Windows: Fix ntohl() related warnings about printf formatting

On Windows, ntohl() returns unsigned long.  On Unix it returns
uint32_t.  This makes choosing a suitable printf format string
hard.

This commit introduces a mingw specific helper function
git_ntohl() that casts to unsigned int before returning.  This
makes gcc's printf format check happy.  It should be safe because
we expect ntohl to use 32-bit numbers.
