The .config saves your most recent options, .config.old is a backup of the
.config you have previously, before you ran 'make config', 'make
menuconfig', or 'make xconfig' the most recent time.

If there is a .config in that directory, it is used by default.  I'm not
sure how you would tell the configuration programs not to use it.  I just
move it or remove it if I want to start from scratch.  Do note that
when you upgrade your kernel, you don't want to use the old .config file
directly, as some things may have changed; instead, you put the .config
from the previous version in your source directory and run a 'make
oldconfig' to pick up just the things that have been added or changed.
(This is for when you're using the .config from a previous kernel.)

Yes, .config is a standard Linux convention.
