STM32 F3:  Fix a couple of new warnings noted in build testing.  There are more new warnings, but I think these may be due to improper default values for some configuration settings.  I have not looked into this in detail.

arch/arm/src/stm32 and stm32l4:  In 1wire driver, do not write useless WRITEBIT zero return value to const buffer

fix w25_cacheflush sector bug.

stm32/Kconfig: add some comments to HRTIM configuration, add ADC injected channels configuration; stm32f33xxx_hrtim.h: add some comments; stm32f334-disco: add buck/boost converter example configuration

    drivers/1wire: add 1-wire subsystem and ds28e17 driver

This commit removes all support and all references to the Spark board and to the CC3000 wireless part.

Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>
    Fix a few remaining refereces to cc3000.

Author: Alan Carvalho de Assis <acassis@gmail.com>
    drivers/wireless/cc3000: emove the driver to support CC3000 because it doesn't use the USRSOCKET

Author: Alan Carvalho de Assis <acassis@gmail.com>
    configs:  Remove board support to CC3000 from all relevant configurations.

Author: Gregory Nutt <gnutt@nuttx.org>
    configs/spark:  Removes Spark board configuration.  Still available in the Obsoleted repository.  This is preparation for removal of CC3000 support by Alan Carvalho de Assis.  If there is no CC3000 support, then there is no purpose in supporting the Spark either.

wireless/bluetooth: With change the test with the simulated bluetooth driver can get all the way up the point where it determines that the attached controller is not LE capable.  I am not sure how much first to take the simulation.  The time would probably be better invested in bringing up real hardware.

wireless/bluetooth:  A few trivial fixes from initial testing with the simulator.  The simulated Bluetooth device is probably going to be in adequate for any level of testing.

drivers/wireless/bluetooth:  Add a NULL device to support some very low level testing on the Simulator.

include/nuttx/wireless and wireless/bluetooth:  Add support for an IOCTL command to enable Bluetooth security.

include/nuttx/wireless:  Remove const from some members of IOCTL structures.  The const makes it awkward to initialize the structure.

include/nuttx/wireless:  All Bluetooth IOCTL command data must begin with the interface name string.

wireless/bluetooth:  Completes basic Rx/Tx data paths.  Still missing:  device address discovery and pairing logic.

arch/arm/src/tiva: Fix compilation errors on Tiva ADC code when ADC is enable.  Please several cosmetic changes to files made during code review.

wireless/bluetooth:  Buffer allocation was always allocationg a new buffer, even if one was provided.. causing data loss.  Correct initialization of lengths:  IOB lenth includes data offset.  Bluetooth buffer length does not.

wireless/bluetooth and net/bluetooth:  Clean up some garbage left in Kconfig file that broke 'make menuconfig'.  Clean up some craziness with Bluetooth frame length definitions.

wireless/bluetooth:  Adds most of the logic to get the Tx path working.  Still missing the logic to recover the Bluetooth connection structure given the destination address in the socket address.

    wireless/bluetooth:  This completes the basic logic path that gets frames from the Bluetooth stack and into the network layer.
    wireless/bluetooth:  Fleshes out some of the network packet receive logic.
    wireless/bluetooth:  Replace buffer allocated with primitive allocator from ieee 802.15.4.
    wireless/ieee802154:  Fix a few typos.
    wireless/bluetooth:  More renaming in preparation for some real work.
    wireless/bluetooth:  Some trivial renaming; update comments

Bluetooth:  Bring in some definitions from NetBSD.  Update some usage and naming to be more consistent.

This comment adds (1) basic support for AF_BLUETOOTH sockets.  The logic compiles but is still incomplete.  Support for Bluetooth is general is still dependent on CONFIG_EXPERMIMENTAL because it is not yet ready for used.

Squashed commit of the following:

    wireless/bluetooth:  Some small changes that gets to a clean compile by just eliminating some incorrect implementations (still with a lot of warnings.  The logic is still incomplete but now not so lethal.
    wireless/bluetooth:  Restructuring:  Connection interfaces should internal to wireless/bluetooth.  include/nuttx/wireless/bt_conn.h removed and merged with wireless/bluetooth/bt_conn.h.  Several fix to get closer to bt_netdev.c compiling.  Need to design some not interfaces and use some existing interfaces to send and receiv packets.
    wireless/bluetooth: Some organization with some network device compile errors fixed.  Still not even close to compiling.
    net/bluetooth:  Fix numerous compile issues; Still open design issues with regard to the interface with the Bluetooth stack.
    wireless/bluetooth:  Create bt_netdev.c with a crude copy of mac802154_netdev.c.  Does not not even compile yet.
    include/nuttx/net:  Add bluetooth.h.  Content is not yet correct.
    net/netpackets:  Add bluetooth.h.  Update net/bluetooth to use new socket address definition.
    net/bluetooth:  Some fixes for initial build.
    net/bluetooth:  Add initial support for Bluetooth sockets.  The initial cut is just the a clone of the IEEE 802.15.4 socket support with name changes.
    net/ieee802154:  Fix some typos noted when cloning to create net/bluetooth.

net/udp:  Fix another related error in UDP condition compilatino (was actually using TCP setting, not UDP setting).
