useful anyway.

Fixed wait condition to wait for InnoDB to actually acquire row locks instead
of waiting for thread to enter "Searching rows for update" state (which happens
earlier).
Also use default wait timeout, 2 seconds can be too few for threads to enter
appropriate state.

Integer comparison of INT expressions with different signess in BETWEEN

The main.merge test case was failing when tested using row based
binlog format.
While analyzing the issue it was found the following issues:
a) The server is calling binlog related code even when a statement will
not be binlogged;
b) The child table list was not present into table structure by the time
to generate the create table statement;
c) The tables in the child table list will not be opened yet when
generating table create info using row based replication;
d) CREATE TABLE LIKE TEMP_TABLE does not preserve original table storage
engine when using row based replication;
This patch addressed all above issues.
@ sql/sql_class.h
Added a function to determine if the binary log is disabled to
the current session. This is related with issue (a) above.
@ sql/sql_table.cc
Added code to skip binary logging related code if the statement
will not be binlogged. This is related with issue (a) above.
Added code to add the children to the query list of the table that
will have its CREATE TABLE generated. This is related with issue (b)
above.
Added code to force the storage engine to be generated into the
CREATE TABLE. This is related with issue (d) above.
@ storage/myisammrg/ha_myisammrg.cc
Added a test to skip a table getting info about a child table if the
child table is not opened. This is related to issue (c) above.

CONSTRAINT.
Analysis
=======
INSERT and UPDATE operations using the IGNORE keyword which
causes FOREIGN KEY constraint violations reports an error
despite using the IGNORE keyword.
Foreign key violation errors were not ignored and reported
as errors instead of warnings even when IGNORE was set.
Fix
===
Added code to ignore the foreign key violation errors and
report them as warnings when the IGNORE keyword is used.

ITEM_PARAM::SAFE_CHARSET_CONVERTER
ISSUE:
------
Charset conversion on a null parameter is not handled
correctly.
SOLUTION:
---------
Item_param's charset converter does not handle the case
where it might have to deal with a null value. This is
fine for other charset converters since the value is not
supplied to them at runtime.
The fix is to check if the parameter is now set to null and
return an Item_null object. Also, there is no need to
initialize Item_param's cnvitem in the constructor to a
string. This can be done in
ITEM_PARAM::SAFE_CHARSET_CONVERTER itself.
Members of Item_param, cnvbuf and cnvstr, have been removed
and cnvitem has been made a local variable in
ITEM_PARAM::SAFE_CHARSET_CONVERTER.

'SYSTEM LOCK' IN PROCESSLIST
Analysis
=========
Show processlist shows 'System Lock' in 'State' field while
LOAD DATA INFILE is running.
thd->proc_info update is missing in LOAD DATA INFILE path.
Thus any request will get last unpdated status from lock_table()
during open_table().
Fix:
=======
Update state information from LOAD DATA INFILE path.

Post-push fix: The problem was that condition variable
timeouts could in some cases (slow machines and/or short
timeouts) be infinite.
When the number of milliseconds to wait is computed, the
end time is computed before the now() time. This can result
in the now() time being later than the end time, leading to
negative timeout. Which after conversion to unsigned becomes
~infinite.
This patch fixes the problem by explicitly checking if we
get negative timeout and then using 0 if this is the case.

GENERATED BY THE EXP() FUNCTION
When generating the error message for numeric overflow, pass a flag to
Item::print() that prevents it from expanding constant expressions and
parameters to the values they evaluate to.
For consistency, also pass the flag to Item::print() when
Item_func_spatial_collection::fix_length_and_dec() generates an error
message. It doesn't make any difference at the moment, since constant
expressions haven't been evaluated yet when this function is called.

we can see from the hang stacktrace, srv_monitor_thread is blocked
when getting log_sys::mutex, so that sync_arr_wake_threads_if_sema_free
cannot get a change to break the mutex deadlock.
The fix is simply removing any mutex wait in srv_monitor_thread.

Don't read from socket in yassl in SSL_pending().
Just return size of the buffered processed data.
This is what OpenSSL is documented to do too:
SSL_pending() returns the number of bytes which have been processed,
buffered and are available inside ssl for immediate read.

For some reason check_cxx_compiler_flag() passes result variable name down to
compiler:
https://github.com/Kitware/CMake/blob/master/Modules/CheckCXXSourceCompiles.cmake#L57
But compiler doesn't permit dashes in macro name, like in
-DHAVE_CXX_-fimplicit-templates.
Workarounded by renaming HAVE_CXX_-fimplicit-templates to
HAVE_CXX_IMPLICIT_TEMPLAES.
