refactor: eliminate the getunitpeasants global variable.
bugfix: it was possible to uncover stealth units with GIVE CONTROL.
remove the deprecated getunit function.
fix the build, missing return value from give_control_cmd.
add the test coverage for getunit.
fix a bug where NULL was not returned when unit is in the wrong region.
remove support for versions prior to turn 572 (INTPAK_VERSION).
reading anything prior stopped working some time ago, let's not kid ourselves.
nobody needs to read those datafiles, they are more than 7 years old.
less code is better.
if access to these files is needed, check out an old version from source control.
remove even more obsolete datafile version support.
remove the obsolete dungeons module.
I don't think this has ever been used, and it has fallen victim to entropy since it was first written. good riddance!
merge failure, try again.
move chaos to a separate module (it is an old E2 feature)
remove some inactive #define macros and the code that goes with them.
mostly rules that were experimental, but have made it into common use (not worth the effort of making them configurable).
