Pygdbmi Versions Save

Breaking changes

• Removed pygdbmi.IoManager.make_non_blocking from the public API; it's unrelated and was not meant to be public

Other changes

• Fixed a bug where notifications without a payload were not recognized as such
• Invalid octal sequences produced by GDB are left unchanged instead of causing a UnicodeDecodeError (#64)
• Fix a crash on Windows by waiting for the GDB process to exit in GdbController.exit
• Added type annotations to the whole public API
• Updated the examples in README.md to use the current API and show the results printed by this version of pygdbmi (#69)

Internal changes

• Update and freeze dependencies for documentation generation
• Refactored the code to parse MI records to decrease the number of regex matches to perform
• Added __all__ to all modules, which means that star imports (like from pygdbmi.gdbmiparser import *) will not pollute the namespace with modules used by pygdbmi itself
• Added nox -s format to re-format the source code using the correct options
• Reformatted all imports with isort, and use it as part of nox -s lint and nox -s format
• Converted tests to use pytest's test structure rather than the unittest-based one
• Added mypy configuration to detect more problems and to force all code to be annotated
• Added a test for example.py
• Replaced uses of distutils.spawn.find_executable, which is deprecated, with shutil.which
• Ran pyupgrade (with option --py37-plus) on the codebase to convert to Python 3.7 idioms
• Excluded some common backup and cache files from MANIFEST.in to prevent unwanted files to be included which causes check-manifest to fail
• Fix .flake8 to not cause errors with some versions of the flake8 tool

0.10.0.0
