lib/storage: stop background merge when storage enters read-only mode

This should prevent from `no space left on device` errors when VictoriaMetrics
under-estimates the additional disk space needed for background merge.

lib/storage: postpone reading data from blocks during search
...
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.
This improves single-node VM performance on heavy queries by up to 2x.

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`.
