Added support for RFC 959's REST command (restart), closing SF patch
#101187, which some modifications. Specifically,
ntransfercmd(), transfercmd(), and retrbinary() all grow an optional
`rest' argument, which if not None, is used as the argument to an FTP
REST comman dbefore the socket is returned. Differences from the SF
patch:
- always compare against None with `is' or `is not' instead of == or !=
- no parens around conditional
- RFC 959 defines the argument to REST is a string containing any
ASCII characters in the range [33..126]. Therefore, we use the %s
format character instead of %f or %d as suggested in the patch's
comments. Note that we do /not/ sanity checkthe contents of the
rest argument (but we'll document this in the library reference
manual).
