Summary:
Fixes T5377. The current `scripts/update_compat_info.php` script works for PHP CompatInfo version 2, but doesn't work with the newer version 3.
There are a few breaking changes in version 3 that had to be addressed:
- PHP 5.3 is required. Whilst Arcanist is generally compatible with PHP 5.2, I don't think that having this dependency presents any real issues because it is purely a development tool that is rarely updated.
- [[https://getcomposer.org/ | Composer]] is used for packaging, which makes including the library slightly more complicated. Basically, I had to install `PHP_CompatInfo` globally with Composer (`composer global require "bartlett/php-compatinfo"` and then symlink `~/.composer/vendor` into `externals/includes`.
Test Plan: Compared the `resources/php_compat_info.json` file. There are a bunch of functions/classes that //were// in this file but are no longer, but I think that I've covered the most popular extensions.

Summary: Ref T5141. In order to be able to warn when deprecated functions are used, we need to be aware of from which version the functions were deprecated.
Test Plan: Ran `arc lint` and made sure no unexpected warnings were raised.

Summary: Ref T5141. Currently, `php_compat_info.json` is hardcoded to support PHP 5.2.3. Instead, store as much version information as possible in `php_compat_info.json` and filter accordingly in `ArcanistXHPASTLinter.`
Test Plan: Ran `arc lint` and made sure no additional warnings were raised.
