stdio: provide _unlocked variants of fflush, fputc, fputs, fread, fwrite
fflush_unlocked is currently desired in ports by sysutils/metalog, and
redefined as the locked fflush.
fputc_unlocked, fputs_unlocked, fread_unlocked, and fwrite_unlocked are
currently desired in ports by devel/elfutils, and redefined as the locked
fputs, fread, and fwrite respectively.
