Make sure Drupal provides support for IPv6 [#475140]

The column 'hostname' in core tables is defined as varchar(128), but the the column 'ip' in {blocked_ips} table is defined as varchar(32), which is a bug in D7, I think.

There's an additional issue that could be reviewed... I'm not sure if there are other places to review to make sure Drupal fully supports IPv6 (validations, preg, etc.), but maybe it would worth to check it out, just in case. The reason for this is: IPv6ActNow which is operated by RIPE NCC itself.

This one is pretty interesting reading:

To quote todays report:

- "Projected IANA Unallocated Address Pool Exhaustion: 06-Sep-2011"
- "Projected RIR Unallocated Address Pool Exhaustion: 31-Aug-2012"

IPv4 exhaustion counters:

http://ipv6.he.net/statistics/ (ByeBye v4 Hurricane Electric has a series of applications, widgets and JavaScript snippets to display the estimated exhaustion time and rate of IPv4, and the growing adoption of IPv6.)

The lenght of an IPv6 address is 40 characters, for the record:

$ echo 0000:0000:0000:0000:0000:0000:0000:0001 | wc
1 1 40

I started to tag issues in the queue with the "ipv6" tag. There are only two other issues right now.

Here's a patch that fixes the ip field in the blocked list. I am certain there are other culprits, for example #523286: Cleanup IP blocking fixes the form in a similar way.
