Run indent script on all c source files.

Change style to KNF for readability.

I'd rather not debate about the superiority of indent styles like a little girl. Here's the hard truth: Running the original banner-style `indent-all.sh` against e3d8eb3 produces a bunch of changes. This leads me to believe that there isn't a serious attachment to a particular indent style (if there was, it wasn't enforced well). In fact, indenting using the `--style=knf` argument leaves a number of source files untouched!
