"mtr connect.odbc_postgresql"

The test has performance-schema in the opt file, so it failed when the server was compiled without performance schema.
Make the option loose, then MTR will be able to reach have_perfschema.inc check and will skip the test gracefully.

Problem was that test just takes too long time in slow I/O and triggers
testcase timeout. Reduced the number of operations and inserts to make
test shorter.

--gtid-ignore-duplicates was comparing sequence numbers as 32-bit, so
after 2**32 transactions things would start to fail.

Let mysqld_safe_syslog.cnf force disable error log so that logging to syslog is
not affected by previous log_error setting.

Added handling of --skip-log-error to mysqld_safe.

Merge error on srv0start.cc

Fixed small size limit and added additional information if we reserve
new pages more then 50 times.

Apply fixes for raw devices to XtraDB in MariaDB 10.0

- References changed from mysql.com to mariadb.com/kb
- NDB specfic things removed
- Changed other MySQL related things to MariaDB

Analysis; Problem is that InnoDB does not have support for generating
CURRENT_TIMESTAMP or constant default.

Fix: Add additional check if column has changed from NULL -> NOT NULL
and column default has changed. If this is is first column definition
whose SQL type is TIMESTAMP and it is defined as NOT NULL and
it has either constant default or function default we must use
"Copy" method for alter table.

The --gtid-ignore-duplicates option was not working correctly with row-based
replication. When a row event was completed, but before committing, there
was a small window where another multi-source SQL thread could wrongly try
to re-execute the same transaction, without properly ignoring the duplicate
GTID. This would lead to duplicate key error or out-of-order GTID error or
similar.

Thanks to Matt Neth for reporting this and giving an easy way to reproduce
the issue.

fix the test case for ps-protocol

MDEV-5977 MariaDB 10.0 is not installable on Trusty when "trusty-updates universe" is in sources.list

fix upgrade[2] tests on trusty and utopic: add missing
conflicts/replaces, client-10.0 should conflict/replace client-5.5.

reformat other conflicts/replaces lines to make them easier
to read and merge

in ha_delete_table()
* only convert ENOENT and HA_ERR_NO_SUCH_TABLE to warnings
* only return real error codes (that is, not ENOENT and
  not HA_ERR_NO_SUCH_TABLE)
* intercept HA_ERR_ROW_IS_REFERENCED to generate backward
  compatible ER_ROW_IS_REFERENCED

in mysql_rm_table_no_locks()
* no special code to handle HA_ERR_ROW_IS_REFERENCED
* no special code to handle ENOENT and HA_ERR_NO_SUCH_TABLE
* return multi-table error ER_BAD_TABLE_ERROR <table list> only
  when there were many errors, not when there were many
  tables to drop (but only one table generated an error)

in cmake tests let's treat clang like gcc (same options,
same builtins) in many cases.

* don't check the compiler when
  * testing for -fvisibility=hidden support
  * testing for HAVE_ABI_CXA_DEMANGLE
  * testing for HAVE_GCC_ATOMIC_BUILTINS
  * when removing options with string(replace)
  * when running ${CC} --version (ignore the error instead)
* run ABI checks for clang
* use "canonical" gcc flags for clang
* fix groonga too

Also:

* add cmake detection for gcc __atomic_* builtins. they might be
  supported (__ATOMIC_SEQ_CST is defined), but not for all operand
  sizes. In particular, 64-bit atomic load is problematic on i386
* cache check results for Windows
* remove the test for HAVE_CXXABI_H (HAVE_ABI_CXA_DEMANGLE is
  suffifient)

* new mysqldump option
* add more engines to the "external data engines" list
* redo the check to be able to print the list of engines in --help

in innobase: compilation error on windows
other changes: perfschema merge followup

only columns really stored to database.

When RENAME TABLE is executed, it apparently does not check whether the engine
is available (unlike ALTER TABLE .. RENAME, which does). It means that if the
engine in question was not loaded on some reason, the table might become
unusable, since the engine won't know about the change.

With this patch RENAME TABLE fails if storage engine is not available.

Put client plugins into -common rpm, not -shared.
Because they're needed for
* all clients that link with shared libmysqlclient (-shared)
* our clients from -client rpm, they're statically linked (-client)
* the server that acts as a replication slave (-server)

MDEV-7871 Tests fail massively on "Assertion `status_var.memory_used == 0'" when run with --ps --embedded.
   As the MF_THREAD_SPECIFIC was introduced to the alloc_root's and
   the prealloc added to the statement::mem_root and statement::result.alloc, we have to adjust
   the embedded server to it. The preallocation was removed for the embedded server as it
   makes no sence for it. The msyqltest should free the statement inside the proper thead to
   make the memory statistics happy.
