It was previously stored at the end of the array of per-player flags and
set by calling SetLosRevealWholeMap with the player ID -1. However, ever
since the introduction of observer mode in 883f307b40, -1 is the player
ID of observers everywhere else including for GetLosRevealWhole:
GetLosRevealWhole(-1) always returns true in order to reveal the map to
observers, however, the cinema manager, for example, called it meaning
to find out whether the whole map is revealed to all players.
To fix this and avoid confusion about this in the future, this patch
splits this flag from the per-player flag array and introduces new
functions to set and retrieve it.
