Add a way to customize how logging is done.
...
Each architecture may have a different method to enable logging. Now
that can be customized with a function passed to the init_logger
function.
Also, provide a minimal x86_64 implementation.
This is the first commit where you can see logging coming from the log
crate.

Wrap borrows of page table entries in unsafe.
...
This is safe because `Entry` is `#[repr(8)]` which is the minimum
alignment for qwords. Since the size of a qword is equal to that
alignment (8), they can also be borrowed from the array.
