Fix get_remote_file_size() and rename it
Fix get_remote_file_size() and rename it

Used to return 0 always due to an assignment error.

This didn't matter much for http. But it's important for protocols
like file.

Renamed to remote_info_simple_file_size() to make it clear
when the function is called.
