Change: Decouple and remove landscape-dependent cargo types. (#11719)

Cargo types of default engines, industries and houses are now specified in terms of label.

Codechange: Use consistent name for bay road stops

As of #10494, this is how we describe original dead-end road stops.

Fix #10334: Store separate newgrf-safe version of date_of_last_service. (#11124)

This value is not changed when the date cheat is used, which caused issues with changing properties based on service date.

Codechange: automatic adding of _t to (u)int types, and WChar to char32_t

for i in `find src -type f|grep -v 3rdparty/fmt|grep -v 3rdparty/catch2|grep -v 3rdparty/opengl|grep -v stdafx.h`; do sed 's/uint16& /uint16 \&/g;s/int8\([ >*),;[]\)/int8_t\1/g;s/int16\([ >*),;[]\)/int16_t\1/g;s/int32\([ >*),;[]\)/int32_t\1/g;s/int64\([ >*),;[]\)/int64_t\1/g;s/ uint32(/ uint32_t(/g;s/_uint8_t/_uint8/;s/Uint8_t/Uint8/;s/ft_int64_t/ft_int64/g;s/uint64$/uint64_t/;s/WChar/char32_t/g;s/char32_t char32_t/char32_t WChar/' -i $i; done

Cleanup: Remove unnecessary VehicleRandomBits()

Simple Random() assignment to byte does the same.

Fix: do not update a RV's Z-position when stationary while turning

When the direction of a RV changes the Z-position update logic was called,
which did nothing to the Z-position because that is only changed every other
step. By chance/luck this never triggered with RV's turning around, until
making the partial Z calculations consistent and moving the locations where
the Z-position is changed, causing the Z-position to be changed twice for
the RV that stayed at the same location.

Codechange: pass "ground vehicle" to GetTileSlopeZ since for tunnel/bridges there are two states

Previously it checked the position in non-driving direction to "guess" whether
a ground vehicle was using the function, so on tunnels/bridges it could either
return the Z of the (virtual) ground compared to the Z of the path the vehicle
would take.

Change: Use power-of-2 scaling for some dimensions in GUI.

These are related to drawing sprites that are normally drawn on the
landscape, and should therefore still follow power-of-2 scaling to fit
correctly.

Codechange: Template DoCommand to automagically reflect the parameters of the command proc.

When finished, this will allow each command handler to take individually
different parameters, obliviating the need for bit-packing.

Codechange: Let the compile generate the master command table out of templated command traits.

This is using a non-intrusive type-traits like templated system, which
allows compile-time validation that the command table and the command
enum match up.

Fix #7611: keeps news about accidents around after vehicle is cleaned up (#8497)

When a vehicle is cleaned up, all news that points to the news is
also removed. This was a bit evil, as it would also remove any
news related to crashed, acting like the crash never happened.
This left players a bit in the dark what was going on exactly.

Feature: Framerate display window (#6822)

Frame rate and various game loop/graphics timing measurements and graphs. Accessible via the Help menu, and can print some stats in the console via the fps command.

Change: Remove direction parameter from Vehicle::UpdateDeltaXY. (#6792)

The value is either unused or always the same as this->direction.

(svn r27814) -Change: Remove _roadveh_depot_exit_trackdir

_roadveh_depot_exit_trackdir was just a copy of
DiagDirToDiagTrackdir. (cirdan)

(svn r27813) -Change: Remove _road_enter_dir_to_reachable_trackdirs

_road_enter_dir_to_reachable_trackdirs was just a copy of
DiagdirReachesTrackdirs. (cirdan)

(svn r26118) -Fix-ish?: comparing the old Direction to the possibly new state containing a TrackDir... well comparing apples and pears. Occasionally they would be the same and occasionally not; at least without any logic behind it.
Since the occasions that the false branch was taken never resulted in a bug report, I highly doubt that removing it completely affects anything... except the visual speed of cornering in a numer of corners (<50%) and visual speed in an old style road stop.
