[Ipopt] Ipopt release 3.11.4

[Stefan Vigerske]

Hi,

I just created a new Ipopt maintenance release.

Here is a list of changes (r1234 stands for a related svn changeset, 
#123 for a ticket number in the trac bugtracking system):

- hopefully fixed non-working linear solver loader in DLLs build with
   MSVS/v8-ifort project files [r2365]
- allow MC19 to be loaded via linear solver loader (by J. Currie)
   [r2366]
- fixed new point flag when running dependendency detector [r2368]
- experimental: adapted Pardiso interface to work with MKL Pardiso
   (by J. Currie, T. Kelman) [r2369, #216]:
   - in a few tests it has been found that Pardiso from Intel MKL
     nowadays seems to work fine with Ipopt
   - to use Intel MKL with Ipopt 3.11, one has to specify the MKL libs
     by --with-pardiso and add -DHAVE_PARDISO_MKL -DHAVE_PARDISO_PARALLEL
     to the compiler flags
   - as this is still an experimental feature, a Pardiso from MKL is not
     enabled by default (maybe it will be with 3.12)
- updated Ipopt/R interface to version 0.8.4 [r2373]
   - additional variables have been included in the object returned from
     ipoptr:
     z_L : final values for the lower bound multipliers
     z_U : final values for the upper bound multipliers
     constraints : final values for the constraints
     lambda : final values for the Lagrange multipliers
   - removed ipoptr_environment as argument in ipoptr (see also r2372)
- fixed bug in penalty term for centrality in quality function (not
   used by default) [#219, r2374]
- minor bugfixes in AMPL interface, debug print statements, and
   compound matrix (by G. Hackebeil) [#218, r2371, r2377,r2378,r2379]
- download scripts for ASL, Blas, and Lapack now first try to download
   tarball copies from the COIN-OR server

The source tarballs should be available tomorrow.

Enjoy,
Stefan
