Just adding some tex code for a book or more a place to put my thoughts and
whatnot when writing this "great" kernel. Might come in useful for someone at
some point.
Some CPU exception handling code, more handlers to come.
Adding some early initialization code for the jump from real to protected
mode. At the moment it isn't included in the build because some more complicated
directives have to be setup for it and this is quite involved to get setup. For
now the code is going in and I'll figure out how to piece it all together later.
Let's just go with Multiboot.

Make my life easier and rely on multiboot to drop us in 32 bit protected mode.
Converting loader.s to use multiboot.h
Assorted cleanup.
Clean up loader.S and multiboot.h
Removing this to unclutter the repo a bit
