[Freeciv-Dev] [Patch] Remove goto_zoc_ok and dir_ok

[Raimar Falke <hawk@xxxxxxxxxxxxxxxxxxxxxxx>]

I claim that the attached patch will not change anything on the
behavior of the code. It turns out that goto_zoc_ok has never
worked. Studing goto_zoc_ok reveals that it returns 1 if the
can_step_taken_wrt_to_zoc is true and 0 otherwise.

Thue: you made these changes. Maybe you know something I missed or can
fix it.
