Add optional check for bad kernel-doc comments
Implement a '-none' output mode for kernel-doc which will only output warning messages, and suppresses the warning message about there being no kernel-doc in the file. If the build has requested additional warnings, automatically check all .c files. This patch does not check .h files. Enabling the warning by default would add about 1300 warnings, so it's default off for now. People who care can use this to check they didn't break the docs and maybe we'll get all the warnings fixed and be able to enable this check by default in the future.
