* include/bits/fstream.tcc (_M_overflow): Rewrote to call
_M_convert_to_external only once (_M_buf_size is now the size of
the put area + 1 for the overflow char of a full area); call
_M_set_buffer instead of _M_set_indeterminate.
(setbuf): Don't accept a buffer smaller than 2 chars.
(_M_underflow): Refill _M_buf_size - 1 chars; call _M_set_buffer,
instead of _M_set_determinate.
(open): Call _M_set_buffer, instead of _M_set_indeterminate.
(seekoff): Likewise.
* include/ext/stdio_filebuf.h (stdio_filebuf(int,
std::ios_base::openmode, bool, size_t),
stdio_filebuf(std::__c_file*, std::ios_base::openmode, size_t):
Likewise.
* include/std/std_fstream.h (_M_set_indeterminate): Remove.
(_M_set_determinate): Rename as _M_set_buffer, _M_buf_size ->
_M_buf_size - 1.
* include/std/std_streambuf.h: Tweak _M_out_lim comment.
* testsuite/27_io/basic_filebuf/sgetn/char/1.cc: Tweak, taking
into account that, for _M_buf_size == BUFSIZ == 8192, the size of
the put area is now BUFSIZ - 1.
* testsuite/ext/stdio_filebuf_2.cc: Tweak, taking into account
that now the smallest _M_buf_size is 2 (still fails, for the same
reason, with 3.2.3)
