and support MySQL CMakeLists.txt files

mysql_upgrade --help now also prints out --default options and variable values.
mysql_upgrade now prints permission errors.

Added handler error message about incompatible versions
Fixed that mysqlbug and mysql_install_db have the executable flag set.
Removed executable flag for some non executable files.
Changed in mysql_install_db askmonty.org to mariadb.com.
Ensured that all client executables prints --default options the same way.
Allow REPAIR ... USE_FRM for old .frm files if the are still compatible.
Extended shown error for storage engine messages.

- When a JOIN has both "optimization tabs" (JOIN_TABs used to 
  read the base tables and do the join operation) and also
  has "execution tabs" (a JOIN_TAB that is to produce result set 
  that is sent to the client), do not forget to call JOIN_TAB::cleanup()
  for the execution JOIN_TAB.

update_used_tables() should be called after handling derived tables in any case.

Don't writing entries to slave log about binlog_checksum not existing on master if log_warnings is <=1.

This solves the issue of getting a lot of unnecessary errors logged on the slave when connecting to MySQL or an old MariaDB version.


sql/slave.cc:
  Don't write that binlog_checksum doesn't exists on the master if log_warnings <= 1

This only happend when using an ORDER BY on a primary key part, where all other key parts where constant.
Remove of duplicated expressions in ORDER BY (as the old code did this in some strange cases)


mysql-test/r/group_by.result:
  Fixed results to take into account that duplicate order by parts are now deleted
mysql-test/r/group_by_innodb.result:
  Ensure extended keys are on
mysql-test/r/innodb_ext_key.result:
  More tests
mysql-test/r/order_by.result:

mysql-test/t/group_by.test:
  Fixed results to take into account that duplicate order by parts are now deleted

sql/sql_select.cc:
  Fixed bug where we looked at extended key parts when we shouldn't
  Remove of duplicated expressions in ORDER BY
sql/table.cc:
  Indentation fixes

- Add --sorted_result to the query

Materialization forced in case if rand() used in view or derived table to avoud several calls of rand for gting value of a field.

Fixed set variable uncachable flag from - it shouldbe a side effect not a random value.

Fix EXPLAIN and CREATE SELECT to join_free() (and, thus, ha_index_end())
before ha_commit_trans().

Fixed a wrong assertion.

This test needs at least 320M for tokudb-max-lock-memory.
Normally tokudb-max-lock-memory is auto-sized to be 1/16th
of the available RAM size, and many our test VMs have 4G of RAM.

The fix for bug #27937 was incomplete: it did not handle correctly the queries
containing UNION with global ORDER BY in subselects.

(better to have an address in the output than ??:0)

(PLUGIN_VAR_MEMALLOC is 0x8000 and cannot be saved in a char as such)"

don't reset interrupted_query after sending the KILL signal, otherwise
the client won't know it has to stop fetching and printing the data.

a memory leak in save_index() first seen in the test case for mdev-5382.

When marking used columns the function find_field_in_table_ref() erroneously
called the walk method for the real item behind a view/derived table field
with the second parameter set to TRUE.
This erroneous code was introduced in 2006. 

Correct processing of view/derived with no tables added.

"Conditional jump or move depends on uninitialised"
in Item_time_typecast::get_date.

Adding "null_value" into the debug assert condition.

Fix ha_myisammrg::update_create_info() to do what ha_myisammrg::append_create_info() does -
take sub-table names from TABLE_LIST, not reverse engineer tablefile names.

Backport praveenkumar.hulakund@oracle.com-20120127081643-u7dxy23i8yyqarm7 from mysql-5.6
