Initial cut of a driver for the TI CC3000 network module with support on the Freescale KL25Z board from Alan Carvalho de Assis

Add example configurations that enable USB trace options must have Kconfig options to select the trace output

Clean up some LP17xx and STM32 USB host configuration compilation errors due to the massive changes to the USB host interfaces needed to support the SAMA5

A few more zmodem files; still missing a few but those are still fragile and like to undergo some resign before they are usable

Fix UG-2832HSWEG04 landscape.  Add reverse landscape support to UG_2864AMBAG01 and UG-9964HSWAG01.  Fixe NXHELLO default colors for 1-bit mono modes

Add support for the UG-2843HHSWEG04 OLED and for the SAM4L Xplained Pro OLED module that uses that OLED.

Straighten out issues about who calls C++ initializers with CXXTEST or HELLOXX are built as NSH applications; Add an ofstream test to CXXTEST suggested by Michael; Update many defconfig fiels to that they set configurations to handle C++ constructors just as before these configuration changes

Remove CONFIG_XYZ_BUILTIN configurations, replace with the single CONFIG_NSH_BUILTIN_APPS.  Add SAM3/4 sam_periphclks.h which is just a header file that includes the right header file.  Misc SAM3U-EK cleanup

Add missing NSH configuration settings.  Correct some conditional logic for STM32 FALSH pre-fetch settings.  From Lorenz Meier

Move SAM3U header files to arch/arm/src/sam3u/chip. Some renaming of SAM3U to SAM to ssupport SAM4.  Convert all configs/sam3u-ek configurations to use the kconfig-frontends tool
