Make printk() log to a buffer. This only works with qemu for now, but there it works really well.

A few side benefits of this patch: - printk() now works directly after printk_buffer_init(), even before the serial port is set up. - If all you want is a log, you don't have to bother with serial output. - A payload can read and analyze the log. - You can build on this and buffer log until serial is available, then flush the messages buffered so far.
