Changed the PC-Engine's configuration file, so that the command line can build 8K, 16K, and 32K carts. Adjusted the PCE's document, the start-up code, and the PCE library test makefile. That makefile shows how to post-process the linker's output file.

__CARTSIZE__: type = weak, value = $2000; # $2000, $4000, or $8000
Renamed INITBSS to INIT and INIT to ONCE. The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name. Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.
