of pointer to the struct as sizeof argument in memset in usbmsc.c

Approved-by: Gregory Nutt <gnutt@nuttx.org>

Otherwise it leads to error: argument to 'sizeof' in 'memset' call is the same pointer type 'struct usbmsc_lun_s *' as the destination

Update TODO, enable UDP example in clicker1-stm32/mrf24j40-6lowpan example, make sure that CONFIG_EXAMPLES_UDP_NETINIT is set in all other examples/udp configurations.

stm32_adc: invalidate dma buffer before use.  Missing invalidation caused old samples being fetched from cache.

IEEE 802.15.4 Network Driver:  Add logic to setup the network mask, update the MAC-based IPv6 addressing when the network is brought up.  The idea is that addressing changes are supposed to occur only while the network is down but won't take effect until the network is up again.

ieee 802.15.4:  Need counting protection on the logic that releases the notification resources.  Otherwise, notification handlers may be operating with a stale pointer.

IEEE 802.15.4 MAC: Add list management and prioritization logic that will permit the MAC layer to support bound multiple clients.

rfc6775: Fix header, add references, correct naming.  This is NOT ICMPv6, but part of 6LoWPAN that acts like ICMPv6.
