BUG/MINOR: http: Missing calloc return value check in make_arg_list
A memory allocation failure happening in make_arg_list when trying to
allocate the argument list would have resulted in a crash. This function
is only called during configuration parsing.
It was raised in GitHub issue #1233.
It could be backported to all stable branches.
