Avoid calling ResStatisticsStatement::start if stats is disabled.

If repository statistics is disabled then start() and related should

not be called. Improvement in YCSB's OPS and AvgResp_ms were noticed

with this change.

Address LP 1404951 - seabase/TEST010 failing

This commit changes the default value for COMP_BOOL_184 to 'ON'.

The effect of this is that MDAM probes will now fetch only one row

of data rather than the previous default of 100 rows.

NOTE: Because the original problem reported in LP 1404951 does not

seem to be reproducible any more, this check-in is being made to

improve the performance of MDAM problems.

HOWEVER, it is possible that this change will cause the original

problem to occur again. Namely that an incorrect number of rows

could be returned for certain SQL queries (as originally reported

in LP 1404951.) If anyone does run into this problem again, the

default value for COMP_BOOL_184 will need to be changed back to

'OFF' until the root cause for the incorrect number of rows issue

can be determined.

New ustat algorithm and bulk load integration

This is the initial phase of the Update Statistics change to use

counting Bloom filters and a Hive backing sample table created

during bulk load and amended whenever a new HFile for a table

is created. All changes are currently disabled pending some

Fix diff of TEST042

Compile Time in EXPECTED042 are 00:00:00.001742 and 00:00:00.001621,

which are considered FAIL by FILTER042, while result in offical build

are within SUCCESS range.

It is tricky that you have to update EXPECT042 with LOG042 from release build.

Support cancel for DDL, update stats, and utils

This change propagates parent query ID to queries created

by DDL, update stats and utils. In this way, preexisting

code sets up child query IDs and the preexisting cancel

broker code in RMS cancels the entire query tree below

the indicated parent. Also added is logic to check for a

canceled parent at the time a child query ID is setup in

Statement::execute, to make the scheme more robust and

to support a common scenario where the parent is compiling

a child query at the time of cancel.

This change also makes ex_root_tcb::cancel to wait for

cancel broker message completion. This fixes a problem where

a query (e.g., CREATE INDEX or DROP INDEX) is prepared,

executed once and gets an error, then re-execed. In this

case, sqlci was not closing the statement after the error.

To improve robustness, after an error we will now wait for

message completion, if needed.

Since we do not yet have transaction protection for DDL,

it will usually be required to cleanup canceled DDL

operations by using the CLEANUP command.
