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.
