Made proxy handlers return errors to caller when unable to handle proxy replies.
...
Errors are returned internally as -1 * <errno code>.

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.

Don't artificially increase timeouts to establish proxy

connections. It's now up to the caller to adjust timeout
values accordingly.

Removed per-node information structures as well as data encoding/decoding

interface.
These were unused and I think won't be required by any proxy type (HTTP and
SOCKS).

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.
