Fixes CVE-2017-11185:
Fixed a DoS vulnerability in the gmp plugin that was caused by insufficient input validation
when verifying RSA signatures, which requires decryption with the operation m^e mod n,
where m is the signature, and e and n are the exponent and modulus of the public key.
The value m is an integer between 0 and n-1, however, the gmp plugin did not verify this.
So if m equals n the calculation results in 0, in which case mpz_export() returns NULL.
This result wasn't handled properly causing a null-pointer dereference.

the ntp initskript will only run at first connection try. If this fails
and the connection can established later DNS will not work if the clock
is too far away.

Unbound was trying to check availability of the upstream name servers
when /var/ipfire/red/active is present. This patch removes it first
and then brings down the red device.

The old algorithm could potentially lock itself in an endless
recursion when there were packages with circular dependencies.
This version does not do this and is also faster.

Some hosters require that the subnet mask of the RED network
is set to 255.255.255.255. This was not possible to save before.

When an on-demand VPN connection is not up, the packets will
traverse the firewall and be rejected by the IPSECBLOCK chain
which will cause that an ICMP error message will be sent to
the client. If that does not happen and the packet is being
silently dropped, the client will retransmit and by then
the VPN connection will hopefully be up.

This reverts commit ff6cc71107.
This patch causes that no new networks can be created and
an error message is shown that the created network is the GREEN
network which is incorrect.

The graphs are using an iframe and PNG images where the resolution
did often not fit and the browser had to resize the image. That
led to blurred fonts and hard to read graphs.
This patch increases the size of the box and the image. With that
higher resolution resizing should not be too much of an issue, but
since the sizes of the iframe and image have been aligned should
not even be necessary.

IPFire 2 does not have IPv6 connectivity with exception of a
few systems for testing where IPsec connections become a little
bit unstable when trying to connect over IPv6.

In large networks, when ever multiple clients connect at the
same time and request the proxy.pac configuration file, apache
rate-limited requests so that some clients did not get a response
and therefore could not connect to the Internet.
This allows apache to handle more connections at the same time.

The tests when assigning DNS name servers has been extended so that
if no working forwarder can be found, we will test if the local recursor
mode is an option.
If not, we will configure unbound's validator module into permissive
mode so that at least some DNS functionality is available.
