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`.

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.

Loading processes from within their memory space
...
The scheduler's create_process now sets up the stack to iretq into a
load_process function, which will load the process image into memory
from within the process' own virtual memory space. Currently this
loading is just copying the old 'taskA' function from kernel space.

Default to non-user in all kernel pages now

This causes the user tasks to just PF, so we'll need to actually have a
real loader now.

_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.
