Aliaksandr Valialkin 8aa9bba9bd lib/{mergeset,storage}: switch from sync.Pool to chan-based pool for inmemoryPart objects 
This should reduce memory usage on systems with big number of CPU cores,
since every inmemoryPart object occupies at least 64KB of memory and sync.Pool maintains
a separate pool inmemoryPart objects per each CPU core.

Though the new scheme for the pool worsens per-cpu cache locality, this should be amortized
by big sizes of inmemoryPart objects.
