[Freeciv-Dev] (PR#9856) RFC: caravans advisor

["Benoit Hudson" <bh@xxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=9856 >

Here's a tarball that includes two files and a really incredibly nasty patch 
for testing.  
  cd freeciv
  gtar xzvf caravan_optimizer.tgz
  patch -p0 < caravan_make.diff
for testing only:
  patch -p0 < caravan_hack.diff

When running, send signal USR2 to the civclient.  It will read
~/fc_caravan_param (an example is in the tarball) to determine 
what parameter to use, and optimize based on that parameter 
and the current unit in focus (which is ostensibly a caravan, but
I don't check that).

In the current code, the convert_trade option is unimplemented, 
so don't use it (I assert against it).

There's a warning that comes out: seems that most of the struct 
unit * arguments throughout the code are not constified even when 
they should be.  Should I remove my holy constness, or should we 
live with a warning until everything else gets constified, or do we hate 
const?

As per #9901, I can't really test on a recent CVS.  The patches apply, 
so how could it go wrong?
