SquidDev 585c769c2a Restructure the HTTP API ...

- Adds support for blacklisting domains
 - Adds support for blacklisting & whitelisting IP addresses and
   IP ranges.
 - Reuse threads for HTTP requests

AddressPredicate will parse a series of patterns and convert them into
regexes or CIDR ranges. When checking whether an address is accessible,
we first ensure the domain is whitelisted and isn't blacklisted.

If everything is OK, then we start create a new thread for the HTTP
request and resolve the IP, ensuring that is whitelisted & not
blacklisted. Then the normal HTTP request is continued.

However, http.checkURL also needs to resolve the IP address. In order to
avoid blocking the Lua thread, this method will return instantly and
create a new thread which will queue an event.

As both http.request and http.checkURL are now creating threads and
queuing events, some logic is abstracted into a separate HTTPTask class
- this allows us to share the thread creation, finishing and cancelling
logic.
