Removed 'galera-sst-mode' option from mysqldump and added logic
in wsrep_sst_mysqldump script to retrieve gtid_binlog_state from
donor node and send it to the joiner node.
partially cherry-pick from mysql/5.6.
No test case (mysql/5.6 test case is useless, the correct
test case uses too much memory)

Problem: For every event read, mysqlbinlog calls localtime() which in turn
calls stat(/etc/localtime) which is causing kernel mutex contention.
Analysis and Fix:
localtime() calls stat(/etc/localtime) for every instance of the call
where as localtime_r() the reentrant version was optimized to store
the read only tz internal structure. Hence it will not call
stat(/etc/localtime). It will call only once at the beginning.
The mysql server is calling localtime_r() and mysqlbinlog tool is
one place where we are still using localtime().
Once the process (mysqlbinlog) is started if timezone is changed
it will be not picked up the the process and it will continue
with the same values as the beginning of the process. This
behavior is in-lined with mysql server.
Also adding localtime_r() and gmtime_r() support for windows.

mysqlimport had code for multi-threaded import. By mistake it was disabled for
many years, at least since 5.5 (more likely even in 5.1), but mysqlimport happily
accepted (and ignored) --use-threads option ever since.
After Mroonga merge HAVE_LIBPTHREAD became defined and multi-threaded import
suddenly came to life. As it exit() the program brutally on any error (never mind
that some import threads may be running) mysys rightfully complains. Safemalloc
complains too in debug builds.
Fix: don't try a clean exit on an error, don't shutdown mysys and tell safemalloc
to shut up. Yes, and remove #ifdef HAVE_LIBPTHREAD, since 5.5 the client library
is always multi-threaded.
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.
This patch fixes so that we always include my_global.h or my_config.h before we include any other files.
Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
"always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

The problem was that my_hash_sort didn't properly delete end-space characters properly, so strings that should compare
identically was seen as different strings. (Space was handled correctly, but not NBSP)
This caused duplicate key errors when a heap table was converted to Aria as part of overflow in group by.
Fixed by removing all characters that compares as end space when creating a hash.
Other things:
- Fixed that --sorted_results also works for errors in mysqltest.
- Speed up hash by not comparing strings that has different hash.
- Speed up many my_hash_sort functions by using registers to calculate hash instead of pointers.
This was previously done for some functions, but not for all.
- Made a macro of the hash function, to simplify code and to be able to experiment with new hash functions.

Description: Sometimes when killing the mysql command line client with
KILL -2(SIGINT), mysql client core dumps as a result of a double free or
corruption.
Analysis: When we run the mysql client in command line mode it will goes
to mysql_end() and frees many data structures. At the same time (i.e
after some data structures are freed), if we give "KILL -2" signal then
the signal will be handled with function handle_kill_signal() and as
part of it will again calls mysql_end() and goes with free() to the
already freed data structure for batch_readline_end() function, which
causes core dump.
Fix: Ignoring SIGQUIT and SIGINT signals when cleanup process starts.
This will help in resolving the double free issues, which occurs
in case the signal handler function is started in between of the
clean up function.
For 5.6 we need to ignore SIGHUP also.

A new command line option "galera-sst-mode" was introduced
in mysqldump as part of fix for MDEV-6316. But, since the
fix was pushed to maria-10.0-galera branch, the mysqldump
tool supplied with mariadb client deb/rpm packages, does not
have this new opion.
This fix contains the same patch along with a test case.
main.mysqlslap fail on PPC64
There seem to be a bug on Power8 which doesn't guarantee
a signal to be delivered to waiting thread if broadcast
is called outside of mutex.
For now workaround it by calling broadcast while mutex is
still held.
Mysqldump overflows stack buffer when copying table name from commandline arguments resulting in stack corruption and ability to execute arbitrary code.
Fix: Check length of all positional arguments passed to mysqldump is smaller than NAME_LEN.
Note: Mysqldump heavily depends on that database objects (databases, tablespaces, tables, etc) are limited to small size (now it is 64).

