* Renamed cpptest.h and cpptest.cpp to cpp.h and cppmain.cpp respectively.
* Renamed cppmain() to enter_cpp() and its duty now to provide a wrapper for the real cppmain(). It just wraps it with call_ctors() and __cxa_finalize().
* Added copyright notice to cppmain.cpp.
* Made the iso image path in bochsrc relative.
* Removed parallel port support from bochsrc because it caused a nag screen to show in bochs.
* page_table_entry is now unsigned long instead of long.
* Added printk() logging to control how many messages appear on the screen. That required moving the real impl of printf into print0 and now printf is just a wrapper around print0. That was needed to support transitive variable-length-arugments passing between several functions (printk should have wrap printf, no way to do it without supporting that).
* Converted most usages of printf() to printk() with respective log level.
* Fixed some signed/unsiged comparison compiler warning messages.
* Commented SHOW_STAT_FAILED calls.
* Cleaned cpp_rt_support.c a bit. Added some useful comments about the __cxa_XXX functions. And repositions some comments to be put in more relavent places.
* Renamed some stuff in the cpp_rt_support.c file, to confrom to the newly read Itanuim C++ ABI http://www.codesourcery.com/cxx-abi/abi.html :).
* The make clean command now deletes *.o and *.d in seperate commands because, if no *.o is present, no *.d would have been deleted ! That's because rm would produce an error that no *.o is present and ignore deleting *.d !
* Made the path relative in run.c (build environment change).
