Add a simple API implementing a heap memory area.
This specifies 2 main data structures:
struct heap - Defines a heap:
Holds a table with all entries in the specific heap and
the initial heap memory address
struct heap_table - Describes the usage state of every PAGE
within the specific heap.

won't build without these helpers.
They are used for now mostly to setup PICs.

This has only been working so far because vga.h was included only
on source files already including stdint.h.
We should put it direct to the header file

organized.
Ah, yeah, OS name will be renamed to ToxicOS

Create the kernel.c file and its initial start_kernel(), and
jump to it from the ASM.
Also setup the build system to actually build it
