ewah: adjust callers of ewah_read_mmap()
The return value of ewah_read_mmap() is now an ssize_t, since we could (in theory) process up to 32GB of data. This would never happen in practice, but a corrupt or malicious .bitmap or index file could convince us to do so. Let's make sure that we don't stuff the value into an int, which would cause us to incorrectly move our pointer forward. We'd always move too little, since negative values are used for reporting errors. So the worst case is just that we end up reporting a corrupt file, not an out-of-bounds read.
