Move hat-test into its own source file. I noticed while hacking on hat-test recently that it's quite awkward to be compiling a test main() program that lives in a source file also built into the Puzzles support library, because every modification to main() also triggers a rebuild of the library, and thence of all the actual puzzles. So it's better if such a test main() has its own source file. In order to make hat-test work standalone, I've had to move a lot of hat.c's internal declarations out into a second header file. This also means making a bunch of internal functions global, which means they're also in the namespace of programs other than hat-test, which means in turn that they should have names with less implicit context.
