[5.4] - post_max_size of 0 throws PostTooLargeException for POST requests of any size

[prurigro]

• Laravel Version: 5.4.5
• PHP Version: 7.0.10
• Database Driver & Version: N/A

Description:

Setting post_max_size to 0 should disable the post size limit, but getPostMaxSize in https://github.com/laravel/framework/blob/5.4/src/Illuminate/Foundation/Http/Middleware/ValidatePostSize.php treats it as a maximum post size of 0 bytes and throws the PostTooLargeException exception for POST requests of any size.

Steps To Reproduce:

Set post_max_size to 0 in php.ini and attempt to send a POST request to trigger this check (eg: log in using Laravel's native authentication)
