N_Expanded_Names that constitute the name of a child unit, do not
attempt to go further than Standard_Standard in the chain of scopes.

nonexistent child unit.

set _M_state_cur correctly, store the resulting state in
the return value and use _M_terminate_output to handle
flushing and unshift.
(basic_filebuf::_M_terminate_output): Flush contents of
output buffer, if any, then call codecvt::unshift as
needed and output the result.
(basic_filebuf::sync): Move here, don't modify _M_writing
or _M_reading.
