* Build the read-ahead mechanism into SftpFileStream
This change unifies the SFTP download implementations that exist via DownloadFile and
via SftpFileStream, by rewriting SftpFileStream to perform the same "read-aheads" as
DownloadFile. This brings the performance of downloads via SftpFileStream in line with
DownloadFile, such that the latter is now effectively SftpFileStream.CopyTo. It also
brings the recently added DownloadFileAsync up to speed since that was implemented via
SftpFileStream.CopyToAsync.
The methodology is a mix of the previous one and that within OpenSSH: the first call to
SftpFileStream.Read sends one read request to the server. The second sends two and when
not interrupted by Write or similar, the number of in-flight read requests continues to
scale up in this fashion.
I have measured CopyTo to be 3-20x faster than before, depending on file size and server
round-trip time.
