Implement an autosave subsystem and safer save handling, plus related UI and hooks.
- Add autosave state and logic (diablo.cpp): periodic timer, pending queue, priorities (Timer, TownEntry, BossKill, UniquePickup), cooldowns, combat cooldowns, enemy proximity safety checks, and helper APIs (QueueAutoSave, AttemptAutoSave, IsAutoSaveSafe, etc.).
- Integrate autosave triggers: queue on town entry (loadsave), unique item pickup (inv.cpp), boss kills (monster.cpp), and mark combat activity from player actions and hits (player.cpp).
- Add gameplay options to enable autosave and set interval (options.h/.cpp) and display countdown/ready label in the game menu (gamemenu.cpp/gmenu.cpp). Menu text retrieval updated to show remaining seconds or "ready".
- Make SaveGame robust (loadsave.cpp): write hero and stash via new pfile_write_hero_with_backup() and pfile_write_stash_with_backup() that create backups and restore on failure. Add utilities to copy/restore unpacked save directories safely (pfile.cpp) and adjust stash path handling signature.
- Minor fixes and cleanups: restrict mouse-motion handling to KeyboardAndMouse path, small reordering in player sprite width switch, and a few safety/formatting tweaks.
Autosave only runs in single-player and when IsAutoSaveSafe() conditions are met. Backup save logic attempts to preserve the previous save on failure.
This doesn't implement full sound support but stubs out most of the
sound code under SDL3, so that we can implement it piecemeal.
Implemented here:
1. Sound device initialization.
2. SVid sound playback.
Does not add a dependency on `SDL_mixer`: SDL3 built-ins
are enough to play SVid audio.
1. The char pointer returned by SDL is only valid temporarily,
keeping it around is not allowed so we copy the string.
2. Moves the trimming to DiabloUI. It now happens every frame
but that's OK here (not performance-sensitive and there is
little else happening on that screen).
In C++, globals initialization order accross translation units is not
defined. Accessing a global via a function ensures that it is initialized.
This will be needed for #7638, which will statically initialize change
handlers after the Options object has been initialized.
This mod renders a clock in the top-right corner
and is always available (disabled by default).
It is useful to have a mod available by default
as we work on mod support.
1. Moves more assets-related stuff from `init` to `engine/assets`.
2. Removes `SDL_audiolib` dependency from `soundsample.h`.
3. Cleans up some unused/missing includes.
Our implementation has a more modern interface and only
supports the features that we care about.
It always outputs `\n` as newlines and does not output BOM.
The modern interface eliminates awkward `c_str()/data()` conversions.
This implementation preserves comments and the file order of sections
and keys. New keys are written in insertion order.
We now also support modifying and adding default comments,
which may be a useful thing to do for the especially tricky
ini options (this PR doesn't add any but adds the ability to do so).
Sadly, this increases the RG99 binary size by 24 KiB.
I'm guessing this is because the map implementation generates
quite a bit of code.
Note that while it might seem that using `std::string` for every key and
value would do a lot of allocations, most of these strings are
small and thus benefit from Small String Optimization (= no allocations).
