Use uintptr_t instead of addr_t
...
They're never actually going to change independently, and it's also
brining in kutil headers more places than they should be.

APIC timer calibration
...
Now the APIC timer is calibrated against the PIT, and the interval for
timer_enable takes a number of microseconds instead of raw ticks and a
divisor.

Getting rid of 'boogity!'.. end of an era.
...
Since I'm doing a lot of work on task scheduling, 'boogity!' simply
isn't the "we're all good and we're done!" message that it used to be.

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.

- 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

_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.
