Makefile edits to improve library lint target support.
Makefile
--------
o Replace inlined includes with single $(MAKEDIR)/include.mk
o virtualenv install w/dependencies handled by makefiles/virtualenv.mk
o Use '&&' for command separation to improve error handling.
o Added more target documentation.
o Re-home doc8/rst syntax checking into makefiles/lint/doc8.mk.
howto/code/linting.rst
----------------------
o Document supported lint targets on docs.voltha.org.
howto/release/index.rst
howto/release/post-release/
howto/release/vcs/
---------------------------
o Document more release related activity (bugfix branch creation)
makefiles/consts.mk
-------------------
o Define and use more library macros.
config.mk
---------
o Per-repository library makefile configuration, disable linting.
makefiles/virtualenv.mk
-----------------------
o Library virtualenv install with dependences.
o Begin using a consistent install directory.
o Ugh: repository (voltha-docs) submodules each install a full venv.
o Install dependency drive based on existence of activate script.
o Lint targets updated to use activate script as a dependency.
o Update activate macro to run: set -u && activate && set +u
makefiles/patches/include.mk
----------------------------
o Update to use virtualenv.mk defined macros.
makefiles/lint/doc8.mk
makefiles/lint/python/flake8.mk
makefiles/lint/json.mk
makefiles/lint/python/pylint.mk
makefiles/lint/robot.mk
makefiles/lint/shell.mk
makefiles/lint/yaml.mk
-------------------------------
o All library linting defines consistent targets and logic.
o Support two library targets: lint-all and lint-modified.
o Default to checking all available sources.
o Linting can be disabled per-repository via {project}/config.mk
