* fix segfault on ATTACH MATERIALIZED VIEW
* allow only TEMPORARY TABLEs (not databases or views)
* forbid choosing ENGINE for TEMPORARY tables
* fix segfault on CREATE TABLE t1 AS t2 where t2 is a View
Previously the destination columns were only computed for the first
block, so that subsequently written blocks failed to write
aggregation results to corrent columns.
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.
This fixes a variant of SummingMergeTree() in which
the columns to sum are explicitly configured.
Previously columns not in that list were ignored,
instead of writing last value.
This also fixes summation of invalid maps with
with only one key column and no value columns.
Modified test to work around compaction limitation
in which a zero-value column isn’t compacted
immediately if the inputs are non-zero but the
output is zero (+1 -1).

* 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.
* increased timeout for test_insertion_sync_fails_with_timeout

* Dont strip debug info from asan, tsan and other builds except releases
* Fix asan error causd by test 00144
* Fix empty log message (#CLICKHOUSE-3378)
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.
