6b7b428cb9 Remove COMPAT_SRCS and COMPAT_OBJS. 
These appear not to have any effect any more. They were initially used
to conditionally compile and link some files with replacements for
standard library functions, but seem not to have been used after r828
("Moved to nbase system for compatability funcs").

ce01e2040a Refactored code. 
A switch/case reads easier than a if/else if/else block
to handle multiple cases.

153d3e695c Reverted r30784. 
The socks4_data structure is not aligned. Sending sizeof(sock4) bytes
results in invalid requests.

7c1f9aa780 Removed a kinda brutal assert(0); 
Don't abort when a socks4 proxy returns an invalid message,
just ignore it instead.

157922dfe0 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.

5cf3780a93 Added a nsock log message to nsock_connect_internal.

b54590c344 Don't artificially increase timeouts to establish proxy

values accordingly.

ab6a7a4f9e Added SOCKS4 support 
Beware socks4a extention is not supported. Target hostnames
therefore need to be resolved somehow.

af59333757 Perform the proxy connexion hook in connect_internal(). 
This allows to generically handle all kinds of connexions instead of manually
providing a handler for tcp connect, ssl connect...

The drawback is that would it makes it harder to implement support of SSL
proxies. Not sure whether there's a need though, looks like regular clients
don't handle them at least.
