Chuck dd8fa11ac1 Support multiple address resolution in DNS requests
Add two new functions to the IP class that returns all addresses/aliases associated with a given address.

This is a cherry-pick merge from 010a3433df which was merged in 2.1, and has been updated to build with the latest code.

This merge adds two new methods IP.resolve_hostname_addresses and IP.get_resolve_item_addresses that returns a List of all addresses returned from the DNS request.

<method name="clear_cache">
<return type="void">
</return>
<argument index="0" name="hostname" type="String" default="&quot;&quot;">
</argument>
<description>
Removes all of a [code]hostname[/code]'s cached references. If no [code]hostname[/code] is given, all cached IP addresses are removed.

<method name="erase_resolve_item">
<return type="void">
</return>
<argument index="0" name="id" type="int">
</argument>
<description>
Removes a given item [code]id[/code] from the queue. This should be used to free a queue after it has completed to enable more queries to happen.
</description>
</method>
<method name="get_local_addresses" qualifiers="const">
<return type="Array">
</return>
<description>
Returns all the user's current IPv4 and IPv6 addresses as an array.
</description>
</method>
<method name="get_local_interfaces" qualifiers="const">
<return type="Array">
</return>
<description>
Returns all network adapters as an array.
Each adapter is a dictionary of the form:
[codeblock]
{
"index": "1", # Interface index.
"name": "eth0", # Interface name.
"friendly": "Ethernet One", # A friendly name (might be empty).
"addresses": ["192.168.1.101"], # An array of IP addresses associated to this interface.
}
[/codeblock]

<description>
Returns a queued hostname's IP address, given its queue [code]id[/code]. Returns an empty string on error or if resolution hasn't happened yet (see [method get_resolve_item_status]).
