The variable this->listsize is an unsigned int, but the format
string assumed ptrdiff_t. Found by Coverity.

Coverity points out that addr.len was potentially being used
uninitialized, via calls to in46a_inc(&addr).

When copying an address to a reused static hash table member
with memcpy(), this code mistakenly passed the size of a
pointer as the amount of bytes to be copied, rather than
the actual size of the address.
This means the IP pool could contain bogus IP addresses because
only addr->len (a uint8_t) and 3 further bytes of the address
were actually copied on 32 bit platforms. On 64 bit platforms,
a sufficient amount of bytes were copied for IPv4 to work
correctly, but too few bytes were copied for IPv6.
This problem was found by Coverity.
Replace the bogus memcpy() call with direct assignments to the
appropriate struct in64addr union members, and assert that the
length recorded for the address actually corresponds to the
length used by the address family (IP4, IPv6).

The calloc() call in ippool_new() had two problems.
The first problem is benign: The order of arguments were reversed.
Pass the number of elements in the array first, then the size of
each element, as calloc() expects.
This problem was found by me. There are more instances of this
problem in this file, which I'll address in follow-up patches.
The second problem is that the requested allocation was larger than
necessary: The hash table is an array of pointers to ippoolm_t, not
an array of struct ippoolm_t. Fix the required size passed to calloc().
This problem was found by Coverity.

* we have to use stataddr, not addr (dynamic)
* we have to multiply the length of the address by 8 to get its bit length
* we can simplify the -1 +1 logic (like dynamic)

Commit dda21ed7d4 modified previous calls
to ippool_new() removing the pass of flags to avoid allocating certain
problematic IPs from the pool to MS, such as the network, gateway and
broadcast IPs.
Today I did some unsucessful tests with osmo-ggsn with a pool "ip prefix
dynamic 176.16.222.0/24", and thus IP 176.16.222.0 was being assigned to
the MS. De-capsulated DNS packets were received in the tun interface,
but the Linux system in there was unable to correctly forward the
packets to the gateway interface connected to the Internet. However,
adding a second MS which got 176.16.222.1 had its packets forwarded
correctly.
However, previous implementation relies on flag IPPOOL_NOGATEWAY flag to
blindly blacklist first IP after the network ip (ie, .0 and .1 are
removed), which limits the IP reserved for the tun device to be .1. If a
different IP in the range is assigned, it may cause issues. As a result,
a blacklist is introduced in this commit to dynamically fetch the tun IP
address and exlucde it from the pool of available IPs.

Take the chance this commit is changing test output to also remove use
of IPPOOL_NOGATEWAY which is going to be removed soon, and instead test
IPPOOL_NOBROADCAST.

In IPv6 GPRS, we actually don't want to allocate an individual v6
address (like in IPv4), but we want to allocate a prefix. The
standard prefix lengh is 8 bytes, i.e. a /64 prefix. This patch
extends the pool to be able to work with such v6 prefixes.

When we receive PDP context requests for unknown PDP types or if
we run out of dynamic addresses, we need to inform the SGSN that
PDP context creation failed.

Extend the IP pool implementation to be able to manage both pools
of 32bit addresses (IPv4) as well as pools of 128bit addresses (IPv6)

After so many years of silence, we don't expect the original author to
return to the project. To make things a bit simpler for us, we convert
the coding style to what we are used to (Linux style).
The conversion was made using the 'Lindent' script which is part of the
Linux kernel.
Some files like in sgsnemu and ggsn directory where exactly the same.
They are now moved to the same directory for easier maintenance
