Add longname field in sftp version 3
Add longname field in sftp version 3

Include longname field in SSH_FXP_NAME response in sftp version 3.
The longname field is an expanded format for the file name.
Although its format is unspecified by sftp protocol, some clients retrieve this field to
display file information.
According to documentation (https://tools.ietf.org/html/draft-ietf-secsh-filexfer-02)
the recommended format for the longname field is as follows:
-rwxr-xr-x   1 mjos     staff      348911 Mar 25 14:29 t-filexfer
(similar to what is returned by "ls -l" on Unix systems).
