Introducing `ZendParamMode` to as a idl flag. We are not consistent with zend on how they do their params for builtins. We cast to the expected data type. They do some checks, and if the checks don't pass they issue a warning and return (usually) `null`. This diff starts us down that path. I'm introducing the param and using it in the places where we were emulating the calling convention in the `f_foo` functions. I'm going to follow up with converting as many as I can and then eventually this becomes the default. I also want this to be applied to php files in systemlib. Many of the conversions are from https://github.com/php/php-src/blob/master/Zend/zend_API.c#L305
HipHop VM for PHP 
HipHop VM (HHVM) is a new open-source virtual machine designed for executing programs written in PHP. HHVM uses a just-in-time compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. HipHop VM (and before it HPHPc) has realized > 5x increase in throughput for Facebook compared with Zend PHP 5.2.
HipHop is most commonly run as a standalone server, replacing both Apache and modphp.
Installing
You can install a prebuilt package or compile from source.
Running
You can run standalone programs just by passing them to hhvm: hhvm my_script.php.
HipHop bundles in a webserver. So if you want to run on port 80 in the current directory:
sudo hhvm -m server
For anything more complicated, you'll want to make a config.hdf and run sudo hhvm -m server -c config.hdf.
Contributing
We'd love to have your help in making HipHop better. If you run into problems, please open an issue, or better yet, fork us and send a pull request. Join us on #hhvm on freenode.
If you want to help but don't know where to start, try fixing some of the Zend tests that don't pass. You can run them with hphp/test/run. When they work, move them to zend/good and send a pull request.
