Remove parsing of output_file from configuration files as it was not consistently applied (See also GitLab!361)
Resolve configuration files relative to cwd instead of common prefix of passed filenames. You may need to change flake8 subproject to cd subproject && flake8 . (See also GitLab!363)

--disable-noqa now also disables # flake8: noqa (See also GitLab!380, GitLab#590)

Only enable multiprocessing when the method is fork fixing issues on macos with python3.8+ (See also GitLab!366, GitLab#587) (note: this fix also landed in 3.7.9)
noqa is now only handled by flake8 fixing specific-noqa. Plugins requesting this parameter will always receive False (See also GitLab!331, GitLab#552)
