657d9143d1 SSH_LOG_DEBUG: Recategorize loglevels
Loglevel INFO is the default openssh configuration setting which does not print
redundant information. On a system using openssh with loglevels set by the
terms of openssh will cause unwanted log lines in the output.
recategorized based on - SSH_LOG_DEBUG are informational debug logs (no error)

1ff6dda616 Correctly parse v4 subsecond timestamps
All subsecond timestamps are only in the packets if both the
SUBSECOND_TIMES flag and the timestamp flag, e.g. ATTR_ACCESSTIME
are set.

SUBSECOND_TIMES are not very common across server implementations
(e.g. openssh does not include it, nor does libssh's sftpserver
implementation), but this interpretation of the SFTP protocol draft
is used by WinSCP and lftp.

Fixes T219.
