phan/phan 4.1.0

Release 4.1.0 supporting PHP 7.0-8.0 syntax

on GitHub

Maintenance:

• Recommend using Phan 5 when analyzing code (#4487)
• Mention that Phan 5 has been released in --help, --version, and crash reports (#4487)
  The environment variable PHAN_SUPPRESS_PHP_UPGRADE_NOTICE=1 can be set to disable this notice.
• Warn if attempting to execute Phan 4.x with PHP 8.1 (Phan 5 fully supports all PHP 8.1 features, notably intersection types)
• Upgrade from tolerant-php-parser 0.0.23 to 0.1.1
• Backport some changes from Phan 5 for php 8.1 first-class callable conversion (...) and avoid crashing when parsing intersection types.
  Note that Phan 5 must be used instead to actually support intersection types; intersection types are not part of Phan 4's type system.
