Subject: Make the build system create a sysfont.h which includes font
 information for the system font. Available #defines are: SYSFONT_NAME,
 SYSFONT_FACENAME, SYSFONT_WIDTH, SYSFONT_HEIGHT, SYSFONT_SIZE,
 SYSFONT_ASCENT, SYSFONT_DESCENT, SYSFONT_FIRST_CHAR, SYSFONT_LAST_CHAR,
 SYSFONT_DEFAULT_CHAR, SYSFONT_PROPORTIONAL, SYSFONT_COPYRIGHT,
 SYSFONT_BITS_SIZE.

Also fix a small bug in the iPod bootloader printf() code and use printf() for PortalPlayer bootloaders too.
