The CSPRNG failing should be rare nowadays, but it *might* happen and without
this patch it's hard for the user to find out why the salt generation failed:
The error message is not actionable.
This patch will automatically set the CSPRNG exception to the `$previous`
exception of the ValueError that is thrown, allowing the developer to determine
the cause of the salt generation failure.
Before:
Fatal error: Uncaught ValueError: Unable to generate salt in php-src/test3.php:3
Stack trace:
#0 php-src/test3.php(3): password_hash(Object(SensitiveParameterValue), '2y')
#1 {main}
thrown in php-src/test3.php on line 3
After:
Fatal error: Uncaught Random\RandomException: Cannot open /dev/urandom: No such file or directory in php-src/test3.php:3
Stack trace:
#0 php-src/test3.php(3): password_hash(Object(SensitiveParameterValue), '2y')
#1 {main}
Next ValueError: Unable to generate salt in php-src/test3.php:3
Stack trace:
#0 php-src/test3.php(3): password_hash(Object(SensitiveParameterValue), '2y')
#1 {main}
thrown in php-src/test3.php on line 3
