mpd/src/inputStream.h
Max Kellermann 82ca4cf8ce added InputStream.ready
The flag "ready" indicates whether the input stream is ready and it
has parsed all meta data.  Previously, it was impossible for
decodeStart() to see the content type of HTTP input streams, because
at that time, the HTTP response wasn't parsed yet.
