The Intel Fortran compiler accepts the flag "-fopenmp" for compilation
with OpenMP. However, the Intel MPI compiler wrapper does not.
With the Intel compiler, this leads to the fact, that if ELPA is compiled
with the "-fopenmp" flag a not thread-save version of the Intel MPI
library is used and the test (with make check) fails.

Intel promised to solve this in the future.

However, for now the problem is solved in the user friendly way that no
manipulation of the MPI compiler wrappers have to be done:

For detecting the OpenMP compiler flags, instead of the predefined
macro "AC_OPENMP" of autoconf a modified macro "AX_ELPA_OPENMP"
is used, which first checks "-openmp" and only then "-fopenmp".
Thus it is ensured that the Intel compiler (and mpi compiler wrapper)
does not get confused.

This is invisible for users calling "configure" during the installation
process.

If the ELPA library is compiled with OpenMP, the tests check
whether the MPI library provides the neccessary threading
level.

There has been the error, that if the required threading level
was not available the test programs aborted, put no explicit
error code was set. This is changed now.

A few kernels could not be used together with OpenMP:
an interface error prohibited the compilation.

Removed a forgotten C-preprocessor error flag.
Futhermore, describe in the documentation why at the moment a
build of Bluegene P/Q kernels and OpenMP is not allowed.

Automake does normally not understand the dependencies of Fortran 90
modules, thus a parallel build will almost certainly fail.

As in ELPA 2011.12.002, the ELPA_development_version_qr  now
includes scripts from the fdep project (see git.schokokeks.org/fdep)
which cirumvents this problem.

Thanks to Lorenz Huedepohl, now a parallel build works.

Identical to ELPA 2013.11.001 the build procedure is updated

  - updated INSTALL documentation
  - improved description of kernels src/elpa2_kernels/README_elpa2_kernels.txt
  - improved OpenMP builds:
      * usage of OpenMP can now be specified with
        "--enable-openmp" or "--with-openmp"
  - improved checks for AVX build (identical to ELPA 2013.08.003):
     * if AVX kernels are specified AVX compilation is tested
     * the option "--with-avx-optimization" automatically updates
       CFLAGS and CXXFLAGS with optimization flags

The Fortran standard requires a maximum line length of 132 characters.
Linefeeds are introduced where necessary

Now, the branch ELPA_development_version_qr contains the full QR
functionality, which was introduced by Auckenthaler in the (obsolete)
ELPA_development_version_branch

Changes are:
- build procedure with configure like the other branches/releases
- renaming of a few files

The QR decomposition was tested for a few matrices and gave correct
results

- the files in the sub-dir src/elpa_qr from the ELPA_development_branch
  are introduced in the branch ELPA_development_version_qr

- the file tum_utils.f90 is renamed to qr_utils.f90

A developement version for MRRR algorithm is created;
Based on ELPA_development_version_OpenMP
