lib/{mergeset,storage}: do not cache inverted index blocks containing tag->metricIDs items
...
This should reduce the amounts of used RAM during queries with filters over big number of time series.

lib/storage: create and use lib/uint64set instead of map[uint64]struct{}
...
This should improve inverted index search performance for filters matching big number of time series,
since `lib/uint64set.Set` is faster than `map[uint64]struct{}` for both `Add` and `Has` calls.
See the corresponding benchmarks in `lib/uint64set`.

lib/{storage,mergeset}: verify PrepareBlock callback results

Do not touch the first and the last item passed to PrepareBlock
in order to preserve sort order of mergeset blocks.

lib/storage: generate the first tag->metricIDs item in a mergeset block with a single metricID
...
The first item from each mergeset block goes into index (lib/mergeset.blockHeader),
so it must be short in order to reduce index size.

lib/{storage,mergeset}: merge tag->metricID rows into tag->metricIDs rows for common tag values
...
This should improve lookup performance if the same `label=value` pair exists
in big number of time series.
This should also reduce memory usage for mergeset data cache, since `tag->metricIDs` rows
occupy less space than the original `tag->metricID` rows.

lib/storage: optimize selecting all the metricIDs by scanning MetricID->TSID entries instead of tag->MetricID entries
...
The number of MetricID->TSID entries is smaller than the number of tag->MetricID entries
and MetricID->TSID entries are usually shorter than tag->MetricID entries.
This should improve performance when selecting all the metricIDs.
