Start implementing read and write support in tmpfs
...
write seems to work fine, read just hangs there, waiting.

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.

Forgot to add break :)

And that, is why you test before pushing and commiting >.<

Kernel, libc: Implement %p in *printf()
...
So we can avoid writing (unsigned long)ptr or (uint64_t)ptr everywhere when wanting to print a pointer.

Finally, a text renderer that actually works. We can now see the kernel messages without a serial port :)

Finally implement %l and %z format modifiers
...
Finally, we can use %zx with a 64-bit number instead of %x%x with 2 32-bit values split from a 64-bit number!
