* The boot loader (bios_ia32 only) now duplicates everything that goes to the

serial output, and puts it into the new kernel_args::debug_output field.
* syslog_init() will now check if there is anything in kernel_args::debug_output
  and will put that into the syslog buffer.
* dump_block() now also prints an offset.
* Fixed warning in mmu.cpp.
