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

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

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.

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 #8810: "aircraft out of fuel" news was looking in the wrong place (#8832)

v->tile for aircrafts is always zero when in the air. Only when
it starts its landing (or take-off) patterns it becomes a sane
value.
So instead, base the news on the last x/y coordinates of the plane.

Fix #7619: nudge fast planes sooner towards their target (#8531)

For non-NewGRF planes, "count" is never above 1. So planes can
smoothly be guided to their destination. For NewGRF planes, they
can go as quick as "count" values of 20. This easily overshoots
the target. So, calculate if the plane will overshoot, and start
nudging him to the destination earlier. You won't notice this
either way, as it all happens within a single tick.

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.

Fix #8437: Planes landing at non-rectangular airports could be drawn at the wrong height

Only the rotated intercontinental airport, don't get excited

Change: [NewGRF] Use aircraft property 12 also for helicopters.
Due to keeping compatibility we can only do this for NewGRF-defined sound effects.

Codechange: fix Intel C++ Compiler linking issues.

GetAircraftFlightLevel<Aircraft> is only used in static functions
inside aircraft_cmd.cpp. With GCC, Clang and MSVC this is not an
issue, but on ICC fails linking, because it doesn't find this
version of this template. Possibly these two pieces of information
are linked.
Explicit defining the function fixes the issue.

Fix #6574: Remove go to hangar orders when rebuilding airport

When replacing an airport with another, cancel current orders of type 'go to depot' from aircraft still heading to it if the rebuilt airport doesn't have a hangar (helicopter vs heliport), or if the airplane can't land on the rebuilt airport (airplane vs helistation).

Removes 'go to hangar' orders from all aircraft when replacing an airport with hangar with another without hangar (heliport).

Fix #6574: Go to takeoff if no hangar

Sends the aircraft to takeoff if the airport it's currently at, got no hangar even if the order is to go to hangar.

Fix #6676: Prevent helicopters from stopping in midair during some kinds of landing

This adds a new flag that gets stored in the savegame, but it should still be compatible both ways, hence no save version bump.

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.
