a86935a39b Allow ffi.metatype to fail so that "busted" unit tests work 
On Github we run unit tests inside "busted". At the start of each test "busted" does some sort of trick (clearing package.loaded)? Which causes "require" to run again for all lua files. This breaks ffi.metatype with error "cannot change a protected metatable" if it is called twice with a single type name, since this is true global state. To work around this this patch wraps ffi.metatype calls in a xpcall() so that failure is silently ignored.

94ef22b643 Fixed issues with ffi and cloning. 
Fixed the ffi check to now work correctly and moved the ffi local up a
scope so that it could be used later in the file. Made clone simply call
new().

Argh, struct redefinition errors. I'm glad that you can pcall this at
least.
