Kernel, libc: Fix a big bug in printf()
...
Every time printf flushes the buffer to us in sprintf() or snprintf(), we call strncat to append the data.
But we want to start from the beginning in the first flush. What if there was data already there?
Well, we just append to the old data. Which is not good, and breaks snprintf()'s maximum size policy.
This fix sets the first byte of str to NULL, to avoid this.

Kernel: Use framebuffer virtual address instead of physical address
...
Just found out bootboot.fb_ptr was the physical address, not virtual.
That explains why we were getting page faults while writing to the physical address of the framebuffer. (we were in a user address space when doing so)
So this should probably make the system much more stable!!
