The --enable_prepare_warnings allows to not discard warnings from autorepair
of crashed table in --ps-protocol mode.

Use this to properly fix the parts.partition_recover_myisam and
maria.maria-recover tests.

Add a test case for the new feature. This also adds missing test coverage
for the case where the same warning is thrown in both prepare and execute
phase.


client/mysqltest.cc:
  Implement new commands --enable-prepare_warnings and --disable_prepare_warnings.
mysql-test/r/mysqltest_ps.result:
  Add test case for new --enable_prepare_warning mysqltest command.

- Include maria_chk and other maria binaries
- Include sql/$TARGET/mysqld.lib, like mainline does (but what is that useful for?)
- Don't include my_safe_{process,kill} garbage.
- call '/bin/find', not just 'find' is that is some incompatible windows command.

 - Don't need any m1 prefix for the first release based on given MySQL
   version number.

 - Fix mysql-test-run to understand that some stuff is installed under
   share/mariadb rather than share/mysql.

MBUG#442254: mysql-test-run --embedded fails on Windows with: ERROR: .opt file references 'EXAMPLE_PLUGIN_OPT'
- Fix suggested by Kristian on review: ignore the test using mtr's facilities

- Part 2. make it really work.

- Update EXPLAIN results after table elimination
- mysqlslap now specifies 'Engine=' in CREATE TABLE instead of using 
  SET storage_engine=...
- For some reason, mysqltest logs "connect" command differently when PBXT
  is the default storage engine. This is probably a bug in mysqltest which
  we can't be bothered to investigate at the moment, so add --replace

mysql-test/suite/pbxt/r/connect.result:
  Fix pbxt test suite failures:
  - For some reason, mysqltest logs "connect" command differently when PBXT

- Adjust CMakeLists.txt to follow latest mysql's expectations about plugins
- Add typecasts
- wrap pbms_enabled.cc in #ifdef

 - innodb-index needs regexp replace for embedded like other similar tests.

 - partitions_special_* need to be modified for the extension from 16 to 32
   max key parts allowed that was made in MariaDB.

When DNS is not working and returns some address even for non-existing
host names, some test cases fail with wrong error.

Fix by disabling these tests on such systems.

"Merge Monty's fixes from main into release branch" .. cset):
- mysql_get_server_name() is a new client API function and so should
  be exported from libmysql[d].

libmysql/libmysql.def:

libmysqld/libmysqld.def:

 - Don't omit the @@debug variable from testcase check, since it can cause real problems.
 - Fix some bad merges by reverting to be identical to MySQL 5.1.

storage/maria/ma_blockrec.c:
  GCC warns about const vs. non-const despite cast
  (but it is in any case cleaner to avoid the cast completely)
support-files/compiler_warnings.supp:
  Silence a wrong compiler warning caused by GCC bug.

  'innobase'.

Otherwise following tests go crazy in the log, writing gigabytes of data
and causing havoc.

- Don't run testcase for BUG#45632 with embedded server.

 - MariaDB naming.
 - Error reporting with mysqld --help --verbose.

mysql-test/r/mysqld_option_err.result:
  Test that mysqld --not-known-option --help --verbose gives error
mysql-test/t/mysqld_option_err.test:
  Test that mysqld --not-known-option --help --verbose gives error

- mysql_get_server_name()
  This returns MySQL or MariaDB depending on the server type
- mariadb_connection()
  This returns 1 if you are connected to a MariaDB server

Modifed the MySQL command line client to print out if you are connected to MariaDB or MySQL
Better default prompt (shows server you are connected to and base directory)

client/mysql.cc:
  Print out if you are connected to MariaDB or MySQL
  Better default prompt (shows server you are connected to and base directory)
  Added option \N to prompt to print server name.
configure.in:
  Changed maria to MariaDB in version string
include/mysql.h:
  Added mysql_get_server_name() and mariadb_connection()
include/mysql.h.pp:
  Update for new API functions
libmysql/libmysql.c:
  Added client functions:
  - mysql_get_server_name()
    This returns MySQL or MariaDB depending on the server type
  - mariadb_connection()
    This returns 1 if you are connected to a MariaDB server

to have to rely on fragile regexp-parsing of configure.in.

server, as it doesn't work there.

sql/sql_plugin.cc:
  Temporary solution: skip PBXT (like we do e.g. for --skip-innodb) in embedded server, as it doesn't work there.

This allows to eg use --mem or --parallel for better performance on big boxes.
