593cda3ee8 Convert page_block to use kutil::linked_list 
- Created a new linked_list-based slab allocator
- Simplified memory bootstrap code by using the slab allocator and
  linked_lists

e7a509176d Move makerd to TOML-based manifest 
Added the cpptoml library (and license), and moved to using that for
the initrd manifest. It's now possible to specify the `executable`
flag for files, and the kernel correctly only launches new processes
for the initrd files marked `executable`.

585abe9a18 Simple ELF program loader 
Now any initrd file is treated like a program image and passed to the
loader to load as a process. Very rudimentary elf loading just allocates
pages, copies sections, and sets the ELF's entrypoint as the RIP to
iretq to.

1758ee4215 Initial ramdisk support 
- Create initrd library to support definitions and loading
- Allow tools compiled for the host machine to be built by wscript
- Create makerd tool to build initrd from manifest
- Move screenfont to initrd, so don't load framebuffer initially

d5b8902d8f Moving the rest (except ACPI tables) to high mem 
Also the debug messaging to verify it.

799fbbdd10 _Actually_ move the kernel to the last TiB. 
More work on process page tables, including only mapping the last 2 pml4
entries (the highest 1TiB of the address space, ie, kernel space) into a
new table.

Includes the work of actually moving the kernel there, which I had
apparently done in name only previously. Oops.

57abb03deb Rearrange memory manager into two classes. 
page_manager and memory_manager are now separate, and are also pre
allocated in the kernel so they don't have to allocate themselves.
