As we can now have PDP contexts with IPv6 user IP payload,
it is useful to extend the TUN related code to be able to
configure the tun device IPv6 address + prefix length

Return early when socket() returns -1, and check return codes
where indicated by some TODOs. This removes 2 TODOs and fixes
a compiler warning about assignment to a variable which then
isn't used.

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.
* Change arguments of tun_gifindex from:
int tun_gifindex(struct tun_t *this, int *index)
to
int tun_gifindex(struct tun_t *this, __u32 *index)
solves:
../lib/tun.c: In function ‘tun_addaddr’:
../lib/tun.c:265: warning: pointer targets in passing argument 2 of
‘tun_gifindex’ differ in signedness
../lib/tun.c:88: note: expected ‘int *’ but argument is of type ‘__u32
*’
* handle system return code and returns -1 if system failed
solves:
../lib/tun.c: In function ‘tun_runscript’:
../lib/tun.c:895: warning: ignoring return value of ‘system’, declared
with attribute warn_unused_result
* do not dereference a pointer cast and use it as an lvalue

Some files like in sgsnemu and ggsn directory where exactly the same.
They are now moved to the same directory for easier maintenance
