Dean Moldovan 96997a4b9d Change internals ID and versioning scheme to avoid module conflicts ... The current PYBIND11_INTERNALS_ID depends on the version of the library in order to isolate binary incompatible internals capsules. However, this does not preclude conflicts between modules built from different (binary incompatible) commits with the same version number. For example, if one module was built with an early v2.2.dev and submitted to PyPI, it could not be loaded alongside a v2.2.x release module -- it would segfault because of incompatible internals with the same ID. This PR changes the ID to depend on PYBIND11_INTERNALS_VERSION which is independent of the main library version. It's an integer which should be incremented whenever a binary incompatible change is made to internals. PYBIND11_INTERNALS_KIND is also introduced for a similar reason. The same versioning scheme is also applied to `type_info` and the `module_local` type attribute.		2017-08-23 10:44:52 +02:00
