Subject: [PATCH] kconfig: make oldconfig less chatty and clean up conf.c
Moving randconfg, all*config support to aconf.c
allowed conf.c to be cleaned up.
While cleaning up conf.c the chatty oldconfig mode
was killed and conf.c is now only used for two purposes:
make config:
Interactively ask for each config option
make oldconfig
Interactively ask for each new config option
We now check for valid stadin in both cases and this
may break a script here and there.
