9963e2f160 Fix uniqHLL12 and uniqCombined for cardinalities 100M+. 
* Changing size() return type from UInt32 to UInt64 to prevent overflow (this shouldn't break back compatibility).
 * Removing "big cardinalities fix" for cardinalities >2^32/30 as it was very inaccurate and for estimates >2^32 it was trying to do 'log' of negative number which is NaN and it was casted to 0.
 * Adding python script to show that intHash32 is not a good choice for HyperLogLog algorithm when it's used for linear counting branch of it.
 * Adding bash script to test uniq, uniqHLL12, uniqCombined on different set cardinalities.
 * Altering documentation of uniq* aggregate functions with recommendations to use uniq instead of uniqHLL12 or uniqCombined.

c6e959d1e9 StorageKafka: extended configuration, parallel consumers, offset tracking 
This contains many fixes and corrections for the Kafka engine.
Most notably it now supports extended configuration similarly to GraphiteMergeTree.
Now it also allows specification of consumer count to parallelize consumption of
multiple partitions both in materialized views and in SELECT queries.

The offsets are now committed in the insertSuffix() method after all rows
are successfully read. If an exception is thrown during reading, affected consumer
unsubscribes from all assignments and rejoins the consumer group to rewind offsets.
This means that the consumer won't lose messages in case of write failures.

0d942a69c5 DataStreams: added Cap’n Proto format support 
Cap'n Proto is a binary message format.
Like Protocol Buffers and Thrift (but unlike JSON or MessagePack), Cap'n Proto messages are strongly-typed and not self-describing. Due to this, it requires a schema setting to specify schema file and the root object. The schema is parsed on runtime and cached for each SQL statement.

e936c4d066 AggregateFunctionSum: implemented sumWithOverflow(x) 
By default sum(x) promotes the result type to
largest possible integral type to avoid
arithmetic overflow when summing values from
smaller data types.

This is generally desirable behaviour, but it doesn’t
work with summing merge tree, as the result is
expected to be of same type as the input.

Allow `ATTACH TABLE [db.]name` if the table was previously detached,

CREATE TABLE test.t (x UInt8) ENGINE = Null;

975a7ada42 StorageMaterializedView: allow CREATE MATERIALIZED VIEW x TO y 
This allows creation of materialized views without inner tables,
using an existing table for materialized rows instead.
This is useful for cases when you want to detach the materializing
view, but keep the already materialized data readable, especially
when the inner table is replicated.
