* Sets a stream to be uploaded by this channel.
*
* Most implementations of this interface require that the stream:
* (1) implement threadsafe addRef and release
* (2) implement nsIInputStream::readSegments
* (3) implement nsISeekableStream::seek
*
* History here is that we need to support both streams that already have
* headers (e.g., Content-Type and Content-Length) information prepended to
* the stream (by plugins) as well as clients (composer, uploading
* application) that want to upload data streams without any knowledge of
* protocol specifications. For this reason, we have a special meaning
* for the aContentType parameter (see below).
*
* @param aStream
* The stream to be uploaded by this channel.
* @param aContentType
* If aContentType is empty, the protocol will assume that no
* content headers are to be added to the uploaded stream and that
* any required headers are already encoded in the stream. In the
* case of HTTP, if this parameter is non-empty, then its value will
* replace any existing Content-Type header on the HTTP request.
* In the case of FTP and FILE, this parameter is ignored.
* @param aContentLength
* A value of -1 indicates that the length of the stream should be
* determined by calling the stream's |available| method.
