This patch makes several scripts and PHP development tools files executable and adds more proper shebangs to the PHP scripts. The `#!/usr/bin/env php` shebang provides running the script via `./script.php` and uses env to find PHP script location on the system. At the same time it still provides running the script with a user defined PHP location using `php script.php`.
Generic hashing framework for PHP
Simplest usages:
$digest = hash($algoname, $message);
$digest = hash_file($algoname, $filename);
Examples:
$digest = hash('md5', 'The quick brown fox jumped over the lazy dog.');
Feeder usage:
$context = hash_init($algoname);
hash_update($context, $message);
$digest = hash_final($context);
hash(), hash_file(), and hash_final() each support an optional boolean parameter $raw_output which behaves in the same
manner as sha1()'s optional parameter.
