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.

apps/examples/thttpd:  Remove the netstats demo.  This depends on an illegal function call and cannot be supported.  That example could be replaced with logic that uses the procfs network entries as was done for NSH which had the same issue.  But I am too lazy to implement that
