Nigel b07b4f0d38 Moving certain aspects into their own static library
Problem:
	As our kernel grows we need more complex datastructures and functions these would come from
	the standard C/C++ library with normal programs.
	The kernel is a freestanding programme and has no access to standard libraries.

Solution:
	We build a mini version of the standard C/C++ library which will contain the
	datastructures and functions we want. This library can then be statically linked
	into our kernel binary.

	Making it a statically linked library also gives more structure to the project.
	Keeping these random functions and datastructures in the kernel just clutters the
	kernel source code with less relevant source code.
