Port tests to pytest Use simple asserts and pytest's powerful introspection to make testing simpler. This merges the old .py/.ref file pairs into simple .py files where the expected values are right next to the code being tested. This commit does not touch the C++ part of the code and replicates the Python tests exactly like the old .ref-file-based approach.

Rename examples files, as per #288 This renames example files from `exampleN` to `example-description`. Specifically, the following renaming is applied: example1 -> example-methods-and-attributes example2 -> example-python-types example3 -> example-operator-overloading example4 -> example-constants-and-functions example5 -> example-callbacks (*) example6 -> example-sequence-and-iterators example7 -> example-buffers example8 -> example-custom-ref-counting example9 -> example-modules example10 -> example-numpy-vectorize example11 -> example-arg-keywords-and-defaults example12 -> example-virtual-functions example13 -> example-keep-alive example14 -> example-opaque-types example15 -> example-pickling example16 -> example-inheritance example17 -> example-stl-binders example18 -> example-eval example19 -> example-custom-exceptions * the inheritance parts of example5 are moved into example-inheritance (previously example16), and the remainder is left as example-callbacks. This commit also renames the internal variables ("Example1", "Example2", "Example4", etc.) into non-numeric names ("ExampleMandA", "ExamplePythonTypes", "ExampleWithEnum", etc.) to correspond to the file renaming. The order of tests is preserved, but this can easily be changed if there is some more natural ordering by updating the list in examples/CMakeLists.txt.

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.
