PetscSF: Fix buffer displacements for 32bit integer builds
Use MPI_Aint to store displacements and prevent truncation.
This issue occurs for buffer sizes in bytes approaching the 2GB limit,

PetscSF: Fix buffer displacements for 32bit integer builds
Use MPI_Aint to store displacements and prevent truncation.
This issue occurs for buffer sizes in bytes approaching the 2GB limit,
`bufsize=n*unitbytes` with `n<=INT_MAX` but `n*unitbytes>INT_MAX`.

Update pack/unpack routines to do packing/unpacking for all neighbors in at most two routines
One is used to pack data in self to self communication; The second is used for remote communication.
So that on GPU, we can use at most two kernels to do packing/packing for all neighbors instead of multiple kernels

SF: Partially fix a bug when overlapped SF communications have same rootdata or leafdata on some ranks
Now we use two keys (rootdata, leafdata) to identify a pending communication. But that is still not
enough for cases where communications have same rootdata and leafdata on some ranks. Currently We
error out on these cases. See ex2.c for various cases we can handle and we can not handle.
