(svn r12252) -Fix [FS#1801]: Broken FollowTrack_t related functions (thanks michi_cc).

 -Fixed by removing FollowTrack_t structure and all related functions. Their purpose was to allow to call track followers from C code. They were:
  1. never used
  2. obsoleted by switching to C++

-/** Track followers. They should help whenever any new code will need to walk through
- * tracks, road or water tiles (pathfinders, signal controllers, vehicle controllers).
- * It is an attempt to introduce API that should simplify tasks listed above.
- * If you will need to use it:
- *   1. allocate/declare FollowTrack_t structure;
- *   2. call FollowTrackInit() and provide vehicle (if relevant)
- *   3. call one of 6 FollowTrackXxxx() APIs below
- *   4. check return value (if true then continue else stop)
- *   5. look at FollowTrack_t structure for the result
- *   6. optionally repeat steps 3..5
- *   7. in case of troubles contact KUDr
