"LogLevel SILENT" compatibility

"LogLevel SILENT" (-qq) was introduced in Debian openssh 1:3.0.1p1-1 to
match the behaviour of non-free SSH, in which -q does not suppress fatal
errors.  However, this was unintentionally broken in 1:4.6p1-2 and nobody
complained, so we've dropped most of it.  The parts that remain are basic
configuration file compatibility, and an adjustment to "Pseudo-terminal will
not be allocated ..." which should be split out into a separate patch.
