Merge branch 'wence/feature-patch-facets' of github.com:firedrakeproject/petsc into wence/feature-patch-facets

We now need to call MatAssemblyBegin/End on the patch side, as there's
more than one kind of assembly loop possible.

PATCH: Pass correct user context to facet operator

Do the same for the rsize > 3000 branch

Fix the sparsity pattern when interior facet integrals are present, for rsize < 3000

PATCH: Provide callbacks for interior facets

PCPATCH: Idiot^3

PCPATCH: Idiot^2

PCPATCH: Idiot

PATCH: More indexing fixes

PATCH: Fix incorrect indexing

PATCH: WIP getting towards patch interior facet assembly

PATCH: viewer options for facets

PATCH: WIP integration on facets of patches

Merge remote-tracking branch 'origin/hongzh/add-euclid-support'

Change 'Solver on patches' to 'KSP on patches' or 'SNES on patches'.

This circumvents needing to update the test output.

More speculative build fixes

Add Euclid support through hypre

Euclid is the suggested alternative to PILUT which is not supported by hypre
