leaks in multiple calls for preallocating AIJ matrices

[Barry Smith]

  Lisandro,

    I agree we should support multiple calls (or at worst generate an
error on the second call). Presumably the specific 
MatXXXYYYSetPreallocation() routines would simply free up their
current points and then (as it does now) allocate the appropriate new
space. Feel free to add this.
