[PATCH 0/4] kconfig: tests: Minor fixes and cleanups for warn_changed_input

[Nicolas Schier]

This patch-set contains two minor fixes and some related cleanup for the
warn_changed_input test:

  * The kconfig test 'warn_changed_input' fails if the environment
    variable KCONFIG_WARN_CHANGED_INPUT is set non-empty.  The first
    patch resets KCONFIG_WARN_CHANGED_INPUT by default for all tests
    to make the 'warn_changed_input' test more stable.

  * The kconfig test framework provides 'olddefconfig' and
    'savedefconfig' wrappers, which fail short when it comes to real
    usage.  The 'warn_changed_input' worked-around by calling the
    framework-internal '_run_conf' function.  The remaining three
    patches extend 'olddefconfig' and 'savedefconfig' wrappers and
    simplify 'warn_changed_input' appropriately.
