    loadable app support

    * apps: Introduce a build system for loadable apps for nsh.

        This PR consits of following changes. (NOTE: Changes to each
        application will be provided separately)

        apps/nshlib/Kconfig:
        Add 'option modules' to NSH_FILE_APPS so that a user can change
        an application configuration to tristate (y/n/m)

        apps/Make.defs:
        Override COMPILE and COMPILEXX macros to compile loadable apps.
        To make loadable apps, -DLOADABLE_APP is added to the flags.
        Also, introduce ELFLD to link a lodable app.
        Please note that the variable 'LOADABLE' must be defined in
        each application Makefile if you want to make a loadable app.

        apps/Application.mk:
        Add .build target in case of 'LOADABLE=y' which is used to
        link a final loadable application and install the app to
        apps/bin.

        apps/Makefile:
        Add SYMTABSRC and SYMTABOBJ variables for loadable apps which
        will be generated under the apps directory.
        Add make_symbols target which will be called when all applications
        are installed to generate symtab_app.c which is used for
        nsh to inform symbol information to the NuttX kernel.

    * apps/examples/hello: Apply changes to support a lodable app.

        Kconfig:
        Change the application state from bool to tristate

        Make.defs:
        Change the condition to build. By default, the application is
        not selected (i.e. 'n'), so if other states (i.e. y/m) are
        selected, the application will be compiled.

        Makefile:
        If the application is specified to 'm', the variable 'LOADABLE'
        must be defined here. Also note that other variables (PRIORITY
        and STACKSIZE) can only be used for built-in apps.

        hello_main.c
        Add LOADABLE_APP condition to main().

config EXAMPLES_HELLOXX

Enable the \"Hello, World!\" C++ example

config EXAMPLES_HELLOXX_CXXINITIALIZE
bool "C++ Initialization"
default y
depends on HAVE_CXX && HAVE_CXXINITIALIZE
---help---
By default, if CONFIG_HAVE_CXX and CONFIG_HAVE_CXXINITIALIZE are
defined, then this example will call the NuttX function to
initialize static C++ constructors. This option may be disabled,
however, if that static initialization was performed elsewhere.
