e2eac858b5 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.

947decb3dd lib/storage: remove outdated comment on maxRowsPerSmallPart
The commend became outdated after the commit ed6ac1a5df027f0dfc22448e3b27c26b6f77c67a,
which stops merging of small parts on graceful shutdown instead of waiting
for their completion.

8c2158af24 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.

4fb635b0c9 lib/storage: do not change timestamps to constant rate if values are constant or have constant delta
This breaks the original timestamps, which results in issues like
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/120 and
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/141 .

97b5dc7122 lib/encoding/zstd: disable CRC checks in pure Go build

3fae34eeb4 lib/encoding: improve gauge series detection
- Series with negative values are always gauges
- Counters may only have increasing values with possible counter resets

This should improve compression ratio for gauge series which
were previously mistakenly detected as counters.
