* The savegame system.
*
* =======================================================================
*/
/*
* This is the Quake 2 savegame system, fixed by Yamagi
* based on an idea by Knightmare of kmquake2. This major
* rewrite of the original g_save.c is much more robust
* and portable since it doesn't use any function pointers.
*
* Inner workings:
* When the game is saved all function pointers are
* translated into human readable function definition strings.
* The same way all mmove_t pointers are translated. This
* human readable strings are then written into the file.
* At game load the human readable strings are retranslated
* into the actual function pointers and struct pointers. The
* pointers are generated at each compilation / start of the
* client, thus the pointers are always correct.
*
* Limitations:
* While savegames survive recompilations of the game source
* and bigger changes in the source, there are some limitation
* which a nearly impossible to fix without a object orientated
* rewrite of the game.
* - If functions or mmove_t structs that a referencenced
* inside savegames are added or removed (e.g. the files
* in tables/ are altered) the load functions cannot
* reconnect all pointers and thus not restore the game.
* - If the operating system is changed internal structures
* may change in an unrepairable way.
* - If the architecture is changed pointer length and
* other internal datastructures change in an
* incompatible way.
* - If the edict_t struct is changed, savegames
* will break.
* This is not so bad as it looks since functions and
* struct won't be added and edict_t won't be changed
* if no big, sweeping changes are done. The operating
* system and architecture are in the hands of the user.
