move eigen values related stuff of the QR module to a new EigenSolver module.
...
- perhaps we can find a better name ?
- note that the QR module still includes the EigenSolver module for compatibility

big reorganization in JacobiSVD:
...
- R-SVD preconditioning now done with meta selectors to avoid compiling useless code
- SVD options now honored, with options to hint "at least as many rows as cols" etc...
- fix compilation in bad cases (rectangular and fixed-size)
- the check for termination is now done on the fly, no more goto (should have done that earlier!)

JacobiSVD: implement general R-SVD using full-pivoting QR, so we now support any rectangular matrix size by reducing to the smaller of the two dimensions (which is also an optimization)
