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

Browse Source 
-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
