PCFIELDSPLIT should set options on the splits' KSPs only when necessary.

Hg-commit: 3c0d43fb59116e685988774ecf514b11ec27f5eb

Keep correct reference counts to splits' DMs in PCFIELDSPLIT.

Hg-commit: 188af97997792bbfe58dd8e5e4deef86500f0582

Backed out changeset 5a9ebf885615. Now PCFIELSPLIT Schur attaches A11's nullspace to S.

Hg-commit: 1723d4624521b3378f92ed1e7cc618e9fed1f549

Check for fieldsplit blocks' constant nullspace directly and avoid attaching A11's nullspace to S.

Now the inner A solve in S = C^T A^{-1} B by default is the same KSP as the (0,0) block. If you give any options with -fieldsplit_1_inner_* (or <split name>_inner_*) then it creates a new KSP with th

Now the inner A solve in S = C^T A^{-1} B by default is the same KSP as the (0,0) block. If you give any options with -fieldsplit_1_inner_* (or <split name>_inner_*) then it creates a new KSP with that prefix
- Added MatSchurComplementSetKSP()
