Descent 1 has no headlight powerup. Code to read headlights was
incorrectly added in 357e1b0144, but no code was added to write
headlights, so the Descent 1 lighting code checked for headlights that
never existed. Guard the headlight global variables and the associated
logic with if(D2).
Fixes: 357e1b0144 ("Made lighting code work with actual RGB values and added feature to let certain objects emit colored dynamic light as well as let mine flash red when control center destroyed (OpenGL-only at the moment)")
Expose sphere_intersects_wall and call it directly from
boss_fits_in_seg, so that boss_fits_in_seg does not need to modify the
position and segment of the boss during the test.
If boss has teleported before, even before a loaded state was saved, play the boss looping sound immediately when loading the saved game (if near the boss). Resolves issue #326.
When objp is nullptr, ai_door_is_openable assumes Buddy_objnum is a
valid object number, but this assumption is not guaranteed to be true.
When it is false, the game crashes. This crash can be triggered by a
brain robot trying to make nearby robots snipe.
Fix the crash by passing the robot of interest.

Macro LINE_SPACING previously used global grd_curcanv implicitly.
Change it to take a canvas argument. Change all callers to pass
grd_curcanv, so that usage is explicit.
As a macro, it always refers to the global grd_curcanv. This interferes
with converting canvas handling to be an argument. Expand GWIDTH so
that uses of grd_curcanv can be changed individually.
Movement handling has an ugly hack that tries to grab powerups near the
console player, but it reuses general collision handling and fails to
check whether the player is alive.
Add a liveness check. Place the check so that it happens once, before
the objects are scanned, rather than being needlessly repeated for every
object.
Refactor the collision code to let the movement hack skip the parts it
does not need.

Kreator proposed restoring the Descent 2 cheat that grants homing
capability to all weapons. This commit implements that proposition,
with some changes to the implementation details.

Contains 2 calls - to obj_create and init_ai_object. For safety reasons and tidiness compared to using obj_create directly. The call to init_ai_object in recreate_thief was already redundant.
Use std::equal_range to find the upper and lower bounds in a single
binary search, rather than relying on a linear search to find the first
sought element.
In multi_do_frame(), replace call to window_close(Game_wind) with returning window_event_result::close whenever multi_quit_game is true. Only using this return value where multi_do_frame() is directly called by GameProcessFrame(). multi_quit_game will only be set back to 0 when a new multi game is started.
Closing a window within its handler is problematic - it can result in an unstable state.
Replace call to window_close(Game_wind) with returning window_event_result::close to game_handler. Applies to when there is a failure in net_udp_level_sync(). Closing a window within its handler is problematic - it can result in an unstable state.
Replace call to window_close(Game_wind) with returning window_event_result::close to game_handler. Applies to whenever newdemo_stop_playback() is called. Closing a window within its handler is problematic - it can result in an unstable state.
Replace calls to window_close(Game_wind) with returning window_event_result::close to game handler. Applies to when DoEndGame() is called, DoGameOver() is called, aborting in the kmatrix screen (multiplayer game) during AdvanceLevel() and playing one demo frame causes playback to stop in GameProcessFrame(). Closing a window within its handler is problematic - it can result in an unstable state.
Valgrind warns when writing uninitialized data to a file. The Descent
savegame format requires writing certain fields that are no longer used.
Set those fields to 0 to prevent leaking stack data into the file.
init_player_stats_new_ship used select_primary_weapon and
select_secondary_weapon to assign the player's weapons. However, those
functions read the current weapon and jumped according to its value. A
new ship has no defined value for current weapons, so the jump triggered
an uninitialized value warning from Valgrind.
Add new functions set_primary_weapon, set_secondary_weapon that work
like the previous select_* functions, but always take the path used
for weapons not equal, without checking. This prevents the warnings
from Valgrind, as well as a theoretical risk of initializing the ship
improperly.
The declaration of valptridx_specialized_types needed to be found by
Argument Dependent Lookup, but this was inconvenient for some types.
Split the declaration of valptridx_specialized_types out from the
definition of valptridx global subtype.
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.
It was a convenient transition macro, but its presence was always
intended to be temporary. Expand it to ease the conversion of usage
sites that already have access to local player data through a local
variable.
