5770fa74f0 ai_helper: check variable type when viewing_side is required parameter 
This is done because the code will not complain but silently produce
non-sensical results if, for example, the filter is passed as the first
argument to get_visible_units().

1a5e9051a8 ai_helper: correctly and consistently deal with invisible units 
Previously, some functions saw invisible units, while others did not.
Moreover, this behavior could be triggered on and off for some
functions, but not for others, and the parameter to do so was not the
same in all cases.

Now, the default setting for all ai_helper functions is to ignore
invisible units and this can be turned on and off with the same
parameter, viewing_side, with the same syntax and meaning as for the
built-in functions wesnoth.find_path() and wesnoth.find_reach(). This
means hat it can be passed directly between those functions and all the
ai_helper functions.

e38dd8ff16 ai_helper: new utility functions to find attackable enemies 
Attackable enemies are defined as visible (can’t attack it if I can’t
see it) and not petrified.

This is in preparation for making the Micro AIs deal correctly with
hidden and petrified enemies.

faeaf5e47c ai_helper.get_attacks: improve check for units in the way 
Check whether the unit in the way has an unoccupied hex to move to.
Previously, it was only checked whether its reach was >1, which
sometimes can include only hexes occupied by units on its own side,
making the actual move impossible.

f6cdd85182 AI helper functions: code cleanup, first pass 
These function libraries are still work in progress and change
frequently, so the code cleanup is mostly just to make sure the syntax
is consistent with that used in the Micro AIs.  Changes or improvements
to the algorithms might be made at a later time.
