Commit Message

Fixed ImapStream.Flush() to always flush the underlying stream when needed

ImapStream.Write() can drain its output buffer directly to the underlying
stream (when the buffer fills up or when writing block-sized chunks),
leaving outputIndex at 0. Flush() would then early-return without ever
calling Stream.Flush().

This was harmless while the underlying stream transmitted every write
immediately, but it is a latent deadlock for any underlying stream that
does buffering of its own. Track a 'dirty' flag so that Flush() knows
that bytes have been handed off to the underlying stream and that it
still needs to be flushed.
