Removing system dependencies

[trgwii]

The main goal of doing this is to make the project easier to build on various
platforms, easier to debug, and overall more stable.

Relying on system dependencies is implicitly the same as relying on your
specific OS. I don't know which OS was originally used to develop ivm-apps. I was told it was "some version of Ubuntu".

For my host and Docker container versions, I am using Debian 12.7 (Docker image
version:
debian:12.7-slim@sha256:36e591f228bb9b99348f584e83f16e012c33ba5cad44ef5981a1d7c0a93eca22).

The dependencies and versions I had to install are listed here:

Name	Version	Description	Remove?
autoconf	2.71-3	autotools (also includes automake), creates scripts out of ./configure.ac templates	See Replacing autotools
bsdmainutils	12.1.8	hexdump command needed by ivm-fs used in ROAEshell, this should be replaced with custom code	✅
build-essential	12.9	gcc, ar, ld, other compiler tools	❌
check	0.15.2-2+b1	C test library used by boxing, this should be replaced with custom code or vendored	✅
dotnet-sdk-7.0	7.0.410-1	Needed to build ivm-implementations (F# emulator)	✅ (remove ivm-implementations from this repo)
file	1:5.44-3	Needed by various autotools build scripts? Unsure. Should probably be removed	✅
gawk	1:5.2.1-2	Needed by various autotools build scripts? Unsure. Should probably be removed	✅
git	1:2.39.5-0+deb12u1	Needed to clone sub-repos, required, but code should switch to submodules or something similar	❌
imagemagick	8:6.9.11.60+dfsg-1.6+deb12u2	Needed by testdata repo to convert images, should be removed, converted files can be committed	✅
libpng-dev	1.6.39-2	Needed by yet-another-fast-ivm-emulator to read and output png's	✅ (externalize the dependency on an emulator)
pkgconf	1.8.1-1	Needed by build to get include paths from libraries, maybe removable if autotools is replaced	✅
texlive-full	2022.20230122-3	Needed to convert LaTeX to PDF in ivm-doc	✅ (just remove ivm-doc from this repo)
unzip	6.0-28	Needed to unzip zlib and libjpeg downloads from websites	✅ (find git mirrors to use as submodules?)
xxd	2:9.0.1378-	Needed by testdata to generate C header files from binary files, replace or vendor	✅

Most of these are unnecessary and are just shell-utilities used by the build
scripts defined in autotools. Others are only used to generate documentation and
are not very relevant.
