Teach Net_IPv6:compress to handle a compressed address as input

Do not allow 1:2:3:4:5:6:7:8::9 as an IPv6 address

The Net_IPv6 code has a bug - checkIPv6 returns "true" for addresses like:
1::2:3:4:5:6:7:8:9
1:2::3:4:5:6:7:8:9
...
1:2:3:4:5:6:7::8:9
1:2:3:4:5:6:7:8::9
these also emit the message:
Warning: str_repeat(): Second argument has to be greater than or equal to 0 in /etc/inc/IPv6.inc on line 496...

Remove trailing carriage return

Fix line endings on remaining files that did not have the same line endings as everything else.
