Description:
------------
mod_htscanner.c does not compile apxs2 (Apache 2.2.17)

Fix:
#include "httpd.h"
#include "http_config.h"
#include <stdio.h>

module AP_MODULE_DECLARE_DATA htscanner_module;

static const char *dummy(cmd_parms *cmd, void *config, const 
char *arg) {
    return (NULL);
}

static command_rec htscanner_cmds[] = {
    AP_INIT_ITERATE("php_flag", dummy, NULL, OR_OPTIONS, 
"PHP Flag Modifier"),
    AP_INIT_ITERATE("php_value", dummy, NULL, OR_OPTIONS, 
"PHP Value Modifier"),
    { NULL }
};

module AP_MODULE_DECLARE_DATA htscanner_module =
{
    STANDARD20_MODULE_STUFF,
    NULL,			   /* dir config creater */
    NULL,                          /* dir merger --- default 
is to override */
    NULL,                          /* server config */
    NULL,                          /* merge server config */
    htscanner_cmds,               /* command apr_table_t */
    NULL                           /* register hooks */
};

Expected result:
----------------
mod_htscanner compile for Apache 2 (2.2.17 and future)

Actual result:
--------------
mod_htscanner does not compile for Apache 2 (2.2.17)
