* include/std/std_fstream.h (_M_filepos): Remove.
(_M_reading, _M_writing): New, encode the various I/O modes:
'read', 'write' and 'uncommitted'.
(sync): If there is something to flush, do it, then go to
'uncommitted' mode.
* include/bits/fstream.tcc (_M_set_buffer): Overhaul to deal
with three different cases: __off > 0 (upon underflow),
__off == 0 (upon overflow), __off == -1 (upon open, setbuf,
seekoff/pos).
(_M_underflow): Don't call overflow, set _M_reading to true
on success, tweak.
(pbackfail): Set _M_reading to true on pback creation, tweak.
(overflow): Don't seek, deal with overflow in 'uncommitted' mode,
set _M_writing to true on success, tweak.
(seekoff): Simplify, set _M_reading, _M_writing to false, call
_M_set_buffer(-1) ('uncommitted').
(open, close, setbuf): Set _M_reading, _M_writing to false and
call _M_set_buffer(-1), tweak.
(basic_filebuf): Don't set _M_buf_unified.
(_M_destroy_internal_buffer): Don't call setg and setp.
* include/ext/stdio_filebuf.h (stdio_filebuf): Use _M_reading,
_M_writing and _M_set_buffer(-1).
* include/std/std_streambuf.h (_M_move_out_cur, _M_move_in_cur,
_M_out_lim, _M_buf_unified): Remove.
(basic_streambuf): Don't set _M_out_lim and _M_buf_unified.
(setp): Don't set _M_out_lim.
* testsuite/27_io/basic_filebuf/sbumpc/char/1-io.cc: Fix for
the new logic ('read', 'write' and 'uncommitted' modes): e.g.,
upon open the mode is 'uncommitted' and therefore the put area
pointers are null.

documented derivation interface to basic_streambuf (gptr(),
setg(), etc.) to work right with user specializations.
