Log message:
libsvm: Update to 3.24

3.24: 2019/9/11
      fix compiling issues in matlab/Makefile: use mex only rather than build \ 
some .o files separately
      python interface:
            use array for reading data in python/commonutil.py to lower the \ 
memory usage
            fix a bug in python/commonutil.py for reading pre-computed kernel
      minor improvements and bug fixes

3.23: 2018/7/15
      add more digits of predicted file, model file, scaled data and data from \ 
matlab libsvmwrite: to %.17g
      revise svm-scale.c so features in test data that do not appear in training \ 
data are scaled to zero.
      remove unnecessary tab or space in all files
      python interface:
            add Scipy support
	    add scaling (csr_find_scale_param and csr_scale functions)
	    put some utility functions identical in LIBLINEAR to commonutil.py.
	    functions for scaling are put in commonutil.py.
	    sort column indices of csr matrix before training as feature indices must \ 
be ascending
      convert Qt version of svm-toy from Qt4 to Qt5
      remove gtk svm-toy because we stop maintaining this tool
      minor improvement of descriptions in README

3.22: 2016/12/22
      probability output:
             if 2 classes, directly output the predited probabilities
	     rather than run the iterative algorithms for multi-class situations

3.21: 2015/12/14
      pre-built windows exe files changed from 32 to 64 bit
      matlab interface:
             now use #include "../svm.h"
             fix some minor issues in make.m of matlab interface
