2d2e738085 Add CRC32IEEE()/CRC64() support
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()

c2fa7ffcd3 Drop note about "estimation error for large sets will be large"
Since error is not that large, especially for uniqCombined64():

rows     error     uniqCombined64()/rows

- 1e8    0.00096   (0.99903523)
- 2e8    0.50200   (1.005022735)

f46c5a47c0 Introduce uniqCombined64() to get sane results for cardinality > UINT_MAX
By default uniqCombined() uses 32-bit hash for all types except String,
so this means that you cannot use uniqCombined() with i.e UInt64 and
cardinality > UINT_MAX, although you can use uniqCombined(toString())
and this will lead to 64-bit hash, but will not have good performance.

So uniqCombined64() had been introduced to fix this.
