Commit d0d7545ec1 ("Unload robot movies on exit") intended to shorten
the lifetime of the loaded data, but failed to save the unique_ptr, so
the lifetime was shortened more than intended. Save the unique_ptr so
that the movies remain loaded.
Also, add a [[nodiscard]] annotation so that the compiler can warn if
this mistake is repeated.

Fixes: d0d7545ec1 ("Unload robot movies on exit")
Callers only ever test for whether the movie was skipped, and never
distinguish between a movie that ran to completion versus a movie that
the user interrupted. Combine these two statuses into one value, and
eliminate the logic in RunMovie that picked which of the two to return.
Rename symbol OGL to DXX_USE_OGL 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 -lzw OGL -- '*.h' '*.cpp' | xargs -0 sed -i -e 's/\(\s*#\s*if\)def\s*OGL/\1 DXX_USE_OGL/' -e 's/\(\s*#\s*if\)ndef OGL/\1 !DXX_USE_OGL/' -e 's/\(\s*#\s*if !\?\)defined(OGL)/\1DXX_USE_OGL/'
Rework movie loading to fix loading built-in robot movies. The previous
code always ignored loading the last entry in the movie array, which was
blank until 18f6919b33. The last entry
was unused after d38a3d1362, so it was
removed, which caused the code to skip the robots entry.
Commit d38a3d1362 broke unloading add-on
movies by removing the strcpy which saved their name. Add code to save
the name to extra_robot_movie_mission and call it when switching
missions.
