with apologies for not noticing this at the time instead of 15 months 
after the fact....  I object to this removal.  If you read the commit 
log from when the sources were imported it mentions having some critical 
bug fixes.  Since then, a few more bug fixes have been applied in the 
pcb tree.  Unfortunately the original sources were imported *after* the 
initial round of bug fixes which makes it harder to see what those were. 
  The other thing I will note is that GTS has not had an actual release 
in more than a decade and the bug fixes that were in the PCB source tree 
were more recent than that.  So.... while I generally agree that we 
should not include 3rd party library sources in our tree, this case 
probably warrants putting gts back.  If the concern is slow compilation 
time, we can disable if the topo router is disabled.

If/when the fixes that the topo router depended on are submitted back 
upstream and gts has a release incorporating these and that release has 
a chance to make it into at least some of the more popular packaging 
systems we can revisit.  However, right now, we can't count on any of 
the packaging systems having a gts which works correctly in pcb.

This change should be reverted.

Again, my apologies for being absent for the initial discussion on this.
