Resolve object replication for classes with 3rd party dependencies

[lkuchenb]

There are several issues with shogun classes that depend on 3rd party libraries, e.g. CMKL or CLibSVM. The named two currently don't have any of their members registered as parameters and for the non-shogun ones (LibSVM, CLPLEX, GLPK, ...) it has to be checked upstream how to implement this first.

• Check all shogun classes for Parameter registration. Test cases for clone() and equals() exist for CLibSVM etc, but are useless, since they always check out fine with no parameters!
• Check 3rd party dependencies and how to replicate their objects.

The member variables in LibSVM classes could actually be moved to the train_machine scope, so maybe there is not much to do there.

I prepared a patch for MKL in #3730

And a patch for LibSVM classes in #3731
