Subject: [PATCH] dhcpv6-ia: add missing limits header
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Fix the following build error by including <limits.h>:
src/dhcpv6-ia.c: In function 'handle_addrlist_change':
src/dhcpv6-ia.c:495:53: error: 'INT_MAX' undeclared (first use in this function)
  495 |                                         a->fr_cnt = INT_MAX;
      |                                                     ^~~~~~~
src/dhcpv6-ia.c:33:1: note: 'INT_MAX' is defined in header '<limits.h>'; did you forget to '#include <limits.h>'?

src/dhcpv6-ia.c:495:53: note: each undeclared identifier is reported only once for each function it appears in

      |                                                     ^~~~~~~
