Option 'ip_source' was silently ignored during public IP discovery.
Discovery (in spite of chosen 'ip_source') was based only on
'ip_network', 'ip_interface', 'ip_script' or 'ip_url' options (in this
order) if they were set. This could lead to misleading log entries
"Detect local IP on '$ip_source'" pointing to source that wasn't really
used.
Now only option relevant to configured 'ip_source' is taken into
account.

Since certain characters are dangerous to pass as-is to a sub shell,
sanitize the character set and only allow characters that are considered
valid for DNS hosts and filter shell escape characters on generic parameters.
Disable pathname expansion on RUNPROG evals to disable the shell expanding *,
? and [ in the arguments.

Currently this 3 variable are used only 1 time in the sh script and cause 10s of delay for them to load... move them to load only if it's required by the command. This also fix luci-app-ddns delay problem derived by calling dns_lucihelper (that use tdns_functions to load data) for the version.

- Add valid responses "good|nochg" so that ddns-script could recognize "badauth"
error that comes with http 200 code
- Switch url to https scheme. "now-dns.com" always returns 302 redirect
to https:// for all plain-text http requests. Since working via default
plain-text http is not possible anyway, forcing url to https prevents
curl sending unencrypted plain-text credentials via basic auth

Rewritten Pull for #5885
When ran from the command line, the script prints
error messages like below. They are caused by supplying
empty "$password" and "$URL_PASS" for some log messages
like "130822 : Detect local IP on 'interface'".
The fix is to check if the values are not empty before running
through sed.
/etc/init.d/ddns start
sed: no previous regexp

Assuming the following dns zone configuration for kresin.me:
. 1800 IN NS ns.inwx.de.
home.kresin.me. 1800 IN NS gw.home.kresin.me.
gw.home.kresin.me. 60 IN A 198.51.100.1
Using the example, gw.home.kresin.me is a glue record and used as DDNS
record as well. gw.home.kresin.me points to the OpenWrt installation
where the ddns-scripts are running.
Since ns.inwx.de isn't the authoritative server for home.kresin.me,
a query for the the A record of gw.home.kresin.me will be "forwarded"
to and replied by the authoritative server 198.51.100.1. If the
authoritative server can't be reached, the query times out without any
address returned.
The only way to get the A record of the glue record is to use bind
host in verbose output mode, query ns.inwx.de for gw.home.kresin.me and
evaluate the additional section of the response.
To my knowledge, only bind host in verbose output mode shows the
additional section of the response. Therefore, this features depends on
bind host.
It is not possible to use the bind host verbose mode for all queries.
In verbose mode the "has address" line isn't returned. Grepping for the
hostname might fail if the hostname is CNAME. Grepping for the first
occurrence of an ip-address is way to error prone, since it could
return the ip address of a different record type.
