When I started in my copy, I removed a bunch of code and options that I
felt were distracting. I also renamed lots of elements like 'linux-cp'
and 'Linux CP' and 'Linux-CP' to just be 'lcpng'.
Now, rename all of this back, and make it ready for upstreaming.
The only diffs between my repo and upstream now are the includes and the
lcpng_interface.[ch] code changes, which is good.
