3a310f1802 Codechange: Store GRFConfig parameters in a vector. (#13137) 
All GRFConfigs have space allocated for parameters, but only configured GRFConfigs need them.

Using a vector instead means that space is only used when parameters are used.

177e2ebf80 Codechange: Support saveload of reference vectors. 
This uses the same data format as reference lists, but for vectors, so allows data structures to be changed without affecting savegame format.

059a4b22f7 Codechange: Use projection-based std::range::find where possible. 
This simplifies matching by class members and avoids wordy lambdas.

16038879e4 Codechange: Speed up industry generation using industry-type checks. (#13094) 
Store a list of industries per industry type. This allows industry generation checks which only consider a specific industry type to check a reduced set of industries, leading to a potential performance increase.

This also removes the need to track industry type counts as well.

c39810ff6a Codechange: Replace path cache queues with vectors. 
Ship and RoadVehicle path caches use a std::deque, which is quite memory hungry, especially for RoadVehicle which has two.
std::deque was used to be able to push/pop from either end.

Change to use a single std::vector each, which is now push/popped from the back.

8f9836793f Change: Store water tile flooding state in the map. 
This allows water tiles which cannot flood any further to not even try to flood.

On a large map with lots of water tiles this can noticeably reduce game loop processing time.

Mostly ported from JGRPP.

3b6d3080f2 Add: Apply rail/road type conversion when NewGRFs are updated mid-game. 
This will update the rail/road type of tiles on the map, taking account of tram state, if types are moved around.

8bb6572943 Add: Implement missing road type label conversion. 
This was implemented for rail types but missed for road types.

This lets road type labels to be reordered, allowing for upgrades of NewGRF.

157d028915 Codechange: Simplify testing for railtype map conversion. 
Build the list of railtype conversions at the same time as testing if conversion is needed.

This avoids having two similar loops which need to compare the same things.

db1a1c5dd9 Change: Invalidate build toolbars when NewGRFs are changed. 
If NewGRFs are changed while a rail or road toolbar is open, the toolbar could refer to an invalid rail/road type. If so, close it.

f19829d029 Fix #12831: Delay vehicle cache init to after map upgrades in load

valid map is now performed later in the load process.

d5671030b1 Codechange: Add NewGRFSpecsBase class to hold class/index information. 
Standardises how the class index is stored in the spec, instead of relying ot the Spec structs having the same members.

This allows retrieving class_index and index without searching or using pointer arithmetic.

'cls_id' is renamed to 'class_index' to make it clearer that it is an index rather than the multichar label of the class.

115ac2629b Cleanup: Remove TileMatrix that hasn't been used for 4+ years. (#12621) 
This 'nice' structure was left around from #8258 just in case it might be used again.

Spoiler alert: it hasn't.

This removes manual memory management. And otherwise unused and untested code.

26bb87ebf1 Codechange: Replace SaveLoad var length arrays with switch block and sizeof. (#12570) 
SlCalcConvMemLen(), SlCalcConfFileLen() and CalcOldVarLen() follow a pattern of looking up part of a value in an array.

These function returns the size of bytes of a variable type, but is not very clear. Replace with a switch block instead.

Removes lengthof, array indices, and magic numbers.
