Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/480

RFC 7230 states: "Each header field consists of a case-insensitive field name followed by a colon (":")"

If the HTTP header coming back from the S3 server has 'content-length:' in it instead of 'Content-Length:' then s3fs fails to find the size and reports the file has 0 length.

I believe the problem code is src/s3fs_util.cpp line 721, where a case-sensitive find is performed.