MDEV-6344: mysqldump issues FLUSH TABLES, which gets written into binlog and replicated
Add a --gtid option (for compatibility, the original behaviour is preserved
when --gtid is not used).
With --gtid, --master-data and --dump-slave output the GTID position (the
old-style file/offset position is still output, but commented out). Also, a
CHANGE MASTER TO master_use_gtid=slave_pos is output to ensure a provisioned
slave is configured in GTID, as requested.
Without --gtid, the GTID position is still output, if available, but commented
out.
Also fix MDEV-6344, to avoid FLUSH TABLES getting into the binlog. Otherwise a
mysqldump on a slave server will silently inject a GTID which does not exist
on the master, which is highly undesirable.
Also fix an incorrect error handling around obtaining binlog position with
--master-data (was probably unlikely to trigger in most cases).
MySQL 5.6 implemented WL#344, which is about a MASTER_DELAY option to CHANGE
MASTER. But as part of this worklog, the format of the realy-log.info file was
changed. The new format is not understood by earlier versions, and nor by
MariaDB 10.0, so changing server to those versions would cause the slave to
abort with an error due to reading incorrect data out of relay-log.info.
Fix this by backporting from the WL#344 patch just the code that understands
the new relay-log.info format. We still write out the old format, and none of
the MASTER_DELAY feature is backported with this commit.
The bug was in the mysqltest.c. It didn't check the send_query result
properly, so when that fails and the thread gets disconnected,
it goes unnoticed, so the consequitive read_result call crashes.
Fixed by checking the sernd_query return.
MYSQLADMIN IN PROCESSES LIST
Description: Checking the process status (with ps -ef)
while executing "mysqladmin" with old password and new
password via command-line will show the new password in the
process list sporadically.
Analysis: The old password is being masked by "mysqladmin".
So masking the new password in the similar manner would
reduce hitting the bug. But this would not completely fix
the bug, because if "ps -ef " command hits the mysqladmin
before it masks the passwords it will show both the old and
new passwords in the process list. But the chances of
hitting this is very less.
Fix: The new password also masked in the similar manner
that of the --password argument.

- let table cache use pre-calculated MDL hash value
- MDL namespace is excluded from hash value calculation, so that
hash value can be used by table cache as is
- hash value for MDL is calculated as resulting hash value + MDL
namespace
- extended hash implementation to accept user defined hash function
- MariaDB-5.5 part of the fix: since we can't easily fix query optimization for I_S tables,
run the affected-tablespaces query with semijoin=off. It happens to have a good query plan
with that setting.
[This is a forward-port to MariaDB 10.0]
mysqltest in the 'embedded-server' mode runs queries in a separate thread,
but it didn't do so for the prepared statements - they were run in the main thread.
That leads to inconsistencies.
When a test sets SESSION 'dbug' variable like
SET SESSION debug_dbug="+d,warn_during_ha_commit_trans";
it is run as a plain query in that separate thread, so the main thread remains unaffected.
After that the prepared statement run in the main thread doesn't produce expected 'dbug' errors,
so the test fails.
To fix that I made prepared statement to be run in that special thread along with the plain queries.
That makes the environment consistent.
This is port of fix for MySQL BUG#17647863.

Rename test() macro to MY_TEST() to avoid conflict with libc++.

along with query buffer.
The problem was uncovered by udf_debug_sync.test when it was run with
--embedded.

Problem: While printing the Server version, mysql client
doesn't check for the buffer overflow in a
String variable.
Solution: Used a different print function which checks the
allocated length before writing into the string.

When running with multi-source enabled master (MariaDB 10.0) all master will be recorded
mysql-test/r/rpl_mysqldump_slave.result:
Updated results to new syntax
MDEV-4984: Implement MASTER_GTID_WAIT() and @@LAST_GTID.
MDEV-4726: Race in mysql-test/suite/rpl/t/rpl_gtid_stop_start.test
MDEV-5636: Deadlock in RESET MASTER
MASTER_GTID_WAIT() is similar to MASTER_POS_WAIT(), but works with a
GTID position rather than an old-style filename/offset.
@@LAST_GTID gives the GTID assigned to the last transaction written
into the binlog.
Together, the two can be used by applications to obtain the GTID of
an update on the master, and then do a MASTER_GTID_WAIT() for that
position on any read slave where it is important to get results that
are caught up with the master at least to the point of the update.
The implementation of MASTER_GTID_WAIT() is implemented in a way
that tries to minimise the performance impact on the SQL threads,
even in the presense of many waiters on single GTID positions (as
from @@LAST_GTID).

But when tool forks "mysqlcheck"/"mysql", "--no-defaults" is passed
as first argument. Before forking, in function "find_tool" of
"mysql_upgrade", check is made to verify whether tool can be
executable or not by calling "mysqlcheck --help" and "mysql --help".
But argument "--no-defaults", "--defaults-file" or
"defaults-extra-file" is not passed to "mysql" and "mysqlcheck".
So my.cnf is searched in default paths.
Fix:
------
Modified code to pass "--no-defaults" as first argument to "mysql"
and "mysqlcheck" while checking tool can be executed or not.
