For proper alignment on the heap Eigen needs to have a custom
allocator. There are two forms, new and in-place new. To make sure
that memory is aligned using new, one needs to overload new by
adding EIGEN_MAKE_ALIGNED_OPERATOR_NEW to any struct which contains a
fixed size Eigen type either through inheritance or as a direct or
indirect member. For the in-place new one need to use the
Eigen::aligned_allocator (e.g. for std::vector, std::list,
FixedArray, etc.). For more details see:
https://eigen.tuxfamily.org/dox/group__DenseMatrixManipulation__Alignement.html
This CL adds EIGEN_MAKE_ALIGNED_OPERATOR_NEW to all structs, which
contain fixed-size Eigen types and uses the Eigen::aligned_allocator
for containers which stores structs of fixed-size Eigen types.

Skip the test in dynamic_sparsity_test when there are no sparse
linear algebra libraries available.
Also fix a minor typo in version_history.rst

The addition of crsb_rows and crsb_cols to CompressedRowSparseMatrix
broke the build for problems with dynamic sparsity.
The fix is to remove unnecessarily filling of row_blocks and col_blocks,
which was triggering a check inside CompressedRowSparseMatrix around
block handling, since block structure makes no sense for matrices with
dynamic sparsity anyways.
Also added a test "dynamic_sparsity_test" based on i
examples/ellipse_approximation.cc
Thanks to Richard Stebbing for reporting this.
