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.
Fixes bug where in the editor, you insert a robot with normal behaviour then play the level - it fails the check on the hide_segment index in init_ai_objects(). This is because hide_segment was written as the poisoned value of 0xfdfd if the behaviour of the robot is AIB_NORMAL - because hide_segment wasn't initialised. Therefore, always setting hide_segment to suppress this exception (it's an inexpensive operation seldom called).
Whenever a robot is sent to peers, it needs to be added to the local
mapping also. Move the one use so far into multi_send_boss_create_robot
to simplify maintenance.
gcc generates better code for:
if (variable == magic_constant)
return magic_constant;
than it does for:
if (variable == magic_constant)
return variable;
even though the two have the same result. Switch to the form which
generates slightly better code.
Mako88 reports that 2a19da88d4 changed
robot movement. That commit reordered the operations in a way that
tends to truncate small values prematurely. Restore the original order
of operations.

Fixes: 2a19da88d4 ("Pass object_base &to move_towards_vector")
Saved games dump robot ai_local state for all objects, regardless of
whether the object is a robot. Loading a game restored all ai_local
values, regardless of whether the object was a robot on restore. This
caused memory corruption in objects that were not robots when the
`ctype.`_T_ for that object was large enough to overlap
`ctype.ai_info.ail`.
Fix this by loading the ai_local into a junk buffer when the object is
not a robot. It would be better to skip over the bogus ai_local
entirely, but the structure of ai_local_read_swap makes that difficult.
Use the easy fix for now.
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.
