Christopher Faulet cb5501327c BUG/MINOR: http-rules: Remove buggy deinit functions for HTTP rules
Functions to deinitialize the HTTP rules are buggy. These functions does not
check the action name to release the right part in the arg union. Only few info
are released. For auth rules, the realm is released and there is no problem
here. But the regex <arg.hdr_add.re> is always unconditionally released. So it
is easy to make these functions crash. For instance, with the following rule
HAProxy crashes during the deinit :

      http-request set-map(/path/to/map) %[src] %[req.hdr(X-Value)]

For now, These functions are simply removed and we rely on the deinit function
used for TCP rules (renamed as deinit_act_rules()). This patch fixes the
bug. But arguments used by actions are not released at all, this part will be
addressed later.

This patch must be backported to all stable versions.
