locale/C-numeric.c, locale/C-time.c: Change copyright.
* locale/C-ctype.c (_nl_C_LC_CTYPE_class32): Correct
endianess for initialization value.

for width information.

(ctype_finish): Make sure all characters named in charset
width table are known to name table.
(ctype_output): Correct handling of class and map name
information and write out width information.
(find_idx): Prepare for being called with NULL pointer as
TABLE argument. This means only allocate name entry.

`ctype_output' with additional argument charset.

* stdlib/stdlib.h: Correct prototypes for __strto*_internal
functions.
* stdlib/strtod.c: Extend for use as `wcsto{f,d,ld}'.

* sysdeps/generic/confname.h: Add definition of _PC_SYNC_IO,
_PC_ASYNC_IO, _PC_PRIO_IO and _SC_CHARCLASS_NAME_MAX.
* sysdeps/generic/stpncpy.c: Correct return value.
* sysdeps/posix/fpathconf.c: Add handling of _PC_SYNC_IO,
_PC_ASYNC_IO, and _PC_PRIO_IO.
* sysdeps/posix/sysconf.c: Add handling of _SC_REALTIME_SIGNALS,
_SC_PRIORITY_SCHEDULING, _SC_TIMERS, _SC_ASYNCHRONOUS_IO,
