Rename rules.doc and rules.utils because GitLab treats the former as a MS Word document.

Add `MATDIAGONAL` and `PCMatSetApplyOperation()`
`MATDIAGONAL` (`MatCreateDiagonal()`) is an interface for
manipulating a diagonal matrix as a `Vec`, in particular supporting
no-copy modification of the diagonal and inverse diagonal via
`MatDiagonalGetDiagonal()`, `MatDiagonalRestoreDiagonal()`,
`MatDiagonalGetInverseDiagonal()`, and
`MatDiagonalRestoreInverseDiagonal`().
`PCMatSetApplyOperation()` and `PCMatGetApplyOperation()`
support using all the linear operators currently defined by a `Mat`
(`MatMult()`, `MatMultTranspose()`, `MatMultHermitianTranspose()`,
`MatSolve()`, `MatSolveTranspose()`) as the operation of `PCApply()`
for a `PCMAT`. The advantage over a `PCSHELL` is that the other
operations (`PCApplyTranspose()`, `PCMatApply()`) are automatically
inferred.
These tools help make it easier to route operations like
`VecPointwiseMult()` and `VecPointwiseDivide()` through
`KSPSolve()` to avoid handling diagonal matrices as a special
case (a pattern that is going to be removed from `MATLMVM`).
