This was requested by a user in early 2018. However, the proposed
prototype was susceptible to various forms of desynchronization, and was
unsuitable for merging. No further revisions were proposed, and the
feature languished. This commit enables the guidebot in cooperative
games and addresses the known synchronization problems, as well as some
other bugs that were uncovered during light testing. This is classified
as an experimental feature because it has not been heavily tested in
complicated games.

User roncli reports[1] an original game bug that prevents boss
teleportation from operating correctly if the program is not restarted
between each campaign. This is another case of a global variable being
used improperly. Reset the relevant variables when the boss is
initialized.

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.
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.

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/'
