Subject: [PATCH] Split main Kconfig to allow application specific Kconfig

This will allow adding an application level Kconfig, for example

	mainmenu "Zephyr Application"

	config ZEPHYR_BASE
	    string
	    option env="ZEPHYR_BASE"

	config APPLICATION_BASE
	    string
	    option env="PROJECT_BASE"

	source "$ZEPHYR_BASE/Kconfig.zephyr"

	config TESTME
		bool "Test me"
		default y

	config BLAH
		bool "blah"
		default y

	source "$APPLICATION_BASE/src/Kconfig"

In the application file, add the following for example:

KBUILD_KCONFIG := $(PWD)/Kconfig
export KBUILD_KCONFIG
