Currently crypt data is written to file space always. Use
that to obtain random IV for every object (file).

Beatify code to confort InnoDB coding styles.

redo operations.

          for incorrect byte sequences

innodb_buffer_pool_pages_total depends on page size. On Power8 it is 65k
compared to 4k on Intel. As we round allocations on page size we may get
slightly more memory for buffer pool.

Sort XA RECOVER as rows order depend on endianness.

Installation scripts added to setup the required SP-s with the mysql_install_db.

Two problems:
- Read/Write outside of buffer at memcpy() because of incorrect parameters
. OPENSSL_assert(EVP_CIPHER_CTX_iv_length(&ctx.ctx) == iv_length); // ECB does not use IV, thus incorrect assertion

Added:
  mysql-test/include/encryption_algorithms.combinations to run tests with methods cbc, ecb and ctr in
  those systems where they are available (see suite.pm).

Removed pre-5.1 tweaks & logics from mysql_system_table_fix.sql.

This is an addition to original patch. Some platforms are strict about atomic
op argument signedness.

Spider support for new xid cache implementation.

XID cache is now based on lock-free hash.
Also fixed lf_hash_destroy() to call alloc destructor.

Note that previous implementation had race condition when thread was accessing
XA owned by different thread. This new implementation doesn't fix it either.

Missing .result file update.

Review fixes:
 - Coding style
 - Fix bad .result file
 - Fix test to be tolerant of different timing.
 - Fix test to give better info in case of unexpected timing.

Merge branch 'mdev-6981-master_gtid_wait-status-variables' of https://github.com/openquery/mariadb-server into danblack

Replaced all references to LINT_INIT with UNINIT_VAR and LINT_INIT_STRUCT.
Removed LINT_INIT macro.

suite.pm so that it is not used if not available.

to my_convert_fix() - a new function in /strings.

Checked for missing synonims, added those found.

Problem was that we considered the point itself as the 'border' object. Instead
of that the 'border' of a POINT is an empty set, and the point is the 'interior'.
Another error fixed by the way - not all operations of the resulting function were properly
allocated.

Need to take into account cases of a polygon shaped as a very thin line.

The variables now return real values. They can't be made usual variables because they do not have DEFAULT value.

Problem was in reinitialization of first_successful_insert_id_in_prev_stmt_for_binlog after setting variables.

Two problems:
- Read/Write outside of buffer at memcpy() because of incorrect parameters
. OPENSSL_assert(EVP_CIPHER_CTX_iv_length(&ctx.ctx) == iv_length); // ECB does not use IV, thus incorrect assertion

Added:
    mysql-test/include/have_file_key_management_plugin.combinations ( to run with aes_cbc and aes_ecb)
    mysql-test/include/have_openssl_ctr.combinations ( to run with aes_cbc, aes_ecb and aes_ctr)

The problem is in the IsSimple function. If the first and the last points
of a curve coincide it's and exception and the line is still 'simple'.
