Since background flush will not be accounted there, and it can be too
tricky to calclulate this limit, in case you have multiple materialized
views with Buffer engine.
v2: test adjustment
zlib's implementation uses CRC-32-IEEE 802.3 polynomial (0xedb88320) but
with starting value 0xffffffff, so introduce another crc32
implementation - CRC32IEEE that has starting value - 0
Also add CRC64 with ECMA polynomial.
v2: s/crc*_data./crc*_data./ to avoid conflicts with other crc32.h in contrib
v3: join with existing CRC32()
* Fix INSERT into Distributed non local node with MATERIALIZED columns
Previous patch e527def18a ("Fix INSERT
into Distributed() table with MATERIALIZED column") fixes it only for
cases when the node is local, i.e. direct insert.
This patch address the problem when the node is not local
(`is_local == false`), by erasing materialized columns on INSERT into
Distributed.
And this patch fixes two cases, depends on `insert_distributed_sync`
setting:
- `insert_distributed_sync=0`
```

* Cover INSERT into Distributed with MATERIALIZED columns and !is_local node
I guess that adding new cluster into server-test.xml is not required,
but it won't harm.
* Update DistributedBlockOutputStream.cpp
