James Bergstra 812376955a ENH: adding iter_limit to libsvm
This commit adds support for a new libsvm parameter, which permits setting a
hard limit on the while loop in the svm.cpp file, in the Solver::Solve
function. Without this functionality, it has been observed that libsvm hangs
without converging in a reasonable time -- it can take days instead of
seconds, and perhaps it is in fact an infinite loop, I don't know.  This
commit allows the user to set a hard limit on the number of libsvm iterations,
and modifies the libsvm bindings to raise a new exception of SolverTimeout
when this limit is reached.

Lars Buitinck 706319655a ENH refactor liblinear prediction code and add classes_ member
Liblinear bindings removed from LinearSVC and LogisticRegression
prediction code in favor of NumPy code.

* no more copying of X at predict time
* no more unchecked malloc at predict time
* -4000 lines of C code
* simpler handling of coef_ and intercept_

Also, support symbolic class names and classes_ on both estimators.
