Here's the plan about freeciv-3.0 savegame handling for which we've already been preparing during 2.6 cycle for example by introducing savecompat.[ch] module.

- savegame.c will be removed, dropping support for loading savegames older than those from freeciv-2.3
- savegame2.c will be copied as savegame3.c
- Saving part will be removed from savegame2.c, it happens in savegame3.c
- savegame2.c handles loading saves created by freeciv-2.3 - freeciv-2.6
- savegame3.c will load savegames created by freeciv-3.0 and later
- savegame3.c will be cleaned up accordingly (all the pre-3.0 compatibility stuff removed)

For division between savegame2.c and savegame3.c functionality to happen correctly, savegame3.c needs to be created almost immediately after branching 2.6 - before any 3.0-specific savegame functionality gets added (wrongly to savegame2.c)
