MDEV-33308 CHECK TABLE is modifying .frm file even if --read-only
As noted in commit d0ef1aaf61,
MySQL as well as older versions of MariaDB server would during
ALTER TABLE ... IMPORT TABLESPACE write bogus values to the
PAGE_MAX_TRX_ID field to pages of the clustered index, instead of
letting that field remain 0.
In commit 8777458a6e this field
was repurposed for PAGE_ROOT_AUTO_INC in the clustered index root page.
To avoid trouble when upgrading from MySQL or older versions of MariaDB,
we will try to detect and correct bogus values of PAGE_ROOT_AUTO_INC
when opening a table for the first time from the SQL layer.
btr_read_autoinc_with_fallback(): Add the parameters to mysql_version,max
to indicate the TABLE_SHARE::mysql_version of the .frm file and the
maximum value allowed for the type of the AUTO_INCREMENT column.
In case the table was originally created in MySQL or an older version of
MariaDB, read also the maximum value of the AUTO_INCREMENT column from
the table and reset the PAGE_ROOT_AUTO_INC if it is above the limit.
dict_table_t::get_index(const dict_col_t &) const: Find an index that
starts with the specified column.
ha_innobase::check_for_upgrade(): Return HA_ADMIN_FAILED if InnoDB
needs upgrading but is in read-only mode. In this way, the call to
update_frm_version() will be skipped.
row_import_autoinc(): Adjust the AUTO_INCREMENT column at the end of
ALTER TABLE...IMPORT TABLESPACE. This refinement was suggested by
Debarun Banerjee.
The changes outside InnoDB were developed by Michael 'Monty' Widenius:
Added print_check_msg() service for easy reporting of check/repair messages
in ENGINE=Aria and ENGINE=InnoDB.
Fixed that CHECK TABLE do not update the .frm file under --read-only.
Added 'handler_flags' to HA_CHECK_OPT as a way for storage engines to
store state from handler::check_for_upgrade().

bzip2/lz4/lzma/lzo/snappy compression is now provided via *services*
they're almost like normal services, but in include/providers/
and they're supposed to provide exactly the same interface
as original compression libraries (but not everything,
only enough of if for the code to compile).
the services are implemented via dummy functions that return
corresponding error values (LZMA_PROG_ERROR, LZO_E_INTERNAL_ERROR, etc).
the actual compression libraries are linked into corresponding
provider plugins. Providers are daemon plugins that when loaded
replace service pointers to point to actual compression functions.
That is, run-time dependency on compression libraries is now on plugins,
and the server doesn't need any compression libraries to run, but
will automatically support the compression when a plugin is loaded.
InnoDB and Mroonga use compression plugins now. RocksDB doesn't,
because it comes with standalone utility binaries that cannot
load plugins.
This commit is based on the work of Michal Schorm, rebased on the
earliest MariaDB version.

Identical key derivation code in XtraDB/InnoDB/Aria
* Extract it into the "encryption_scheme" service.
* Make these engines to use the service, remove duplicate code.
* Change MY_AES_xxx error codes, to return them safely
from encryption_scheme_encrypt/decrypt without conflicting
with ENCRYPTION_SCHEME_KEY_INVALID error
file_logger became the service.
Data like query_id now are sent to the audit plugin.
Fix for MDEV-4770 ported from 10.0.
Fix added for the read_maria_plugin_info().
Log rotation can be disabled with 'set rotations=0'.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
MYSQL_TIME and my_time_t and back.
Using the new service instead of direct access to thd.

modified for MySQL 5.5. Logger service moved to the
plugin/sql_errlog directory to be properly used later.
plugin/sql_errlog/sql_errlog.c:
Fixes for bugs #956427 (SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value) and #956463 (Server crashes if SQL_ERROR_LOG fails to initialize) they're also MDEV-184 and MDEV-183
The sql_error_log_deinit() should be prepared for the logger_file to be NULL.
The logger_file_size_limit upper limit wasn't properly set.
Added the logger service that provides us with the rotating logs.
The plugin SQL_ERROR_LOG added. It logs the errors using the 'logger service'
for the rotating log files.
the example record from the log:
2012-03-09 15:07:29 root[root] @ localhost [] ERROR 1146: Table 'test.xyz' doesn't exist : select * from test.xyz
it is a static library that links with shared libraries, so strictly speaking it should
have -fPIC or equivalent flags. Also, it must always build as static no matter
whether BUILD_SHARED_LIBS is set.
