Added function to check for diff and return an error message if the utility is not present.
Previously, the way we did this didn't work on Windows, but did work on *Nix systems.
Execution of queries containing the CASE function of
aggregate function like in "SELECT ... CASE ARGV(...) WHEN ..."
crashed the server.
The CASE function caches pointers to concrete comparison
functions for an each pair of types of CASE-WHERE clause
parameters, i.e. for the "CASE INT_RESULT WHERE REAL_RESULT
THEN ... WHERE DECIMAL_RESULT ... END" function call it
caches comparisons for INT_RESULT with REAL_RESULT and
for INT_RESULT with DECIMAL_RESULT. Usually a result
type is known after a call to the fix_fields function,
however, the setup_copy_fields function call may
wrap aggregate items with Item_copy_string that has
STRING_RESULT result type, so setup_copy_fields may
change argument result types of the CASE function after
call to Item_func_case::fix_fields/fix_length_and_dec.
Then the Item_func_case::find_item function tries to
use comparison function for unexpected pair of the
STRING_RESULT and some other type - that caused
an assertion failure of server crash.
The Item_func_case::fix_length_and_dec function has
been modified to take into account possible STRING_RESULT
result type in the presence of aggregate arguments of
the CASE function.

Problem: When an Incident_log_event contains a bad incident number on disk,

Incident numbers should be hard-coded, since they may appear in files.

Problem was an errornous date that lead to end partition
was before the start, leading to a crash.
Solution was to check greater or equal instead of only
equal between start and end partition.
NOTE: partitioning pruning handles incorrect dates
differently than index lookup, which can give different
results in a partitioned table versus a non partitioned
table for queries having 'bad' dates in the where clause.

There can be cases where the start/cur partition is greater
than the end partition, so it must not continue, since that
can lead to a crash.
Table could be marked dependent because it is
either 1) an inner table of an outer join, or 2) it is a part of
STRAIGHT_JOIN. In case of STRAIGHT_JOIN table->maybe_null should not
be assigned. The fix is to set st_table::maybe_null to 'true' only
for those tables which are used in outer join.

The problem is that we cannot insert new record into memory table
when table size exceeds max memory table size.
The fix is to use schema_table_store_record() function which
converts memory table into MyISAM in case of table size exceeding.
Note:
There is no test case for this bug, the reason is that
1. The code that was added already is checked(i.e. works) with existing tests
2. Correct work of schema_table_store_record() is checked with other test cases
(information_schema tests)
So new code is fully covered with existing test cases.

- QUICK_INDEX_MERGE_SELECT deinitializes its rnd_pos() scan when it reaches EOF, but we
need to make the deinitialization in QUICK_INDEX_MERGE_SELECT destructor also. This is because
certain execution strategies can stop scanning without reaching EOF, then then try to do a full
table scan on this table. Failure to deinitialize caused the full scan to use (already empty)
table->sort and produce zero records.

resolve_stack_dump is not able to decode a stack trace produced
by glibc's backtrace() functions. The problem is that the stack
trace addresses are printed between brackets and the utility is
not able to ignore the brackets.
The solution is to modify resolve_stack_dump so it can recognize
stack trace addresses surrounded by brackets. e.g. [0xdeadbeef].
extra/resolve_stack_dump.c:
Skip to after a bracket if one is present in the input.
compiled --with-debug, due to bug 39828, "autoinc wraps around when offset and
increment > 1". This change should be reverted when that bug is fixed (and a
a few other minor changes to the test as described in comments).
