Continuing to try and simplify the build system, calculate the remaining
two autoconf variables from the existing config.mak.
For the moment, leave a configure and configure.ac file in place to
allow any old build systems to continue to function without errors.
* Ensure all options start off for cmake too
* Attempt to make the build time config logic in the cmake process match the makefile process
* Add a simple muscle memory helper for cmake
* Ask them what they are smoking, then tell them to put it out
* Avoid occasional stale package cache errors
* Convert zstd feature to default disable
* All autoconf test use one standard template
To simplify the testing, cross-compilation and repeatable build process,
no configure options are automatically probed for - they all default to
off and are all using the same template.
The --with-x options should be deprecated and replaced with --enable-x
because there is no syntax checking for --with options in autoconf.
There are still some differences between the config options, but this
should provide a starting point.
* Remove unused code from the autoconf
* Remove warnings from default build
* Avoid calling port mapping functions if none are enabled
* Start with all builds in neutral config
* Add more missing code guards
* Adjust code guard location to placate cmake
The right number of commits to fetch is enough to be able to create
a `git describe` result - basically back until the most recent parent
annotated tag.
However, the github action/checkout@v2 only allows a simple number,
which is basically the answer to "how long is a piece of string"
