Codechange: Rename and move SpriteGroup-specific cargo types into a namespace.

These 'cargo types' have special defined uses and must not be used elsewhere. This makes it clearer that they are special.

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.

Change: Store station blocked/wires/pylons flags in map. (#11337)

This stores three flags in unused map bits, and avoids having to look up
station graphics and custom station specs to determine blocked/wires/pylons
status.

This potentially affects rail pathfinding performance.

Savegame version is not bumped, as the flags can just be updated every
time.

Codechange: cleanup CargoPacket in terms of variable/function names (#11278)

Over the years, things got reused and changed, making the current
names somewhat unclear in what they actually mean and do.

Codechange: make explicit when a TileIndex is cast to its basetype (#11190)

This prevents people accidentially assigning a TileIndex to a Date
or any other type they shouldn't.

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

Codechange: Use IsValidCargoID/IsValidCargoType.

IsValidCargoType() is used only for unmapped IDs.

Codechange: Use std::vector for station speclist

This removes manual memory allocation, although we still manage the list
size in roughly the same way.

Cleanup: [NewGRF] Callback 14 used a weird value for var10 in the GUI.
The value 0x2110000 probably originated from a mixup between callback 14 (sprite layout) and 24 (tile layout).
The latter does indeed use a var10 value like that.

Feature: NewGRF callback profiling (#7868)

Adds a console command newgrf_profile to collect some profiling data about NewGRF action 2 callbacks and produce a CSV file.

(svn r27928) -Fix: [NewGRF] While executing random triggers, var 5F should include the new triggers.
-Fix: [NewGRF] Reset used random triggers only after all A123 chains have been resolved, so that all RA2 in all chains can test the shard triggers. This also includes multiple RA2 in the same A123 chain.
-Fix: [NewGRF] Industry random triggers are stored per tile, even when randomising the shared random bits of the parent industry.
