Redesigned virtual call mechanism and user-facing syntax (breaking change!) Sergey Lyskov pointed out that the trampoline mechanism used to override virtual methods from within Python caused unnecessary overheads when instantiating the original (i.e. non-extended) class. This commit removes this inefficiency, but some syntax changes were needed to achieve this. Projects using this features will need to make a few changes: In particular, the example below shows the old syntax to instantiate a class with a trampoline: class_<TrampolineClass>("MyClass") .alias<MyClass>() .... This is what should be used now: class_<MyClass, std::unique_ptr<MyClass, TrampolineClass>("MyClass") .... Importantly, the trampoline class is now specified as the *third* argument to the class_ template, and the alias<..>() call is gone. The second argument with the unique pointer is simply the default holder type used by pybind11.

Fix #283: don't print first arg of constructor This changes the exception error message of a bad-arguments error to suppress the constructor argument when the failure is a constructor. This changes both the "Invoked with: " output to omit the object instances, and rewrites the constructor signature to make it look like a constructor (changing the first argument to the object name, and removing the ' -> NoneType' return type.

Improve constructor/destructor tracking This commit rewrites the examples that look for constructor/destructor calls to do so via static variable tracking rather than output parsing. The added ConstructorStats class provides methods to keep track of constructors and destructors, number of default/copy/move constructors, and number of copy/move assignments. It also provides a mechanism for storing values (e.g. for value construction), and then allows all of this to be checked at the end of a test by getting the statistics for a C++ (or python mapping) class. By not relying on the precise pattern of constructions/destructions, but rather simply ensuring that every construction is matched with a destruction on the same object, we ensure that everything that gets created also gets destroyed as expected. This replaces all of the various "std::cout << whatever" code in constructors/destructors with `print_created(this)`/`print_destroyed(this)`/etc. functions which provide similar output, but now has a unified format across the different examples, including a new ### prefix that makes mixed example output and lifecycle events easier to distinguish. With this change, relaxed mode is no longer needed, which enables testing for proper destruction under MSVC, and under any other compiler that generates code calling extra constructors, or optimizes away any constructors. GCC/clang are used as the baseline for move constructors; the tests are adapted to allow more move constructors to be evoked (but other types are constructors much have matching counts). This commit also disables output buffering of tests, as the buffering sometimes results in C++ output ending up in the middle of python output (or vice versa), depending on the OS/python version.

Track registered instances that share a pointer address The pointer to the first member of a class instance is the same as the pointer to instance itself; pybind11 has some workarounds for this to not track registered instances that have a registered parent with the same address. This doesn't work everywhere, however: issue #328 is a failure of this for a mutator operator which resolves its argument to the parent rather than the child, as is needed in #328. This commit resolves the issue (and restores tracking of same-address instances) by changing registered_instances from an unordered_map to an unordered_multimap that allows duplicate instances for the same pointer to be recorded, then resolves these differences by checking the type of each matched instance when looking up an instance. (A unordered_multimap seems cleaner for this than a unordered_map<list> or similar because, the vast majority of the time, the instance will be unique).

Implement reference_internal with a keep_alive reference_internal requires an `instance` field to track the returned reference's parent, but that's just a duplication of what keep_alive<0,1> does, so use a keep alive to do this to eliminate the duplication.
