    apps/system/composite: Add a configuration option to the boardctl() calls to support multiple composite device configurations dynamically.

commit 7652b678
Author: Frank Benkert <Frank.Benkert@avat.de>
Date:   Thu Jun 1 15:19:40 2017 -0600

    Update to apps/system/compsite assocated with big changes to the composite device logic

apps/system/composite:  Fix configuration selecting.. was setting the port number, not the configure ID.  Also add a configuration option to select the default configuration.

system/composite:  Remove CDC/ACM and MSC configuration logic.  This belongs in the OS composite initialization.  Add and argument so that you can select the USB composite configuration to be attached.

Windows build fixes:  tools/mkkconfig.bat - switch APPSDIR path to use forward slashes for kconfig-frontends. interpreters/ficl - Reorder some targets that causes GNUwin32 make to behave badly.

tools/mkkconfig.bat:  Remove quotes in echo.  These were begin Echo'ed and generating double quots in the output.

apps/examples/keypadtest: REMOVED and warehoused in the Obsoleted repository.  This was just a bad clone of apps/examples/hidkbd for a keypad driver that was removed years ago.  It also uses illegal function calls into the OS.  So it has no purpse:  It is redundant, it uses illegal interfaces, and is a test for non-existent code.

NSH library: Fix build break in nsh_command.c with IPv4/IPv6 dual stack.
