Changes 4.32:

The following new features were included in the MIP solver
*  MIP presolver
*  mixed cover cut generator
*  clique cut generator
*  Euclidean reduction of the objective value

Due to changes the routine glp_intopt may additionally return
GLP_ENOPFS, GLP_ENODFS, and GLP_EMIPGAP.

The API routines lpx_integer are lpx_intopt are deprecated,
since they are completely superseded by glp_intopt.

The following new branch-and-cut API routines were added:
glp_ios_row_attr      determine additional row attributes
glp_ios_pool_size     determine current size of the cut pool
glp_ios_add_row       add constraint to the cut pool
glp_ios_del_row       delete constraint from the cut pool
glp_ios_clear_pool    delete all constraints from the cut pool
