        basesrc/lib/libc/locale: setlocale.c

Log Message:
fix a bug of setlocale when changing locales with LC_ALL for the first
argunemt and with a string containing many slashes for the second argument.
This bug may cause setlocale() to destroy static datas.

If a setuid program calls this function as 'setlocale(LC_ALL, "");',
this might be vulnerable, although there are few programs having such
vulnerability.  This bug probably affects every versions of NetBSD,
including 1.4, 1.5 and 1.6.

XXX: This part of setlocale is unseemly, thus we had better rewrite it in
the future.
