clang becomes confused trying to determine which vm_distance_squared
constructor to use for a literal input of 0x7fffffffffffffff, even
though the size of the input requires it to be `long` and only one
constructor can take a `long`. Switch from an explicit
0x7fffffffffffffff to the symbolic constant INT64_MAX, which has the
same value, but a platform-appropriate suffix to force the compiler to
pick the right type.
For general clarity, switch some other instances of integer maximum
literals to symbolic constants of the same value.
This commit has no effect on the generated code (except for changes to
line numbers).

Fixes: 17208cca79 ("Disallow int for vm_distance_squared")
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.

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.
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.

Rename symbol EDITOR to DXX_USE_EDITOR to show that it is a DXX
symbol, not one inherited from a library. Move it to dxxsconf.h to
shorten the command line.
This is a mostly automated transform, but the changes to SConstruct were
manual.
git grep -wl EDITOR -- '*.h' '*.cpp' | xargs sed -i -e 's/^\s*#ifdef \(EDITOR\)\>/#if DXX_USE_\1/' -e 's/\s*#\(el\)\?if \(.*\)defined(\(EDITOR\))/#\1if \2DXX_USE_\3/' -e 's/^\s*#ifndef \(EDITOR\)\>/#if !DXX_USE_\1/'

Caller collide_two_objects swaps the inputs to ensure A.type <= B.type.
OBJ_ROBOT = 2, OBJ_CNTRLCEN = 9, so A will always be the robot and B
will always be the controlcen. Rename the parameters accordingly. Add
assert statements to check this.
