When passing an array from PHP to Lua, stringify integer array keys
beyond the range a lua_Number can represent.
When passing a table from Lua to PHP,
* Avoid exponential encoding for integer keys beyond 1e14, so Zend PHP
will interpret them as integers.
* Always encode integer keys as integers, so HHVM will interpret them as
integers.
* Detect collisions, e.g. { [0] = 'foo', ["0"] = 'bar' }

The extraneous whitespace in the return value from wfShellExec() causes
multiplying $size to trigger the newly introduced "A non well formed
numeric value encountered" warning in PHP 7.1+.
Work around that by using trim() to get rid of the whitespace.

The two lualib/ustring generation scripts run independently of MediaWiki, so
the new wfIsCLI() isn't usable there.
