Use uint32_t for all packed object counts.

As we permit up to 2^32-1 objects in a single packfile we cannot
use a signed int to represent the object offset within a packfile,
after 2^31-1 objects we will start seeing negative indexes and
error out or compute bad addresses within the mmap'd index.

This is a minor cleanup that does not introduce any significant
logic changes.  It is roach free.
