Add a block-structured distributed operator that presents itself to Krylov solvers and preconditioners as a single ordinary distributed matrix (the PSBLAS analogue of PETSc MATNEST), targeting saddle-point systems M = [[A, B^T], [B, 0]] with possibly rectangular sub-blocks. Library (base/modules): - psb_desc_nest_mod, psb_d_nest_mat_mod: grid of per-field descriptors and per-block sparse storage. - psb_d_nest_base_mat_mod: psb_d_nest_base_mat, the operator extending psb_d_base_sparse_mat (local csmv, free, field-split hooks for a future block preconditioner). - psb_cd_nest_tools_mod / psb_d_nest_tools_mod: composed global descriptor with union halo (psb_cd_nest_compose) and rectangular local block builder (psb_d_nest_rect_block), plus the per-block assembly wrappers. - psb_d_nest_builder_mod: psb_d_nest_matrix, the user frontend with the init/ins/asb/free pattern hiding all descriptor/halo/compose/setup boilerplate. - psb_d_nest_mod: umbrella module (use psb_d_nest_mod). Remove the earlier bespoke per-block prototype (comm/psblas/vect modules and the pde_nest_psblas test) superseded by the single MATNEST design. Tests (test/nested): glob (square operator vs monolithic CSR oracle), rect (genuinely rectangular blocks), cg (low-level path, ill-conditioned SPD red-black Laplacian solved with standard CG), builder (same solve via the utility), plus a README describing the design and usage. All pass serially and in parallel, with results invariant to the process count. Build hooks updated (autotools Makefiles + CMakeLists); the nested tests are relocated out of test/pdegen into test/nested. Author: Simone Staccone (Stack-1)
