Headers are never included here or else get_http_headers would not
have been called.
As a result, custom files need to set FS_FILE_FLAGS_HEADER_PERSISTENT
in file->flags if file->len is the correct length of the file.

This patch moves in advance httpd_cgi_handler() call, before assigning
variables like hs->file and hs->left.
In this way, CGI handler could prepare the reply data and set the
"file properties", like file->data and file->len. At the exit, hs->file
and hs->left is correctly assigned.
The handler prototype says it can't access file pointer, however it is
simple to obtain it after setting LWIP_HTTPD_FILE_STATE that enables a
"file state" pointer. It is sufficient to assign file->state to file
itself in fs_open_custom().
For example, I have the request GET /login.cgi?user=admin&pwd=admin and
I have to reply with some JSON data. The answer depends on parameters
user and pwd passed in the query string.
This broke when IPv6 got scopes added. Scopes/zones are checked
even if none of the compared addresses are link local.
Result of the bug was that IPv6 replies were always sent unicast to
the source instead of to the multicast address.
Add ip-generic version that ignores IP zone info, since the v6 group
address is not tied to any netif.
Changes made by me:
- Move all error handling code into mdns_resp_announce() so it can be safely used by external code
- Remove mdns_resp_netif_settings_changed() because it is the same as mdns_resp_announce() after my changes
- Declare #define for a "thread-safe" version of mdns_resp_announce in mdns.h instead of netifapi.h - I don't want to intermix netif API with APPs
Use ip_addr_copy instead of ip_addr_set to avoid NULL test for
&sntp_last_server_address. This fixes build warning when
SNTP_CHECK_RESPONSE>=1 && LWIP_IPV4=1 && LWIP_IPV6=1.

This adds const to the sntp servername get/set API and internal storage
SNTP's usage of this name is read only and SNTP only passes it to dns_gethostbyname()
This was found by compiling with GCC -Wwrite-strings which makes the literal
SNTP_SERVER_ADDRESS a const string. This then produced warnings with sntp_init()'s
call to sntp_setservername()
The version check is done in these functions, it should be ok to put
assert in the else clause.
