[Cbc] CBC feasibility pump

[John J Forrest]

Apologies for the link errors I introduced on Windows.  It should be OK
now.

The error arose because I have made cbc more flexible.  The standalone
version was often faster than the user's code so I have modified so user
can use the cbc solver as a function, passing arguments in either by
"argc,argv" or as a string in a similar way as in standalone solver.  There
is an example in Cbc/examples/driver3.cpp.

However some messages from the standalone solver were not going through
message handlers.  To fix this and test I had fixed it, I added test code
in CoinSolve.cpp which was only called on a #define.  However
MyMessageHandler was still defined - hence the error on Windows.

You should be able to build Cbc with Visual Studio 8 by doing the
following:

  1. svn checkout https://projects.coin-or.org/svn/Cbc/trunk coin-Cbc-trunk

  2. open the file coin-Cbc-trunk/Cbc/MSVisualStudio/v8/Cbc.sln with
     visual studio C++ express edition. You can probably do this
     by navigating to the file in Windows Explorer and double clicking
     on the file.

  3. From the menu bar select "Build" - "Batch Build", and then rebuild
     everything.

I tried these steps and unfortunately they did not work.
It seems that a code change made yesterday introduced a link time error.
I created a problem ticket for this.
See https://projects.coin-or.org/Cbc/ticket/26

If step 1. is changed to be
      svn checkout --revision {2007-07-30}
https://projects.coin-or.org/svn/Cbc/trunk coin-Cbc-trunk
then the code checked out should be before the introduction of the link
error.
