Remove null hint from MainLogger::getLogger() so static analysis doesn't complain everywhere
just make sure you register the logger before trying to use MainLogger::getLogger() on a different thread!
All plugins will need to bump the API if they want to use this.
NOTE THAT THIS IS NOT THE FINAL API 2.0.0 AND THAT THERE WILL BE MORE CHANGES.
To start updating, you might also want to read https://secure.php.net/manual/en/migration70.php and specifically https://secure.php.net/manual/en/migration70.incompatible.php
To compile PHP7 with some of the required dependencies, use https://gist.github.com/shoghicp/166ab26ce5cc7a390f45
ONLY LINUX IS TESTED, DO NOT ASK FOR OTHER PLATFORMS!
----- THIS VERSION IS NOT SUPPORTED -----
This version WILL crash randomly in unexpected places due to PHP7, pthreads, PocketMine or cosmic rays.
Handle with care, and store under direct sunlight for the best performance.
