Bootloader build

• Fix build for FreeBSD (#2861, #2862).

PyInstaller Core

• Usage: Add help-message clarifying use of options when a spec-file is
  provided (#3039).

  • Keep order of imported identifiers.

Test-suite and Continuous Integration

• In Continuous Integration tests: Enable flake8-diff linting. This will
  refuse all changed lines not following PEP 8.

• Enable parallel testing on Windows,

• Update requirements.

• Add more test cases for modulegraph.

• Fix a test-case for order of module import.

• Add test-cases to check scripts do not share the same global vars (see below).

Documentation

• Add clarification about treatment of options when a spec-file is provided
  (#3039).

• Add docs for running PyInstaller with Python optimizations (#2905).

• Add notes about limitations of Cython support.

• Add information how to handle undetected ctypes libraries.

• Add notes about requirements and restrictions of SWIG support.

• Add note to clarify what binary files are.

• Add a Development Guide.

• Extend "How to Contribute".

• Add "Running the Test Suite".

• Remove badges from the Readme (#2853).

• Update outdated sections in man-pages and other enhancements to the
  man-page.

Known Issues

• All scripts frozen into the package, as well as all run-time hooks, share
  the same global variables. This issue exists since v3.2 but was discovered
  only lately, see #3037. This may lead to leaking global variables
  from run-time hooks into the script and from one script to subsequent ones.
  It should have effects in rare cases only, though.
