[VOL-5051] - Triage bbsim build
[VOL-5092] - verify_bbsim_unit-test repository failures in jenkins job history.
makefiles/*
-----------
o Merge in latest library makefiles.
o Some legacy retained:
tools.mk => makefiles/docker/include.mk
makefiles/lint/docker/*.mk (replace with docker/include.mk.new)
Makefile
--------
o Remove bogus foobar target.
o Target docs-lint now maps to library target lint-doc8.
docs/Makefile
-------------
o venv install now handled by makefiles/virtualenv.mk
o Replaced inlined doc8 lint target with makefiles/lint/doc8 (lint-doc8)
o Use std defines for SHELL= and other constants.
o Replace separator ';' with '&&' in commands using venv (detect errors).
config.mk
---------
o Enable lint targets for doc8, docker & json.
o More lint checks can be enabled but cleanup is needed first.
docs/Makefile
requirements.txt
----------------
o Identified a few python module problems documented in VOL-5092.
o Makefile wild target(%) matching stray dependencies so hardcode sphinx targets to act on.
o Added hyphen/success to "make docs" until VOL-5092 can be straightened out.
