mm: memcontrol: make tree_{stat,events} fetch all stats
Currently, tree_{stat,events} helpers can only get one stat index at a time, so when there are a lot of stats to be reported one has to call it over and over again (see memory_stat_show). This is neither effective, nor does it look good. Instead, let's make these helpers take a snapshot of all available counters.
