Summary: The mbstring extension is common but not part of the PHP core, and we have a soft dependency on it but generally guard calls with function_exists(). Add the mbstring functions to the whitelist of known extension functions so lint doesn't raise errors about them if you don't have mbstring installed.
Test Plan: @ffx, can you verify this fixes the lint issue for you? Probably faster than recompiling my PHP without mbstring.

Summary:
Spamming everyone who got bitten by this. We upgraded the libphutil library system recently, but the "use of undeclared function" lint check used to run only on files you touched and now runs on every file in every library you use. This means that if you don't have pcntl or ldap installed, you'll get errors about use of functions from them on every change.
Instead, ship with a list of functions which are provided by extensions that we'll ignore when calculating dependencies, so not having pcntl doesn't mean you have to excuse through irrelevant errrors every time.
Test Plan: Ran script with an unknown function, got it in the map; added it to the extension list, it vanished from the map.
