[freeciv-ai] bodyguard cleanup part#1+2, v3

["Per I. Mathisen" <per@xxxxxxxxxxx>]

I found that I could add even more to this part of the patch without
causing autogame differences, so I did. Here is the result. Only two very
notable expections to ai_unit_new_role() crusade remain, and they need
some consideration before being changed (preferably deleted), these are
the lines that set each unit to AIUNIT_IDLE each turn.

I've combined part 1 and 2 into one patch for simplicity.

Yours
