* Removing everything related to 2.7 from ci.yml
* Commenting-out Centos7
* Removing `PYTHON: 27` from .appveyor.yml
* "PY2" removal, mainly from tests. C++ code is not touched.
* Systematic removal of `u` prefix from `u"..."` and `u'...'` literals. Collateral cleanup of a couple minor other things.
* Cleaning up around case-insensitive hits for `[^a-z]py.*2` in tests/.
* Removing obsolete Python 2 mention in compiling.rst
* Proper `#error` for Python 2.
* Using PY_VERSION_HEX to guard `#error "PYTHON 2 IS NO LONGER SUPPORTED.`
* chore: bump pre-commit
* style: run pre-commit for pyupgrade 3+
* tests: use sys.version_info, not PY
* chore: more Python 2 removal

* Add py::raise_from to enable chaining exceptions on Python 3.3+
* Use 'raise from' in initialization
* Documenting the exact base version of _PyErr_FormatVFromCause, adding back `assert`s.

* Create a module_internals struct
Since we now have two things that are going to be module local, it felt
correct to add a struct to manage them.
* Add local exception translators
These are added via the register_local_exception_translator function
and are then applied before the global translators
* Add unit tests to show the local exception translator works
* Fix a bug in the unit test with the string value of KeyError
* Fix a formatting issue
* Rename registered_local_types_cpp()
Rename it to get_registered_local_types_cpp() to disambiguate from the
new member of module_internals
* Add additional comments to new local exception code path
* Add a register_local_exception function
* Add additional unit tests for register_local_exception
* Use get_local_internals like get_internals
* Update documentation for new local exception feature
* Add back a missing space
* Clean-up some issues in the docs
* Remove the code duplication when translating exceptions
Separated out the exception processing into a standalone function in the
details namespace.
Clean-up some comments as per PR notes as well
* Remove the code duplication in register_exception
* Cleanup some formatting things caught by clang-format
* Remove the templates from exception translators
But I added a using declaration to alias the type.
* Remove the extra local from local_internals variable names
* Add an extra explanatory comment to local_internals
* Fix a typo in the code
* Change base parameter type in register_exception and excepion constructor from PyObject* to handle
* Fix compilation error passing `handle` to `PyObject*`
The main change is to treat error_already_set as a separate category
of exception that arises in different circumstances and needs to be
handled differently. The asymmetry between Python and C++ exceptions
is further emphasized.
To deal with exceptions that hit destructors or other noexcept functions.
Includes fixes to support Python 2.7 and extends documentation on
error handling.
