endlevel wants to freeze the console player's last in-mine position.
Instead of copying the position out and back, refactor the flow to let
endlevel skip the update of the position.
This removes the need to walk all objects when creating a new one, since
each object can have a private generation counter, unaware of other
objects. For compatibility with demos, mix in the object's index when
writing the signature value.
Remove use of object_guidebot_cannot_reach and instead track the
reachability of the object as a separate flag. This allows the game to
remember when an object was found, but unreachable. Previously, it
would store only that some unreachable object was found. Now, it stores
the index of the unreachable object. This extra information is not used
yet.

Fixes: c3cead4319 ("Move Escort_goal_index to d_unique_buddy_state")
- Raise the player limit to 8.
- Remove the logic that forces player counts up/down when switching
between cooperative and deathmatch game modes.
- Add heuristics to add start positions for the extra players, since
standard maps will not have the required number of starts.
Packed structures cannot be passed by reference, may fail on
alignment-strict architectures, and are bad for performance even on
alignment-tolerant architectures. Using them for anything other than an
abstract layout declaration is a mistake. Remove
__attribute__((packed)).
Previously, valptridx used PREFIX for allow-invalid+mutable, c#PREFIX
for allow-invalid+const, v#PREFIX for require-valid+mutable, vc#PREFIX
for require-valid+const. Convert the types, factories, and all usage
sites to specify a qualifier for all four combinations:
im#PREFIX -> allow-invalid+mutable
ic#PREFIX -> allow-invalid+const
vm#PREFIX -> require-valid+mutable
vc#PREFIX -> require-valid+const
Changes to common/include/valptridx.h and common/include/fwd-valptridx.h
are manual. All other changes are generated by:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\(v\?\)\(\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/\1m\2/g'
for the 'm' prefix and:
git grep -lz -e '\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\>' | xargs -0 sed -i -e 's/\<\([cm]\(obj\|seg\|clwall\|wall\|actdoor\|trg\)\(ptridx\|ptr\|idx\)\(_t\)\?\)\>/i&/g'
for the 'i' prefix.
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.
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.
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.
