Codechange: Add HasFlag() to test if a value is present in a bitset enum type. (#12959) 
This simplifies tests for `(x & y) != y` with enum classes by reducing repetition, similar to HasBit(), and also makes the intent of the expression clearer.

952d111b94 Codechange: Split CT_INVALID into CT_INVALID and INVALID_CARGO. 
INVALID_CARGO is a CargoID and should be used for most purposes in game.
CT_INVALID is a CargoType used for defining default properties.

Fix: Calculation of initial engine age was inaccurate. (#11660) 
Engine age in months was calculated as the difference in days / 32, instead of the actually difference in months. This would result in engines being artificially younger if a game was started at a later date.

Codechange: Add base() method to StrongType to allow access to the base type without casting. (#11445) 
This removes the ability to explicitly cast to the base type, but the requirement
to use .base() means the conversion is still explicit.

Fix: Check for engine variant loops during NewGRF initialization. (#11343) 
Invalid NewGRFs could set up an engine variant loop that never ends. This
was checked for in some places that evaluated variants, but not all. In
most cases this would result in the engines not appearing, but could
potentially cause an infinite loop and crash.

Instead, during NewGRF initialization detect loops and remove invalid
variants before setting display flags.

bf9caa425b Change: Units-system can convert from N to kN, don't preconvert. 
This allows force to passed as is and avoid premature rounding.

The AI function "GetMaxTractiveEffort" still needs to return kN to avoid breaking the API.

Fix: [NewGRF] Default value of RailVehicleInfo::railveh_type was inconsistent with other default properties. (#9967) 
If a NewGRF assigned neither "power" nor "dual-headed" properties,
then "railveh_type" defaulted to "singlehead-engine", while "power=0" said "it's a wagon".
