[Freeciv-Dev] (PR#12165) duplicate tileset tags cause a memory leak

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

This is in 2.0 and 2.0.99.

The code is in tilespec.c:

         for (k = 0; k < num_tags; k++) {
       (void) hash_replace(sprite_hash, mystrdup(tags[k]), ss);
         }
       }

this leads to lots of leaked memory from the mystrdup call, when civ3gfx 
(which has many duplicate tags) is used.

I imagine this is a problem anywhere where hash_replace is used!
