* make a local variable for target_table->field[col]
* move an often-used bit function to my_bit.h
* remove a non-static and not really needed trivial comparison
  function with a very generic name

The filter command did not accept characters . [ ] which are valid
in an attribute name for a sphinx query with json filtering.

+ test case added

BLES (in CREATE_OPTIONS column)

MDEV-9833 - fix mysql_config --libs for weird cases, where mysqlclient link dependencies contain  flags instead of libraries (like  -pthread rather than -lpthread)

Restoring currect_select fixed.

Adjusted INSTALL_LIBDIR detection so that it is set to "lib64" on any 64bit
system (not only x86_64). New condition is insipired by GNUInstallDirs cmake
module.

MDEV-9559: Server without encryption configs crashes if selecting from an implicitly encrypted table

There was two problems. Firstly, if page in ibuf is encrypted but
decrypt failed we should not allow InnoDB to start because
this means that system tablespace is encrypted and not usable.
Secondly, if page decrypt is detected we should return false
from buf_page_decrypt_after_read.

MDEV-9557 - fix compilation errors due to missing krb5_free_unparsed_name() in old versions of Heimdal Kerberos

Patch originally by Codarren Velvindron

Revert the patch for MDEV-9504.
It causes test failures, attempt to fix these causes more failures. The
source of all this is that the code in test_if_skip_sort_order() has
a peculiar way of treating select_limit parameter:
Correct value is computed when the query plan is changed. In other cases,
we use an approximation that ignores the presence of GROUP BY clause,
or JOINs, or both.

A patch that fixes all of the above would be too big to do in 10.1

The memory loss could happen in Aria with encrypted tables when Aria failed to encrypt a block.
In normal usage this should never happen.

create_partition_index_description() had wrong logic to calculate
length of the key value buffer that is used by the range optimizer.

For some reason it used MAX(partitioning_columns_len,
subpartitioning_columns_len) while it should use SUM of these values.

- Legacy code would set JOIN_TAB::limit only for EXPLAIN queries (this
  variable is only used when producing EXPLAIN output)

- ANALYZE/SHOW EXPLAIN need to produce EXPLAIN output for non-EXPLAIN
  queries, too, so we should always set JOIN_TAB::limit.

The check for UCONTEXT in cmake was somehow become broken, disabling the
fallback to ucontext. This caused the non-blocking client API to not be
available for non-x86 platforms, on which no hand-crafted assembler
implementation of my_context is available.

DBUG_ASSERT() added in the patch for MDEV-9181 did not take into account
special circumstances for the prepared statement EXECUTE. Fixig the assert.
Also, extending and fixing comments made during MDEV-9181.

The test restarts the server, it should not be executed for embedded

Don't assert if decrypt or encrypt fails if my_assert_on_error is not set.
Added failed file name if encryption/decryption fails.

Wrapping args[0] and args[2] into an Item_cache for aggregate functions.

        The SQL command 'PREPARE' was broken - should be take into
        account.

        Keep the embedded-server version valid.

        SHOW CREATE PROCEDURE/FUNCTION fixed.

        SHOW BINARY LOGS fixed.

        SHOW MASTER STATUS fixed.

        SHOW SLAVE STATUS fixed.
