Use wrappers to call the kernal in bank 15 instead of implementing kernal functionality within the cc65 libs (eats performance but is much smaller and simpler). Improved startup/shutdown code allows a return to the system bank without calling the BASIC cold start vector. git-svn-id: svn://svn.cc65.org/cc65/trunk@2793 b7a2c559-68d2-44c3-8de9-860c34a00d81
