Merge branch 'stefanozampini/fix-matmatmult-prj' into 'maint'

Fix MatMatMult old API when reusing dense output matrix

See merge request petsc/petsc!2761

MatSetSeqAIJWithArrays: rework the internal routine

Set type only if passed or if the already used matrix is not derived from AIJ
Skip MatAssemblyBegin/End

MatMatMult drivers: use single internal driver

clear product if user used a DENSE matrix and MAT_REUSE_MATRIX and matrix has no product stored

MatMatMult: fix MAT_REUSE_MATRIX case with already allocated dense result

This branch reorganizes the API of mat-mat operations: A*B, At*B, A*Bt, PtAP, RARt, A*B*C
- See matproduct.c for detailed description of new API
- removed API function XXXSymbolic() and XXXNumeric()
- removed subroutines MatMatMult_xxx, MatPtAP_xxx, ...
- modified MatxxxSymbolic_XXX() prototype (product is an input now)
- selection of algorithm is in MatProductSetFromOptions_xxx()

Promote examples/{tests,tutorials}/ to {tests,tutorials}/

This shortens paths and improves consistency between test target names
and paths to the source and output files. Most of the work was
completed by this script, followed by mild cleanup of nonconforming
cases.
