Clean up PETSc str ops to use more secure implementations where possible. These include:

- Use PetscStrncpy()/PetscStrlcat()/PetscMemcpy() over PetscStrcpy()/PetscStrcat()
- Use PetscArraycpy() over PetscMemcpy() as appropriate for string buffer copying
- Use built in string from name over hardcoding
- Use sizeof over hardcoded length
- Replace some Strlcat with Strncpy when offset is known
