examples/touchscreen:  Add a configuration option to indicate that there is or is not an architecture-specific initialization function

apps/netutils/ntpclient:  Add a primitive NTP client.  Initial checkin is untested and probably incomplete

Back out part of  610e2aa0c224e2936fe8009ef4a2351ce607067a: Need to be able to select USB console devices when there is no /dev/console enabled.  Noted by Librae

apps/system/usbmsc:  Back out kludge that is no longer needed with the recent fix to the USB MSC class

apps/examples/igmp:  Fill out empty Kconfig file; can now be built as an NSH builtin function.  From Manuel Sthn

dhcpd_allocipaddr() should not call ntohl().  The return value is already in host order.  From Brennan Ashton

NSH cat command now adds to newline at the end of the file so that the NSH prompt is always on a newline

NSH telnet: Use strncpy vs strcpy to avoid overrunning username and password buffers.  From Bertold Van den Bergh

Add CONFIG_DEFAULT_SMALL that will select default values for configuration settings based upon either more features or smaller footprint.  Turns out not be be useful for modifying existing defconfig files because the defaults do not apply in that case

unlink/rm can now be used on nodes in the pseudo-filesystem.  There is new configuration option to suppress these costly and mostly useless operations on the pseudo-filesystem

More changes to reduce complaints from CppCheck.  Some latent bugs fixes, but probably some new typos introduced

Add a mouse interface that is similar to the touchscreen interface except that it can handle multple buttons and continuously reports positional data so that it can control a cursor

VI: all commands not seem functional.  Still at least on display artifact and probably some things not properly tested

NSH:  Add a break command; if-then-else and looping behavior can not be configured out of the build for small systems that need minimal scripting capability

NSH:  Loosen up if-then-else-fi syntx so that a command can be on the same line as the 'then' and 'else' tokens.  This allows, as an example, 'if true; then echo true; else echo false; fi' which is much more bash-like
