Update from 6.0.1 to 6.0.2.

<ChangeLog>

Upgrade urgency MODERATE: many not critical bugfixes in different areas.

Critical fix to client side caching when
keys are evicted from the tracking table but
no notifications are sent.

The following are the most serious fix:

• XPENDING should not update consumer's seen-time
• optimize memory usage of deferred replies - fixed
• Fix CRC64 initialization outside the Redis server itself.
• stringmatchlen() should not expect null terminated strings.
• Cluster nodes availability checks improved when there is high Pub/Sub load on the cluster bus.
• Redis Benchmark: Fix coredump because of double free
• Tracking: send eviction messages when evicting entries.
• rax.c updated from upstream antirez/rax.
• fix redis 6.0 not freeing closed connections during loading.

New features:

• Support setcpuaffinity on linux/bsd
• Client Side Caching: Add Tracking Prefix Number Stats in Server Info
• Add --user argument to redis-benchmark.c (ACL)
