6be0ffd943 DataStreams/JSONEachRow: read exact number of rows 
When using a LIMIT to reduce the number of rows
read, JSONEachRow format would always read an
extra row as it triggered a scan to seek the
EOF or beginning of the next row. This is not
an issue with physical tables, but it is
for streaming tables as an extra row is
unintentionally consumed on each read.

5f53df7dbe ParserCreateQuery: allow ATTACH TABLE x shorthand statement 
Allow `ATTACH TABLE [db.]name` if the table was previously detached,
an the table structure can be read from disk. This makes reattaching
tables less cumbersome:

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

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.

e2a8526990 ZooKeeper: fixed stack smashing with tryGet() 
The tryGet() operation creates a 1MB buffer on stack. This may or
may not work depending on the default stack size for threads,
whether the stack protector is enabled or not, recursion depth,
and the actual value size.

This is probably going to slow down some ZK operations, but I don't
see how else this could work reliably with the existing API.

70543200be dbms: Fix build with clang after Poco update 
In the current version of Poco, unsigned long no longer aliases to
UInt64 with LP64. The size_t aliases to unsigned long with clang,
so all the uses of size_t instead of UInt64 when interacting with
Poco interfaces are gone. I replaced uses with UInt64 where it makes
sense, and added an overloaded function for readVarUInt() to support size_t.

2edf5492d0 AggregateFunctionSumMap: support variardic arguments, specialized keys 
The function is rewritten to avoid allocations on every insert with
Field deserialising each array. The key type is now specialized,
so it can be accessed directly. The value type is variant type,
but only individual values are deserialised (which is cheap, since they're PODs).
The function also support summing of multiple columns by the same key.

The SummingSortedBlockInputStream uses the function in case of
Nested structure with one numeric key and many values to sum.
