* include/std/std_streambuf.h (_M_move_out_cur): _M_out_lim
is now used only for filebuf, when _M_buf_unified is true.
epgtr() plays the role of _M_out_lim but it's only updated
upon overflow, underflow, uflow, seekoff/pos.
* include/bits/sstream.tcc (_M_underflow): New, implements
stringbuf::underflow and uflow.
(seekoff, seekpos): Tweak, use _M_update_egptr.
* include/std/std_sstream.h (str): Rewrote, deal correctly
with the new logic, in particular, when pptr() > egptr().
(_M_sync): When __testout && !__testin set all the get area
pointers to the current string end.
(_M_update_egptr): New, internal function updating egptr()
to the actual string end.
(_M_underflow): New, declare.
(underflow): Dispatch to _M_underflow(false).
(uflow): Dispatch to _M_underflow(true).
* include/bits/sstream.tcc (pbackfail, overflow, seekoff,
seekpos): Use only the documented derivation interface to
basic_streambuf (gptr(), setg(), etc.) to work right with
user specializations.
* include/std/std_sstream.h (str, _M_sync): Likewise.

* safe-ctype.c: Use HOST_CHARSET_ASCII and HOST_CHARSET_EBCDIC,
not HC_ASCII and HC_EBCDIC.
Add documentation in form expected by gather-docs.
* hex.c: Use HOST_CHARSET, not hand-coded check of character set.
* Makefile.in, functions.texi: Regenerate.
gcc:
* config/i370/i370.c, config/i370/i370.h: Use HOST_CHARSET_ASCII
