- Raise the player limit to 8.
- Remove the logic that forces player counts up/down when switching
between cooperative and deathmatch game modes.
- Add heuristics to add start positions for the extra players, since
standard maps will not have the required number of starts.
Add macro cf_assert ("control flow" assert) to hint to gcc that certain
conditions are impossible. Use it to avoid generating range checks for
situations that never happen. If the event did happen, the only
consequence would be truncated UI text, rather than a correctness
problem.
Various functions are preprocessor-excluded by `BOTTOM_STUFF`, which has
been 0 since btb added it in a196e6d554
(October 2001). It seems unlikely that anyone will miss it.
Rather than use an inline wrapper and rely on the compiler optimizer to
redirect gr_set_current_canvas(nullptr) to gr_set_default_canvas,
rewrite all relevant calls directly in the source.
git grep -l 'gr_set_current_canvas' | xargs sed -i -e 's:gr_set_current_canvas(\s*NULL\|nullptr\s*);:gr_set_default_canvas();:'
This code was part of a feature abandoned before retail. It cannot be
usefully used in campaigns. Remove it to reduce code size and simplify
later changes.
Editor groups write `struct segment` to a file in raw form, but had no
code to enforce that this raw form remained stable over time. Various
changes to `struct segment` have repeatedly changed its internal
structure. Each change created an incompatible dialect of the editor
group file, and all the dialects share the same version number.
According to
```
git log -p -L'/struct segment {/,/};/:common/main/segment.h' HEAD --not 0.58.1-d1x 0.58.1-d2x --
```
`struct segment` changed layout in:
* d1c6b89f17 ("Move dsx::segment -> dcx::segment") [D1 only]
* 596ecbb38d ("Rename segment::value to segment::station_idx") [D1 only]
* 6f10a67c09 ("Move segment::sides to end")
* c53b734abb ("Compute slide segments early") [D2 only]
* 40e90fea22 ("Move Light_subtracted[] to Segments[].light_subtracted")
* a65d774c83 ("Improve packing of struct segment")
* c70c6c98b3 ("Remove obsolete segment::degenerated flag")
Mark editor groups as broken to avoid making the mess worse. If anyone
cares about group support, it needs to be rewritten not to depend on the
internal layout of `struct segment`.
`value` is generic and unclear. It is always meant to be used as an
index into the Station array, so rename it `station_idx` to show this.
Define and consistently use `station_none` to represent that no station
is assigned.
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
are manual. All other changes are generated by:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\(v\?\)\(\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/\1m\2/g'
for the 'm' prefix and:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\([cm]\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/i&/g'
for the 'i' prefix.
For switch cases where existing comments or code flow logic obviously
intended to fall through, add a gcc-7 /*-fallthrough*/ comment to
silence warnings about this. Some cases which are less obvious are not
converted, so the code does not yet compile clean with
-Wimplicit-fallthrough.

clang becomes confused trying to determine which vm_distance_squared
constructor to use for a literal input of 0x7fffffffffffffff, even
though the size of the input requires it to be `long` and only one
constructor can take a `long`. Switch from an explicit
0x7fffffffffffffff to the symbolic constant INT64_MAX, which has the
same value, but a platform-appropriate suffix to force the compiler to
pick the right type.
For general clarity, switch some other instances of integer maximum
literals to symbolic constants of the same value.
This commit has no effect on the generated code (except for changes to
line numbers).

Fixes: 17208cca79 ("Disallow int for vm_distance_squared")
Contains 2 calls - to obj_create and init_ai_object. For safety reasons and tidiness compared to using obj_create directly. The call to init_ai_object in recreate_thief was already redundant.
This preserves virtually all game information, including active fire. The saved game 'gamesave.sge' can also be loaded with File->Restore Game State. The level can still be saved as usual (but it warns the user if there's an unsaved game state). This functionality may be useful for testing (or cheating! ;) )
When File->'Play in 320x200' is chosen, use StartNewGame(Current_level_num). For now use create_new_mission and Current_level_num = 1 every time. Also remove the now redundant hacks GM_EDITOR and editor_reset_stuff_on_level.
If a game was playing, continue playing. If it was in the main menu, return to the main menu. (If all files are put in place the editor can load again.)
When responding to EVENT_WINDOW_CLOSE, set MainWindow to nullptr - fixing multiple issues with these dialogs including the inability to re-open them and a crash on exiting the editor.
One caller uses fuelcen_activate when segp->special != station_type.
Every other caller passes the type that was already on the segment.
Move the assignment into the one caller that needs it, then remove the
argument.
This ensures the event system will know what's going on. Also remove the 'likely' branch prediction macro from close_wall_window because close_wall_window will only be called outside of the wall dialog's handler (to open a different dialog or close the editor).
Conflicts:
common/arch/sdl/window.cpp - Remove unused EVENT_WINDOW_CLOSED and w_callback local var
common/ui/dialog.cpp - Remove unused EVENT_WINDOW_CLOSED
Replace delete dcx::window kludge with a better solution: instead of requiring every handler to delete the window, add a window_event_result::deleted, which gets returned if the window was deleted by the handler, so window_close knows not to attempt to delete it again.
Allow dcx::window struct to be subclassed step 3. This step adds the window destructor and both requires and implements the window to be deleted by the event handler/client in all cases.
Save unique_ptr's to UI_GADGET_BUTTON's in similar/editor/med.cpp and similar/editor/medwall.cpp. Fixes compile errors and resolves a crash when attempting to access both dialogs' gadgets (input event processing is the first attempt).
Rename symbol OGL to DXX_USE_OGL to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were
manual.

Field width conversion `.*` always takes an `int`.
On Win32, casting `long` to `int` triggers a `-Wuseless-cast` warning.
Omitting the cast works correctly.
On Linux/amd64, casting `long` to `int` works correctly.
Omitting the cast triggers a `-Wformat` warning.
Add a macro that conditionally expands to `static_cast<int>` or to ``,

C casts do not require parentheses. C++ casts require grouping around
the target. Prepare for conversion to C++ casts by adding otherwise
