Summary: Just like we ship with a list of extension functions, add a list of extension classes so people stop getting lint errors about DOMDocument just because some linter uses it.
Test Plan: Ran "arc lint".

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.

Summary:
Currently, when a file has a syntax error and you run "arc liberate", the symbol analyzer will fail and throw, which will make the mapper fail and throw, which will make arc fail and throw. This gives you a stack trace pile three scripts deep which is a giant pain to analyze visually.
Instead, raise a clear message.
Test Plan: Ran "arc liberate" with a syntax error. Got useful diagnostic output instead of 30 pages of stack mess.

Summary:
For `PhutilSymbolLoader` queries which include `setAncestorClass()`, we need the map of which classes/interfaces things extend/implement to issue the query efficiently.
Without this map, we need to load //every// class/interface and then do `is_subclass_of()`. This is doable, but not very performant if we don't have php-fpm warmup. There are a few performance-sensitive interfaces where we run queries like this, including some in Arcanist, where we'll never have warmup.
This map isn't particularly difficult to generate or maintain, so just include it in symbol generation and in the library map.
Also set parallelism with a flag, since it was arbitrarily hard-coded and adding flags is easy. 8 actually seems approximately optimal on my machine at least, though.
Test Plan: Ran "phutil_rebuild_map.php", opened library map, got a reasonable extension map.
