Bug#30031130: MYSQL SERVER SEGFAULTS AT

STD::CONDITION_VARIABLE::WAIT_FOR IN SOLARIS/X86

When a MySQL Server built with ndbcluster engine is run in a
Solaris/x86 platform, it crashes everytime when
NDB_SCHEMA_OBJECT::client_wait_completed() method is called. The
segfault happens when this method calls the
std::condition_variable::wait_for() method. This particular crash
happens only in the release builds. The reason seems to be an issue with
the compiler used in Solaris. When the optimization level -xO2 is used,
it fills the wait_for() call with a bogus code that triggers this
segfault during runtime.

Fixed the issue by making the release builds use optimization
level -xO1 for ndbcluster instead.

Bug#29904751: LIKE CONDITION FOR DATE COLUMN RETURNS ERROR

Item_func_like inherits resolve_type from Item_bool_func2 but does not
have much in common with it's parent since every comparison must be done
as strings. Also the call to set_cmp_func() is unnecesary and results in
an error when comparing temporal types with strings.
This patch fixes this error by overriding resolve_type in
Item_func_like, and by omitting the call to set_cmp_func.

Bug#29705858 RUN_NDBAPITEST.INC ALWAYS EXIT TEST CASE WHEN THE NDBAPI…

…TEST SUCCEED

Exec_print_on_error() is used to run any executable in the system and upon
success run_ndbapitest.inc forcefully exits the test cases. This prevents the
execution of MTR framework function check_testcase(), which is run at the end
of every test case to check that the state of the database is same before
and after running the test.

Fix by removing the exit() function when exec_print_on_error() is success.

WL#13246 MODIFY TESTSCAN TO SUPPORT MIXED-VERSIONS. Post push fix.

Use Unsigned columns instead of signed Int columns for T18.

HugoCalculator assumes at least two unsigned columns to work.

And in testBackup runDDL() randomly choose a NDBT_Table and uses
HugoCalculator functionality on that.
