FTP: misc fixes resulting from my testing.

- "total ..." lines can have values bigger than 32-bit
- some servers use "l" as a flag in permission listing
- some servers prepend garbage to the month column
- NetWare directory listings can have spaces in file names
- one additional variant of VMS error message

BUG=none
