Modified Files:
exec/load/dns.js
Log Message:
Add DNS_blocking sub-class for non-event driven lookups

The DNS_blocking class supports the same API as the DNS class, but
does not use events, so any method will complete before returning.
As such, the callback argument is optional.

Also, have handle_response() return errors.

Log Message:
Fixes for async lookups

- Add a unique number to event names for each request
Prevents responses from being acepted by multiple queries

- OPcode of 2 is used for status replies (ie: NXDOMAIN)
- Be more careful construct result array in request()

Log Message:
Throw a more helpful exception when no nameservers specified/available

My /etc/resolv.conf was wiped by Network Manager (gee, thanks), so
ircd.js was throwing the following unhelpful exceptions when starting
up:
Feb 25 13:47:51 git jsexec[19108]: !JavaScript : uncaught exception: Unable to create any sockets
Feb 25 13:47:51 git jsexec[19108]: !JavaScript : uncaught exception: Unable to create any sockets

First, instead of throwing a string, throw an Error object so we can
actually know where the exception ocurred. Please, everyone, throw Errors
not Strings.

Second, throw a different more helpful exception if there are no nameservers specified in the DNS constructor or configured on the system.

Log Message:
Don't return 0 when unable to parse integers.

0 is a valid value, results are undefined.

Validate the size of the message at each step and throw an error if
something goes wrong.

Should fix the issue where an IRC spammers DNS was detected as local,
so the anti-spammer bot banned my server address intead of the
spammers address.
