Load the pyproject.toml file. Parameters: use_pep517 - Has the user requested PEP 517 processing? None means the user hasn't explicitly specified. pyproject_toml - Location of the project's pyproject.toml file setup_py - Location of the project's setup.py file req_name - The name of the requirement we're processing (for error reporting) Returns: None if we should use the legacy code path, otherwise a tuple ( requirements from pyproject.toml, name of PEP 517 backend, requirements we should check are installed after setting up the build environment )

Parse multiple statements into a list until one of the end tokens is reached. This is used to parse the body of statements as it also parses template data if appropriate. The parser checks first if the current token is a colon and skips it if there is one. Then it checks for the block end and parses until if one of the `end_tokens` is reached. Per default the active token in the stream at the end of the call is the matched end token. If this is not wanted `drop_needle` can be set to `True` and the end token is removed.
