Remove wp_parse_post_content(), get_paged_content(), paginate_content() from 3.6, and remove the new $id parameters for get_the_content() and the_content().

The content parsing functions are good abstractions, but are no longer needed by core and are too closely tied to legacy globals, rather than paving a new path.

For get_the_content() and the_content(), this only worsens the function prototype. It muddies theme-specific display (more links, etc) with filtered content. `apply_filters( 'the_content', $post->post_content )` is sufficient practice for now.
