BUG/MINOR: http-act: Properly generate 103 responses when several rules are used

When several "early-hint" rules are used, we try, as far as possible, to
merge links into the same 103-early-hints response. However, it only works
if there is no ACLs. If a "early-hint" rule is not executed an invalid
response is generated. the EOH block or the start-line may be missing,
depending on the rule order.

To fix the bug, we use the transaction status code. It is unused at this
stage. Thus, it is set to 103 when a 103-early-hints response is in
progress. And it is reset when the response is forwarded. In addition, the
response is forwarded if the next rule is an "early-hint" rule with an
ACL. This way, the response is always valid.

This patch must be backported as far as 2.2.
