Ipopt

- fixed bug in MA97 interface that lead to conversion issues
(by J. Hogg) [r2566, 260]

- fix a memory allocation in Java interface in cases where jint
has a different size than int [r2513]
- the buildsystem now tries the Accelerate framework instead of
vecLib for finding Blas/Lapack on MacOS X

- fix compilation issue of Java interface on systems where Index
and jint have different size [r2498, 241]
- work around failing check for random number generator with gcc
4.8.3 [r2495, r2496]
- readded IpTaggedObject.cpp to list of sources to compile in
MSVS v8-ifort project file [r2492]
- work around missing support for thread-local storage with gcc < 4.5
on MacOS X [r2491, 243]
- fix call to MKL Pardiso init function [r2489]
- speed up Triplet to CSR converter [r2487, 234]
- fixed a bug in equilibration scaling where average values were
computed incorrectly (by V. Zverovich) [r2483]

- fixed a bug, introduced with Ipopt 3.11.0, where the tag in the
Ipopt's caching mechanism was not unique over time, which lead
ot failures of Ipopt that were difficult to debug or recognize
(e.g., Ipopt may have stopped with an restoration failure for
instances that solved fine with Ipopt 3.10) [r2472, r2473]
I'm very thankful to Gabriel Hackebeil and Kurt Majewski for
their debugging effort on this issue.
- building Mumps with pthreads is now disabled by default [229]
- fixed setting of LD on Windows (now set to link only iff using
MS/Intel compilers) [230]
- fixed download link for Gnumex [r2471]
- for some messages about too-few-degrees-of-freedom and restoration
failure, the message level changed from error to strong-warning
[r2460, r2469]
- revised calls to MPI_Init and MPI_Finalize in Mumps interface [r2467]
(MPI_Init is now called only if function MPI_Initialized is available
and MPI has not been initialized already; MPI_Finalize is only called
if Ipopt also called MPI_Init; ...)

- adapted PARDISO parameters when using MKL PARDISO to be close
to using Basel PARDISO
- added options pardiso_max_iterative_refinement_steps and
pardiso_order; the former defaults to 1 in case of MKL PARDISO,
which may help on instances that otherwise fail due to numerical issues
- removed duplicate code in IpQualityFunctionMuOracle.cpp [225, r2445]
- fixed bug in triplet to csr converter [226, r2446]
- minor changes in buildsystem

- updates to Matlab Interface build system (by T. Kelman)
- fix to updates of R Interface [r2416, 223]
- fixed SHAREDLIBEXT in v8-ifort's config.h [r2426, 224]
- minor fixes to the buildsystem
