This avoids the need to explicitly set a logger early during boot, which
reduces the amount of moving parts that could go wrong slightly. And it
cuts the kernel image size by 13kb.
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.

This is the first step of integrating the log crate as the main way to
log messages from the kernel.
Also, reexport all log macros. This module should eventually be the
only logging API used in the kernel.
