Subject: [PATCH] Replace zero-length arrays with pointers.
MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

There are two zero-length arrays used, in struct
isns_hdr and struct isns_tlv, that are really meant
as place-holders for allocated arrays. These should
just be pointers.

This fixes a gcc-10 warning that looks like:

In function ‘isns_rsp_handle’,
    inlined from ‘isns_handle’ at .../src/isns.c:789:3:
.../src/isns.c:724:34: error: writing 1 byte into a region of size 0 [-Werror=stringop-overflow=]
  724 |    *((char *) tlv->value + slen) = '\0';
      |                                  ^
.../src/isns.c: In function ‘isns_handle’:

      |           ^
