The module is intended to be hidden, thus I moved it into the public part of the legacy API. Some test programs use it, thus the test programs have now also access to ELPA's private modules. This is of course anyway necessary to test ELPA internals that are not exposed via the public API.

The functions in elpa_utilities are considered "ELPA internal", i.e. the should not be accessible by the users and thus not be part of the API.

Should be done in a more systematic way. In this case, in certain configuration 1stage_analytic test pased, while 2stage_analytic tests failed due to error larger then tolerance

Introducing new test in which matrix and its eigendecomposition is known and thus can be easily created and checked directly, without the need to use scalapack or any other communication (apart from reducing error). The test is based on the fact, that if L_A and S_A are eigenvalues and eigenvectors of matrix A, respectively, and L_B and S_B eigenvalues and eigenvectors of B, then kron(L_A, L_B) and kron (S_A, S_B) are eigenvalues and eigenvectors of kron(A, B). Since it is easy to know exact eigendecomposition of a small matrix (e.g. 2x2), and kron operator has very simple structure, we can construct arbitrarily large matrix and its eigendecomposition. We only have to select small matrices such that the resulting matrix has unique and ordered eigenvalues, so that the checking of the result is than easy. Each element of matrix, eigenvector matrix and eigenvalue vector can be quickly computed independently, just using its global coordinates. The test is currently limited to matrices of size 2^n, but by storing eigendecompositions of more small matrices (e.g. 3x3 and 5x5) we could construct any matrix of size 2^n*3^m*5^o, which would probably be sufficient, since most often used sizes (150, 1000, 5000, 2000, 60000) are of this form.

The routines "eigenvalues" and "solve_tridiagonal" are now also tested directly with the new API (and not only via the legacy API -> new API mapping) Todo: adapt test generator script to contain some logic

PGI has problems with elpa_int_value_to_string() where we return a variable-length string pointer. A workaround for now is to copy the string into a non-pointer variable of the same length. This closes issue #55
