[ipv6calc] ipv6calc: use shared libipv6calc.so and databases

[Peter Bieringer]

Hi Nikoli,

thank you for all the patches, applied. Also for others, RPM spec file
is now also working.

# rpm -qvl ipv6calc |egrep '/(bin|lib)'
-rwxr-xr-x 1 root root   87744 Feb  2 13:35 /usr/bin/ipv6calc
-rwxr-xr-x 1 root root   24216 Feb  2 13:35 /usr/bin/ipv6loganon
-rwxr-xr-x 1 root root   28216 Feb  2 13:35 /usr/bin/ipv6logconv
-rwxr-xr-x 1 root root   29368 Feb  2 13:35 /usr/bin/ipv6logstats
-rwxr-xr-x 1 root root  410488 Feb  2 13:35 /usr/lib64/libipv6calc.so.0.96.0
-rwxr-xr-x 1 root root 2588192 Feb  2 13:35
/usr/lib64/libipv6calc_db_wrapper.so.0.96.0


=> size of binaries reduced, database information is now mostly in
libipv6calc_db_wrapper.so (leftovers in libipv6calc.so will be moved next)


BTW1: install was not tested so far, sorry!

BTW2: switch from CVS to GIT is planned, but not on top priority at the
moment unfortunately because lack of time.

Hope this helps!

Regards,
	Peter
