* 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 dda21ed7d4a897c9284c69175d0da598598eae40 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.

we rather pass the in46_prefix directly into ippool_new()

This allows us to remove pool members without having to keep
a pointer to the pool around.

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
