xargs: fix handling of quoted arguments, closes 11441
As reported in bug 11441 when presented with a large number of quoted
arguments xargs can return 'argument line too long':
seq 10000 29999 | sed -e 's/^/"/' -e 's/$/"/' | busybox xargs echo
This happens because the variant of process_stdin() which handles quoted
arguments doesn't preserve state between calls. If the allowed number
of characters is exceeded part way through a quoted argument the next
call to process_stdin() incorrectly treats the terminating quote as a
starting quote, thus quoting all of the argument separators.
