Don't allow imported IDs to be greater than 2^31 — at Initial Version

For various reasons, things go bad when you get a post ID greater than 231. When we're importing content and there's an existing ID, I suggest we ignore it if possible if it's too big.
Tumblr2WordPress for example maintains the Tumblr IDs and causes problems in WordPress.
