Summary:
Fixes T5545. We assume `strlen()` returns the number of bytes in a string, which is the normal behavior (and the documented behavior).
There's a config option, `mbstring.func_overload`, which silently calls mb_strlen() instead. This may return some other result, might fail, etc., and there's no way to get the byte length of a string if this option is set.
If this option is set, fatal immediately. Nothing good can ever come of it.

Summary: See IRC. This is dumb but I think we should try to work by default on Debian, and it doesn't cost us too much. See inline comment for more.
Test Plan:
- No `disable_functions`, restarted, worked fine.
- Set `disable_functions = pcntl_derp`, restarted, worked fine.
- Set `disable_functions = derp`, restarted, setup fatal.

Summary:
Fixes T3709. PHP has two configuration options ('disable_functions', 'disable_classes') which allow functions and classes to be blacklisted at runtime.
Since these break things in an unclear way, raise a setup fatal if they are set.
We take a slightly more tailored approach to these in `phd` already, but I'd rather try just saying "no, this is bad" and see if we can get away with it. I suspect we can, and there's no legitimate reason to blacklist functions given that Phabricator must have access to, e.g., `proc_open()`.
