[MAJOR] implemented client-side support for PF_UNIX sockets A new file, proto_uxst.c, implements support of PF_UNIX sockets of type SOCK_STREAM. It relies on generic stream_sock_read/write and uses its own accept primitive which also tries to be generic. Right now it only implements an echo service in sight of a general support for start dumping via unix socket. The echo code is more of a proof of concept than useful code.

/*
[MEDIUM] separate protocol-level accept() from the frontend's 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.

BUG/MEDIUM: stream_interface: restore get_src/get_dst Commit e164e7a removed get_src/get_dst setting in the stream interfaces but forgot to set it in proto_tcp. Get the feature back because we need it for logging, transparent mode, ACLs etc... We now rely on the stream interface direction to know what syscall to use. One benefit of doing it this way is that we don't use getsockopt() anymore on outgoing stream interfaces nor on UNIX sockets.
