Fix bug in PetscViewerBinaryWriteReadAll() that

Fix bug in PetscViewerBinaryWriteReadAll() that

prevented saving dense matrices whose number of entries on MPI rank 0 is greater than PETSC_MPI_INT_MAX by
removing unneeded PetscCall(PetscMPIIntCast(count, &cnt)); on rank 0.

Also removed unneeded potentially large malloc when used with on one MPI rank

Reported-by: Sreeram R Venkat <srvenkat@utexas.edu>

Code still does not work if any MPI process besides rank 0 has a matrix with a number of entries greater than PETSC_MPI_INT_MAX

PetscOptionsCreateViewer: add support for DAOS

See merge request petsc/petsc!7723

PetscOptionsCreateViewer: add support for DAOS

DAOS filenames have the form "daos:/path/to/file.h5". The prefix is
handled specially by the filesystem, thus needs to be part of the
filename.

Add shared memory support for PCMPI using both shmget() and MPI_Win_allocate_shared()

The use case of PetscOptionsGetViewer() has evolved to no longer be the get/restore model

Hence the code needs to be refactored

Introduce PetscCallNull() and PetscCallMPINull() to simplify PETSC_VI

This requires some changes to user FORTRAN code

Pass PETSC_NULL_XXX_ARRAY when passing a NULL as an argument that is expecting an array
Pass PETSC_NULL_ENUM when argument returns an enum instead of PETSC_NULL_INTEGER
Pass arrays (and not scalar values) when the argument is expecting an array; this means replace, for example, the argument v with [v]
Use PetscObjectIsNull(obj) to check if the object is NULL, instead of obj == PETSC_NULL_XXX

The compiler will now automatically prevent you from using the wrong argument type for the first three bullets above
This will also require an update sowing with the new sowing branch this MR is using.
