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: calculate the maximum number of rows per small part from -memory.allowedPercent
...
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/159
This simplifies error detection additionally to the `vm_rows_ignored_total` counters.

all: use workingsetcache instead of fastcache
...
This should reduce the amount of RAM required for processing time series
with non-zero churn rate.
The previous cache behavior can be restored with `-cache.oldBehavior` command-line flag.
