pfPorts: Sync unbound 1.4.19 (FreeBSD r308903), disable ECDSA

Sync with FreeBSD ports for a regular unbound release, try to stay
as close as possible.

We have to disable ECDSA support until we ship OpenSSL 1.0 as ECDSA
requires this newer OpenSSL version not present in base FreeBSd 8.3.
The upstream project denotes it 0.9.8 would work, but has known issues.
(Reference: unbound 1.4.17 release notes)
Replace spaces with tabs
Replace spaces with tabs
Fix type of l parameters in zend_parse_parameters
Use ! to allow NULL as a parameter
Actually free pending data to not be leaked
If a SIGHUP comes in force the update of the addresses on the table since usually this happens during a filter reload
Clear the flag of resynch after doing the sync
Do the clear under the main lock to avoid issues during TERM signal
Do not keep around an entry that matched existing host
Remove redundant check
Merge pull request #78 from bcyrill/php53-pf_type

Fix type of l parameters in zend_parse_parameters
Check length of string of user to that of the system to avoid a potential weakness of using str[n]cmp issues and thus mitigate XSS potentials in security
pfPorts: Remove pecl-radius port, directly use FreeBSD ports.

We had a unmodified port, upstream still ships same version,
but includes a PHP 5.4 patch.

Now directly use their port which reduces churn once we switch
to this version of PHP.
pfPorts: Rename openvpn-ipv6 as openvpn22

Do similar what FreeBSD ports does with legacy ports, now with
3 version of OpenVPN and 2.3 supporting IPv6 without extra patch,
rename to 2.2.
Have a Version -v option to be shown for filterdns to see if during upgrade issues arise.
Need to put it on the format list as wlel
Teach the multiple instance patch for ipfw and ipfw binary to set the context directly to avoid Ticket #2633
Rvert partially pull request #78 and properly handle 64bits of data.
Correct build!
