Replaces g_splitscreen.c with g_party.cpp. Simplifies
party management functions.
Moves externs out of already bloated doomstat.h and
g_game.h into g_party.h.
Cuts down on globals spam.
This used to be used for `P_RelinkPointers()`, but was superseded by the far saner mobjnum. HOWEVER, its lingering effect was to leave `mobj->info` in an invalid state until a later `P_FinishMobjs()` was called. This is memory unsafety :D
After removing the last remnants of this ancient hack, it is now once again possible to connect to a server without crashing immediately. However, I did get a crash after a few seconds, so there is definitely still *something* nasty going on under the hood.
* Instead of doing constant G_MapNumbers when finding the relationship between maps and cups...
* Add a cache of level IDs to cups, to go with the strings.
* Add a cache of the cup pointer to maps, so we don't have to search through all cups to find our map. (done in P_InitMapData)
* Pre-emptive work: G_IsSpecialStage and P_GetNextEmerald now reference cup data instead of a hardcoded ID set.
* Remove a bunch of old stuff from mapheaderinfo_t/associated, and reorder what stays
* Countdowntimer? 💥
* Startrings? 💥
* sstimer/ssspheres? 💥
* forcecharacter? 💥 (distinct from forceskin)
* interscreen? 💥
* sstage_start/end and smpstage_start/end? 💥💥💥💥
* You've been blocked
* G_MapNumber now returns a special NEXTMAP_INVALID if not found, for more consistent reference.
* Incorporate a good chunk of the `edit-headers` branch. Can't clear maps individually because of the new restrictions on sequential mapheaders, but we can add a "disable in vote screen, not even for map hell/archive" flag to a map at some future juncture for equivalent functionality...
Also:
- improved error prints for SOC condition definitions
- improved bounds checking to use `nummapheaders` for iterating over mapheaderinfo
There are still situations that use NUMMAPS like mapvisited, randmapbuffer, etc, which need to be addressed before merger.
* Register cv_netdemosize so it actually works
* Replace all the raw Z_Frees on demobuf with the appropriate function
* Free demobuf in G_CheckDemoStatus (yay, no more buffer == NULL asserts)
* ...allocating a buffer of uninitialized length? what
The idea is to return it as a meter item while keeping and putting a restriciton on the speed building and storing part from the previous version. Using the boost while its active will drain time from the main timer to fill up store as it were, this store is what handles the boost duration which caps at 2 seconds. The speed increase from using the flame shield more and more now diminishes and caps around 81 fu/t on knuckles for example and is done seprately from the main drain timer and the store.
