Move function call to a new line

Hg-commit: 2cc1728cf4556bf0c65dcf009ba312641b71d988

added -1 to sizes for VecScatterCreateLocal() so it won't check against vector sizes when scattering.

Hg-commit: dfbb86e540c7927c2d80eb17a3372c9c7779b49e

added more pthread vector functions
added a pthread matrix function (not yet operational)

Hg-commit: 402caddad6a4ab372111fbc5baac892290efd412

Const argument for VecStrideScaleAll

Hg-commit: f46ad0d2c312c43654f1f55c2fc13d895eb36746

C89 does not have VLAs

Hg-commit: 7c2bb21ffd4231e77141fef9b3774aeb58cca7e7

add an example of "Taking part of existing array to create a new vector" [petsc-maint #76989]

Hg-commit: ad3bca521c6426cb4cc2a74443e3f04d1ad497b8

actually handle DMSetVI() only if there are active constraints and hence the Jacobian has rows and columns removed

Hg-commit: 5bb2d33275b9a0a03992d4c5a94d9fffcb56b550

Add ISLocalToGlobalMappingConcatenate() and use it from DMCreateLocalToGlobalMapping_Composite()

Hg-commit: 66da97843ce512d460b2bed1ca80d60e31ae2944

VecGetSubVector_Nest: error if an unknown sub-vector is requested

Hg-commit: 5c422b1a40382b75d93507415b902bafa7df2462

Remove overloaded functions for now

Hg-commit: fac17f26a6367952b824a028a8c2a9fa08e4e6a0

More PetscSection interface, Section copy is broken
- Overloaded functions for PetscUniformSection
- Work on example for Section parallelism

Hg-commit: eefeb0516a2309f327c5775d4bf8eef6506a7ca1

Start casting floating point literals to (PetscScalar) to work with std::complex<float>

There is still much more to be done.

Hg-commit: 71e5798007d37fa1f814512de7878a7dadae5358

saved version that works using -use_thread_pool

Hg-commit: 823456f984d21b7f8bb09c653819097c2d6927fc

some work on work threads for PETSc, not yet working

Hg-commit: 6232f30f11ef9a985f9e4aa9d087fe565860d08f

fixes that came up in buildung cuda stuff

Hg-commit: 0d15701e97c548d2383326121c6e93db7179a502

ex12 now works in one case, but relies on a hack
- ex12 will not work in general because global Vecs do not store boundary values
- Initialize PetscSection correctly
- Small fix to L2G mapping

Forgot to add in last checkin

Hg-commit: 8c214043dea01c5020afcac631c06210b58118b8

moved localtoglobal mapping bmapping of matrices and vectors into the PetscLayout object

Hg-commit: 9101686a27a1dc39bda221d0212c5e4e16e2b091

all VecDuplicate_XXX except for VecDuplicate_Nested() reuse the reference to the parents PetscLayout instead of copying it
