This reverts commit 3c20c24ac0.
Rebirth no longer contains the Descent memory manager, but Rebirth still
has many traces of the paging support used in the DOS version. One of
the unfortunate and subtle traces of this support is that it allocates a
contiguous buffer for game data and loads many of the games bitmaps into
that buffer. The buffer is large enough for most workloads, but not
all. When the buffer is too small, it is discarded by
piggy_bitmap_page_out_all and rebuilt piecemeal to contain only what it
needs. Fixing this would be nice, but the memory ownership rules are
messy. The performance consequences of the legacy approach are not
sufficient to justify the effort to fix this properly. Instead, revert
to the legacy design.
To recognize getaddrinfo as supported, require that the AI_* flags
passed to it be usable:
- AI_NUMERICSERV must be defined as a number or be undefined
- If ipv6=1, then AI_V4MAPPED and AI_ALL must be defined as numbers
When getaddrinfo is used, raise _WIN32_WINNT from 0x501 to 0x600.
Otherwise, lower it to 0x500.
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.
Move the main part of obj_link into obj_link_unchecked. Implement
obj_link as sanity check assertions followed by a call to
obj_link_unchecked. Remove caller-side writes that were present solely
to bypass the assertions, since the assertions can now be bypassed by
calling obj_link_unchecked directly.
The segiter code used objptridx because end is signalled by object_none,
and vobjptridx does not allow object_none. However, the compiler
produces better code if segment_object_range_t returns vobjptridx and
future cleanups are easier if iterating objects_in yields vobjptridx
objects. Add a special-case override of the normal checking rules, move
the required checks into segiter, and then let segiter break the rules
normally enforced by valptridx. Add a comment explaining that this
permits unsafe coding and should be done only with a clear understanding
of the responsibilities it brings.
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.
Make the listbox handlers and all sub-handlers (when_selected callbacks) return a window_event_result. Makes code more readable and removes one use of window_close, making it easier to inform event system if a window closes in future.
The only caller for get_multi_endlevel_poll1 was DoEndLevelScoreGlitz,
which only called it on an unreachable path. That path is now gone, so
remove get_multi_endlevel_poll1.
