Codechange: Use std::copy/fill pattern to initialize rail and road specs. (#11285)

This avoids use of lengthof and array indices.

Fix: don't compare next_station when trying to merge CargoPackets

For vehicle packets they shouldn't be compared, and for station
packets they are already in a bucket per next_station.

Feature: [NewGRF] Related Act2 objects for airports and airport tiles.

Airports are similar two stations and industries, both of which have the town as related object.
Airport tiles are similar to industry tiles, which have the industry as related object.
This seems a sensible structure, so let's make it Airport Tile -> Airport -> Town.

Add: [NewGRF] Inspection window for airports.

As as the station window combines all station types, accessing the
debug view is via the parent of the airport tile only.

Fix b0e73277: cargodist information got lost when splitting of cargo (#11280)

During b0e73277 we removed loaded_at_xy, but I kinda forgot that
it was a union with next_station. Now next_station wasn't copied
anymore, or checked in AreMergable.

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: Reduce size of TextEffectMode and TextEffectID.

TextEffectID was promoted to size_t in #9235, when it was used in loops.
However since then the relevant code uses range-for or iterators instead.

Codechange: Make INVALID_TE_ID a TextEffectID instead of a TextEffectMode.

Type-correctness?

Codechange: Don't allocate a text effect with INVALID_TE_ID.

Previously, despite INVALID_TE_ID existing, it was not checked during allocation and there was no limit to the number of text effects.

Codechange: Use std::find_if to find or assign a text effect slot.

This replaces an index-based loop.

Codechange: Use std::array for TemporaryStorageArray.

This removes the need for initialisation with memset().

Codechange: Use std::array and std::unique_ptr for PersistentStorageArrays.

This (mostly) avoids the need for manual memory management and copying.

Codechange: Using alias and std::array for company expense storage. (#11273)

This simplifies passing yearly expenses to functions and use of std algorithms.

Fix: asserts unintentially being partially disabled in release-builds (#11268)

The nlohmann-json header file includes assert.h, which rudely resets
the assert macro to what that header thinks is right. As we set the
assert macro to be active with release builds when WITH_ASSERT is
active, this means that every file including nlohmann-json has their
asserts disabled (for release-builds) but files that don't do no.

Let's avoid this issue, by telling nlohmann to not include assert.h.

Fix: Inaccurate waiting cargo total in station window when using cargodist (#11213)

For stations with many flows and/or small cargo packets,
due to accumulated inaccuracies in DivideApprox.

The displayed total should match GoodsEntry::TotalCount().

Codechange: Return update nwid_begin instead of count.

This avoids needing to keep track of how many widget parts have been consumed, instead we only to ensure nwid_begin < nwid_end.

Codechange: Use begin/end of nwidget parts of begin/length.

This simplifies processing nwidget parts as, unlike the remaining length, the pointer to the end of the list never changes. This is the same principle as we use(d) for tracking end instead of length for C-style strings.

And this removes 160~ instances of the lengthof() macro.

Codechange: Allow using more than 65536 NewGRF string IDs.

NewGRF string allocation allowed up to 524288 strings, however stringid was passed as uint16_t which limits to 2^16.

Change: Replace fixed length _grf_text array with vector.

Additionally reshuffle GRFTextEntry for better alignment.

This removes a mostly-unused static 20MB allocation.

Codechange: Reorder some high-use structs to reduce their size. (#11201)

This reduces GoodsEntry from 144 to 136 bytes (thereby reducing Station from 9704 bytes to 9192 bytes), and CargoPacket from 40 bytes to 32 bytes.

Codechange: workaround CMake/Xcode duplicate file name issue (#11186)

Having a library with files with the same name isn't supported in CMake's Xcode project file generation: https://gitlab.kitware.com/cmake/cmake/-/issues/20501. One of the files is renamed to work around this bug.

Codechange: add tests for GS <-> AdminPort JSON conversion (#11252)

While at it, fix a bug where booleans were made integers.

Fix: [Emscripten] config not saved on exit game (#11248)

When changing a Game Option and pressing Exit Game, the changes
were not actually stored. This because the post-mainloop code
was never executed for Emscripten.

Add: [CI] Create and store breakpad symbols for releases (#11247)

Additionally, also store PDB and exe files on the Symbol Server
for easier debugging with MSVC.

Add: calendar date for Survey results

This means no heuristics is possible on around which date people
play the game.

Change: [Win32] don't allocate 192KiB of memory on the stack on crash (#11240)

Heap is out of the question, as it might be corrupted.
Allocating this much on stack is silly.

So instead, allocate virtual pages to write the information in.

Change: mention in MacOS / Windows crashlog popup when files couldn't be generated (#11239)

For example, if the crash.sav couldn't be created, and the TryExcept
detected an issue, write out that the file is not available in
the popup.

Codechange: [MacOS] use backtrace() instead of our custom variant (#11233)

As mentioned in the comment, we only did it ourselves as we once
were compatible with versions before 10.5. But that time has long
gone. So let's update the code to a bit more modern approach.
