loader: fix kernel text section ownership
...
The text section of the kernel should be owned by the kernel itself. Due
to a typo, only the last page of the text section was being marked as
owned by the text section.
This marks the remainder of the section as being owned by the kernel.

wip: working on getting message passing working
...
The goal is to get a basic message passing engine working that will also
function as a device that works on real hardware.
This is still reworking it to function correctly on a desktop system.
Once that is working, it will be reworked to function once again on
hardware.

loader: fix loading when init spans pages
...
Due to an issue withow MiniELF files were loaded, one page was mapped to
two addresses rather than having two adjacent addresses mapped. This
occurred when a small section spanned two pages.
This has now been corrected, and an additional test binary will be added
to demonstrate the issue.
