/**
 * Factory method to get an nsInputStream from a byte buffer.  Result will
 * implement nsIStringInputStream, nsITellableStream and nsISeekableStream.
 *
 * If aAssignment is NS_ASSIGNMENT_COPY, then the resulting stream holds a copy
 * of the given buffer (aStringToRead), and the caller is free to discard
 * aStringToRead after this function returns.
 *
 * If aAssignment is NS_ASSIGNMENT_DEPEND, then the resulting stream refers
 * directly to the given buffer (aStringToRead), so the caller must ensure that
 * the buffer remains valid for the lifetime of the stream object.  Use with
 * care!!
 *
 * If aAssignment is NS_ASSIGNMENT_ADOPT, then the resulting stream refers
 * directly to the given buffer (aStringToRead) and will free aStringToRead
 * once the stream is closed.
 *
 * If aLength is less than zero, then the length of aStringToRead will be
 * determined by scanning the buffer for the first null byte.
