Simple vcpkg Overlay Ports Setup

The file vcpkg-configuration.json uses an existing vcpkg as the default registry; this assumes vcpkg as a git submodule. The baseline value is the commit hash of the vcpkg submodule. Update the hash as needed to reflect the actual version of the vcpkg registry you've got checked out as a submodule.

Overlay Ports

Use a directory vcpkg-overlays to contain the overlay ports;

Disassemble an Object File with MSVC Linker

There are undocumented switches to the linker that will disassemble an object file:

link /dump /disasm /linenumbers /out:foo.asm foo.obj

Case Study

Our case study is the open source fractal generator Iterated Dynamics, a fork of FRACTINT.
This is a 30 year old code base that started as a 16-bit MS-DOS program written in C and 16-bit x86 assembly.
The code base has contributions from many, many authors over the years.
Source formatting and identifier conventions are varied due to the large number of authors.
Source code organization has been tortured by the constraints of early MS-DOS programs operating in a limited amount of physical memory and the use of overlays.
Conditional compilation was sprinkled throughout to enable various debugging facilities or experiments in alternative implementations.
As C does not have inline functions, there are some places that heavily use preprocessor macros.
Some of the functions are [exceedingly long*](https://github.com/LegalizeAdulthood

	A colleague discovered that switching from `-stc=c++17` to `-std=c++20`
	in their project resulted in a different behavior from some associative
	containers. A bit of research allowed to narrow down the culprit to what
	can be demonstrated by the following minimalist example

	constexpr auto jsv = R"({
	"feature-x-enabled": true,
	"value-of-y": 1729,
