Comment (by ericlewis):

 Had a [https://wordpress.slack.com/archives/core/p1456175527000853 good
 chat with @boonebgorges] about the demerits of
 [https://core.trac.wordpress.org/ticket/22249#comment:22 refactoring our
 script loader to use an array hash].

 In attachment:22249.3.diff

 * Instead of changing `$in_footer` to an array hash, add a sixth argument
 for element attributes. Placing a script in the footer seems like a
 separate responsibility to think about when writing code.
 * Create separate methods on `WP_Scripts` for `get_script_attributes()`
 and `get_concatenated_script_attributes()`.
 * Add tests.

 Do we still want to offer a filter for script attributes now that its
 available on the register/enqueue functions?
