Manage expiration times via a heap queue.
...
This prevents nsock from iterating over the whole list of events at
each runloop, thus improving performance.
It made it necessary to have pointers from the msevents to the event
lists they belong to. The patch therefore also changes gh_list from
autonomous containers to embedded structures.
Added unit tests accordingly and cosmetic changes to make things look
more consistent.

Update the Nmap copyright/license files. This isn't the new Nmap Public Source License we've been discussing on the list, but rather just a 'quick patch' to hopefully prevent some of the abuse we've been seeing from companies lately. More details on the changes will be posted to the dev list. Also, the copyright year was updated to 2013 (which is the only change to Nsock license statements).

Replaced proxy_chain->specstr by node->nodestr.

The global proxy chain specification string wasn't
used anywhere, and I'd need a string to represent
each node of the chain.

Removed the proxy-specific tcp_connect hook.
...
This simplifies the interface that proxies export to the library but also relies
upon the assumption that a proxy chain starts with a TCP connection from the
scanner to the next hop proxy. That will be enough ATM.

Added skeletton for having px_info list in each Nsock IOD.
...
When establishing the tunnel through proxy chain, we need to track status of
each proxy (storing R/W buffers, stats, retries...).
This patch lets proxies store and manage whatever structure they want to have
for this in a Nsock IOD. Since types can differ between proxy types, the
proxy_info are stored as a list of void *, ordered like the proxy nodes.

Refactored proxy code to use a "strategy" design pattern.
...
Proxy backends are selected at runtime. Each proxy exports a list of operations
to the rest of the library. This is similar to the way IO engines are
implemented within nsock.
