[3/3] qpid-proton git commit: PROTON-865: 0-overhead facades,
reference counting and smart ptr support.
PROTON-865: 0-overhead facades, reference counting and smart ptr support.
See proton/facade.hpp doc comments for details. The highlights:
- 0 overhead facade classes, facade pointers point directly at C structs.
- proton::counted_ptr for automated refcounting of proton objects in any C++ version.
- std:: and boost:: smart pointers supported as alternative to proton::counted_ptr.
- APIs take/return foo& for facade foo, facade can convert to smart pointer.
Tested with g++ and clang++ in c++03 and c++11 mode. Not tested on windows.
This is simpler and more obvious than the proposal floated on the proton list
but has essentially the same properties.

+Proton memory mangement
+=======================
+
+Proton is a collection of libraries in different programming langauges. Some of
+the libraries (e.g. C and Java) are written directly in those langauges. Some
+(e.g. python and ruby) are "bindings", native libraries that that internally use
+the C library. All the libraries provide a "native" memory management
+experience, you don't need to know anything about C or the proton C library to
+use them.
+
+If you only program in java, python, ruby or a similar garbage-collected
+language then you may be wondering "what is *memory management*?" Don't worry,
+the proton library takes care of it. However, as usual, you are responsible for
+some non-memory *resource* management. For example if you fail to `close()` a
+proton connection there won't be memory leaks but the remote end will get a rude
+"connection failed" error instead of an orderly connection close.
+
+If you are a C programmer, you are probably rolling your eyes and wondering why
+the kids these days expect their memory to be managed for them. Don't worry, the
+C API offers the standard C experience: you must call `pn_X_free` on a `pn_X_t*`
+when the time is right and you must know when a `pn_X_t*` can become invalid as
+a side effect of some other call. Read the doc, learn the rules and get it
+right. You are a C programmer!
+
+If you are a modern C++11 programmer and always use `shared_ptr` and
+`unique_ptr` to write leak-safe code, then the C++ binding is leak-safe. If you
+are stuck on C++03, the binding supports `boost::shared_ptr` and
+`boost::intrusive_ptr`. If you cannot even use boost, the binding provides a
+simple (type safe, intrusive) smart pointer of its own which can help you.
+
+If you are a Go programmer, you know that Go takes care of *Go-allocated* memory
+but you are responsible other resource cleanup, e.g. closing connections. Go
+does not have object-scoped cleanup (or indeed objects) but as a crafty Go
+programmer you know that function-scoped cleanup is all you really need, and
+`defer` is your friend. The Go binding internally starts goroutines and
+allocates memory that is not tracked by Go, so proper cleanup is important (but
+you knew that.)
+
+Proton reference counting in C
+------------------------------
+
+Internally, the proton C library uses reference counting, and you can
+*optionally* use it in your code. You should choose *either* reference counting
+*or* `pn_X_free` in your code, *not both*. It might work, but it is the sort of
+Bad Idea that might break your code in the future and will hurt your head in the
+present. `pn_X_free` is all you really need to write an AMQP application in C.
+
+However, proton is designed to be embedded and integrated. If you are
+integrating proton with a new programming language, or some other kind of
+framwork, reference counts may be useful. If your integration target has some
+form of automatic clean-up *and* some way for you to hook into it (finalizers,
+destructors or the like) then reference counts may help (e.g. python, ruby and
+C++). As a counter-example the Go langauge *is* garbage collected but does *not*
+have finalizers, and the Go binding does *not* use reference counts, it is
+written like a "normal" C application with `pn_X_free`.
+
+If you are mixing your own C code with code using a reference-counted proton
+binding (e.g. C++ or python) then you may need to at least be aware of reference
+counting.
+
+You can even use reference counts in plain C code if you find that helpful (I
+don't see how it would be but you never know.)
+
+The proton C API has standard reference counting rules (but see [1] below)
+
+- A pointer *returned* by a `pn_` function is either *borrowed* by the caller,
+ or the caller *owns* a reference (the API doc says which.)
+- The owner of a reference must call `pn_decref()` exactly once to
+ release it.
+- To keep a borrowed pointer, call `pn_incref()`. This adds a new
+ reference, which you now own.
+- A pointer *passed* to a `pn_` function has no change of ownership. If you
+ owned a reference you still do, if you didn't you still don't.
+- An object is never freed while there are still references to it.
+- An object is freed when all references to it are released.
+
+A *borrowed* pointer is valid within some scope (typically the scope of an event
+handling function) but beyond that scope you cannot assume it is valid unless
+you make a new reference with `pn_incref`. The API documentation for the
+function that returned the pointer should tell you what the scope is.
+
+There are "container" relationships in proton: e.g. a connection contains
+sessions, a session contains links. Containers hold a reference to their
+contents. Freeing a container *releases* that reference. For example freeing a
+connection releases its sessions.
+
+If you don't use reference counts, then freeing a container *frees* the contents
+in traditional C style. However if you add a reference to a contained object it
+will *not* be freed till you release your reference, even if all references to
+container are released [1]. This is useful for bindings to langauges with
+"finalizers" or "destructors". You can use reference counts to "pin" proton C
+objects in memory for as long as any binding object needs them.
+
+For example: if you call `pn_message()` then you *own* a reference to the
+newly-created `pn_message_t` and you must call `pn_decref` when you are
+done [2]. If you call `pn_event_link()` in an event handler then you get a
+*borrowed* reference to the link. You can use it in the scope of the event
+handler, but if you want to save it for later you must call `pn_incref`
+to add a reference and of course call `pn_decref` when you are done with
+that reference.
+
+[1] *Internally* the proton library plays tricks with reference counts to
+implement 'weak' pointers and manage circular containment relationships. You do
+*not* need to understand this to use proton, even if you are writing bindings or
+doing funky mixed-language development. However if you are working on the
+implementation of the proton C library itself you may need to learn more, ask on
+proton@qpid.apache.org.
+
+[2] Actually if you call `pn_message()` then you must *either* call
+`pn_decref()` *or* `pn_message_free()`, definitely not both. It is
+possible to mix reference couting and 'free' style memory management in the same
+codebase (`free` is sort-of an alias for `decref`) but it is probably not a good
+idea.
