Under the new versioning scheme when a new branch is forked the
major version number will be reset. The minor version number will
now be used to mark a release as containing backwards compatible
additions and the patch version number will be used to mark a
release as containing just bug fixes.
- INSPIRCD_SOCKETENGINE_NAME is not really something that needs to
be user facing. If opers want to know this kind of internal info
then they can look at the build configuration.
- INSPIRCD_SYSTEM causes problems for reproducible builds and is
only accurate for the state of the system when InspIRCd is built
which is not useful in the slightest.
