rARCd477df00eb5b: Add a linter rule to detect the use of blacklisted functions
Summary

As mentioned in the Phabricator PHP coding standards, the eval function should be avoided. There is some good discussion on StackOverflow as well.

Having said that, instead of hardcoding eval(), I have generalised this enough to allow a set of "blacklisted" functions to be defined with xhpast.blacklisted.function in the .arclint file.

Test Plan

Added a test case.

Maybe we should implement this as xhpast.function-blacklist or similar (like phutil-xhpast.deprecated.functions), which would take a map from function name to explanation? That would be more flexible, at least. Not sure if there are other functions anyone might want to blacklist, though.

Seems reasonable.

Might be YAGNI but it's like 10 extra lines so this seems generally reasonable.
