Description: 

New function takes an array of node IDs and returns according timestamps or zero to bring history fetching down to one query for node teasers.
Also static cache name changed from history_read to history_read_multiple

background:
#1991684: Node history markers (comment & node "new" indicator, "x new comments" links) forces render caching to be per user forces render caching to be per user moves history fetching from being done once for each node in a teaser, to all at once (but currently in a separate HTTP request), this means looping over history_read() to get the timestamp for each nid.
