fixing issues
1) main.c: order of init (multiboot.c must be after heap & paging
because it uses heap to allocate pages for framebuffer)
2) paging.c: zeroing new pages allocated via heap
3) multiboot2.c: invalid pointer arithmetic
4) libk/string.c: check for null pointers in memcpy
5) paging: only page_lvl2 should have FLAG_HUGE
6) keyboard.c: kfree(print_buff)
