Add two new options for the SFTP/SCP/FILE protocols: CURLOPT_NEW_FILE_PERMS

Browse Source 
and CURLOPT_NEW_DIRECTORY_PERMS.  These control the premissions for files
and directories created on the remote server.  CURLOPT_NEW_FILE_PERMS
defaults to 0644 and CURLOPT_NEW_DIRECTORY_PERMS defaults to 0755

data to itself. This enables several curl handles to share data. If the curl
handles are used simultaneously, you \fBMUST\fP use the locking methods in the
share handle. See \fIcurl_share_setopt(3)\fP for details.
.IP CURLOPT_NEW_FILE_PERMS
Pass a long as a parameter, containing the value of the permissions that will
be assigned to newly created files on the remote server. The default value is
\fI0644\fP, but any valid value can be used. The only protocols that can use
this are \fIsftp://\fP, \fIscp://\fP and \fIfile://\fP. (Added in 7.16.4)

Pass a long as a parameter, containing the value of the permissions that will
be assigned to newly created directories on the remote server. The default
value is \fI0755\fP, but any valid value can be used. The only protocols that
