Ipopt

- allow for --without-matlab-home to disable check for Matlab [r2748]
- add dppsv to v8-ifort [r2746]
- disable error in LibraryHandler.c if snprintf detection failed [r2751]

- fill Mumps struct with zeros when allocating in Mumps interface [r2724]
- minor fix in build-system of ThirdParty/ASL

- fixed setting for parallel solve when using MKL Pardiso
(by t1393988511) [r2711]: parallel solve was disabled (which
is not the default); note, that the setting for parallel
factorization was not affected
- fixed invalid read in AMPL interface for problems without
objective function [r2715, 305]
- updated ThirdParty/ASL to retrieve updated ASL (20180528) [305]
- name JIpopt library libjipopt.dylib on Mac OS X [r2718, 275]

- fixed memory leak in MA86 interface (by mhahn) [r2700,283]
- fixed handling of time limit when reoptimizing: CPU time spend
was accumulated when reoptimizing, while it should have been
reset for each solve (by paul-scott) [r2702,r2703]
- fixed sign in Jacobian finite-difference approximation when point
was close to variable upper bounds (by Enrico Bertolazzi) [r2704]

- add define for FORTRAN_INTEGER_TYPE to config_ipopt_default.h
- IpoptApplication::RethrowNonIpoptException() now returns whether
non-ipopt exceptions were rethrown before the method was called.

- removed compiler flag -pedantic-errors to avoid problems with some
configure tests when using recent GCC versions
- fixed rare bug in handling variable/constraint names in AmplTNLP
(by G. Hackebeil) [r2673]
- the get.Mumps script in ThirdParty/Mumps now renames libseq/mpi.h
to libseq/mumps_mpi.h to avoid conflicts when building in a MPI
environment (by T. Ralphs); note that if updating an existing
checkout/download of Ipopt, you may have to rerun get.Mumps
