78e5c71103 Deprecate the original fmap/funmap 
The cool thing here is that we're temporarily binary compatible with the
old stuff, so if anyone would use an old version of redox_syscall we can
easily find them with these prints.

4c009530a8 Make x86_64 log writer not use println!. 
This opens the door to completely elimnating println! usage from the
kernel.

dafd2e9f98 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.

03e60f7da6 Add log crate and add a generic logger. 
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.

efb5b47463 Implement Debug for a couple structs. 
I am finding it useful to be able to pretty print Mappers and
ActivePageTable structs.

Thanks to @4lDO2 for all this. I just moved his changes to io_uring onto
the master branch of the kernel. I take no credit.
