[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.

REORG/MAJOR: session: rename the "session" entity to "stream" With HTTP/2, we'll have to support multiplexed streams. A stream is in fact the largest part of what we currently call a session, it has buffers, logs, etc. In order to catch any error, this commit removes any reference to the struct session and tries to rename most "session" occurrences in function names to "stream" and "sess" to "strm" when that's related to a session. The files stream.{c,h} were added and session.{c,h} removed. The session will be reintroduced later and a few parts of the stream will progressively be moved overthere. It will more or less contain only what we need in an embryonic session. Sample fetch functions and converters will have to change a bit so that they'll use an L5 (session) instead of what's currently called "L4" which is in fact L6 for now. Once all changes are completed, we should see approximately this : L7 - http_txn L6 - stream L5 - session L4 - connection | applet There will be at most one http_txn per stream, and a same session will possibly be referenced by multiple streams. A connection will point to a session and to a stream. The session will hold all the information we need to keep even when we don't yet have a stream. Some more cleanup is needed because some code was already far from being clean. The server queue management still refers to sessions at many places while comments talk about connections. This will have to be cleaned up once we have a server-side connection pool manager. Stream flags "SN_*" still need to be renamed, it doesn't seem like any of them will need to move to the session.

BUG/MEDIUM: unix: completely unbind abstract sockets during a pause() Abstract namespace sockets ignore the shutdown() call and do not make it possible to temporarily stop listening. The issue it causes is that during a soft reload, the new process cannot bind, complaining that the address is already in use. This change registers a new pause() function for unix sockets and completely unbinds the abstract ones since it's possible to rebind them later. It requires the two previous patches as well as preceeding fixes. This fix should be backported into 1.5 since the issue apperas there.

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.
