Rename adc_devinit() to board_adc_setup().  Add support to the boardctl() interface so that it can call board_adc_setup() on behalf of an application.  Change apps/examples/adc to that is now calls boardctl() instead of adc_devinit() in order to initalize the ADC device.

rch_tcinitialize() and arch_tcunitinitialize() renamed to board_tsc_setup() and board_tsc_teardown().  These are not long called directly by applications but only indirectly throught the crappy boardctl() OS interface.

NSH initialization now calls boardctl(BOARDIOC_INIT) instead of board_app_initaliaze.  Modify all configurations:  Make sure that CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears.  Remove support for CONFIG_NSH_ARCHMAC.  It is not used and there are better ways to do that operation

SAMV7 Ethernet:  I- and D-Cache are now enabled in the netnsh/ configuration.  D-Cache is enabled in write-though mode.  This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.

Make sure that FPU test, HID keyboard example, and touchscreen options are only available in the FLAT build

Fix two uses of DEBUG_COLORATION vs STACK_COLORATION (from David Sidrane).  Also some corrected comments

Fix some time value changes; mostly changing greater than 1000000000 to greater than or equal to 1000000000.  From Juha Niskanen

apps/examples/ostest: Sample errno on returns from sem_timedwait().  Otherwise, intervening system calls my change the value of the reported errno.  Noted by Juha Niskanen

apps/platform/Makefile:  Add a default defintion for DELIM.  Apparently it may not be present in certain causes during 'make distclean'.  From Michal Ulianko (SourceForge patch #47

NSH: The default priority of the network initialization thread should be lower.  It is CPU intensive and can interfere with other operations

apps/netutils/netlib:  Add utilities to convert to/from prefix lengths from/to 128-bit network masks.  Modify the NSH IPv6 ifconfig command to show the network mask in a more standard, human readable way.

ICMPv6:  Some initial bugfix from first tests of the ICMPv6 auto-configuration logic.  so far so good but a lot more testing is needed
