This completely restructures the database of terminal types, putting each terminal in its own file. We also compress the database files, and use infocmp instead of trying to use the C level API. The mkdatabase script will rebuild the entire database from the terminfo files on the system. Individual entries can also be built by simply running the mkinfo program with the terminal type.
