s3: Differentiate between posix files with colons and actual streams
It is possible for a posix file created locally or over nfs to have a ":" in the name. Since ":" is a reserved character in windows, filenames containing a colon must be mangled in a directory listing. Right now files containing colons will not even be displayed in directory listings if streams modules are in use. During the directory listing the file will be detected as a stream because of the colon, but the streams module will fail to find the stream since it doesn't exist. This fix adds a step to is_ntfs_stream_name that stats the filename to differentiate between actual streams and files containing colons. While this is an improvement, it isn't perfect. Consider the case where there is a file on disk called "a.txt:s1" and also a file called "a.txt" that has a stream called "s1". This patch will always preference "a.txt:s1" over a.txt's s1 stream. The real issue is that at the vfs level, the vfs modules have no way to tell between a demangled name with a colon and an actual stream. A more invasive, but better, long-term fix would be to add all paths that come over the wire into a struct containing metadata about the path. This metadata could include a flag to indicate whether the path came over the wire with a colon ":" (guaranteeing that the client is requesting a stream). Passing this struct down to the lower levels, including all path-based vfs calls, would allow the above case to be handled correctly in all cases.
