For a long time we had two large accept() functions, one for TCP sockets instanciating proxies, and another one for UNIX sockets instanciating the stats interface. A lot of code was duplicated and both did not work exactly the same way. Now we have a stream_sock layer accept() called for either TCP or UNIX sockets, and this function calls the frontend-specific accept() function which does the rest of the frontend-specific initialisation. Some code is still duplicated (session & task allocation, stream interface initialization), and might benefit from having an intermediate session-level accept() callback to perform such initializations. Still there are some minor differences that need to be addressed first. For instance, the monitor nets should only be checked for proxies and not for other connection templates. Last, we renamed l->private as l->frontend. The "private" pointer in the listener is only used to store a frontend, so let's rename it to eliminate this ambiguity. When we later support detached listeners (eg: FTP), we'll add another field to avoid the confusion.
