add a trivial patch style checker
We are seeing increasing levels of minor patch style violations in submissions to the mailing lists as well as making it into the tree. These detract from the quality of the submission and cause unnessary work for reviewers. As a first step package up the current state of the patch style checker and include it in the kernel tree. Add instructions suggesting running it on submissions. This adds version v0.01 of the checkpatch.pl script.
