Modify complex CBLAS functions to take void pointers instead of float or double arguments (to bring the prototypes in line with netlib and other implementations' cblas.h)

Fix cols/rows mixup in omatcopy 2nd step for BlasTrans cases

Equivalent of #1244 (issue #899) for the non-complex cases. Fixes #1289

Optimized standard Blas Level-1,2 (excluding nrm2 functions) for z13 (double precision). Issue 884

Use in-place transform shortcut only if matrix is square

This is MicMuc's patch from #899

* fix unlikely memleak in zimatcopy interface

* fix only unlikely memleak in zimatcopy interface

* fix only unlikely memleak in zimatcopy interface

* Hopefully, because this was found by error and trial (dark magic)
* Ref #786

added experimental support for optimized lapack fortran functions

If OpenBLAS is built using add_subdirectory(OpenBlas) as part of another project
then the paths set by CMAKE_XXX_DIR are relative to the parent project
and not the OpenBLAS project.

* Close #873

* Use stack allocation
* Disable multi-threading
* Ref #727

For better performance with small matrices
Ref #727

...not a matrix size. For GEMM_MULTITHREAD_THRESHOLD=4
(the default value) this does not change anything but
for other values it make the GEMM and GEMV thresholds
changing in the same way.

Close #742

The ones given in 3ae30cd was by far to low because I
mixed m and m*n in my measures. Note that the new ones
are closed to the [z]gemv ones which is comforting
that both are right.

Close #731

Ref #731

Ref #727

Close #722

Thank matzeri's patch.

The Ximatcopy functions create a copy of the input matrix
although they seem to work inplace. The new routines
XIMATCOPY_K_YY perform the operations inplace if the leading
dimension does not change.

Disable CBLAS and LAPACK.
