* include/bits/fstream.tcc: Delete _M_last_overflowed.
(basic_filebuf::basic_filebuf): Initialize _M_state_last.
(basic_filebuf::open, basic_filebuf::close): Assign
_M_state_beg to _M_state_cur and _M_state_last.
(basic_filebuf::close): Call _M_terminate_output to handle
unshift and flushing.
(basic_filebuf::underflow): Assign _M_state_last, throw
exception instead of calling abort when codecvt::max_length()
is bad.
(basic_filebuf::seekoff): Use _M_state_last when calling
codecvt::length(), pass correct state to _M_seek.
(basic_filebuf::seekpos): Pass __pos.state() to _M_seek.
(basic_filebuf::_M_seek): Add __state_type parameter,
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.
