Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

-# diffconfig - a tool to compare .config files.

-
-Diffconfig is a simple utility for comparing two .config files.
-Using standard diff to compare .config files often includes extraneous and
-distracting information. This utility produces sorted output with only the
-changes in configuration values between the two files.
-
-Added and removed items are shown with a leading plus or minus, respectively.
-Changed items show the old and new values on a single line.
-
-If -m is specified, then output will be in "merge" style, which has the
-changed and new values in kernel config option format.
-
-If no config files are specified, .config and .config.old are used.
-
-Example usage:
- $ diffconfig .config config-with-some-changes
--EXT2_FS_XATTR n
--EXT2_FS_XIP n
- CRAMFS n -> y
- EXT2_FS y -> n
- LOG_BUF_SHIFT 14 -> 16
- PRINTK_TIME n -> y
