libceph: use void pointers in page vector functions
The functions used for working with ceph page vectors are defined with char pointers, but they're really intended to operate on untyped data. Change the types of these function parameters to (void *) to reflect this. (Note that the functions now assume void pointer arithmetic works like arithmetic on char pointers.)
