    Will in future changeset (soon) av versioning of status variables (number of rows) and index
    Changed some LEX_STRING to LEX_CUSTRING to avoid casts and warnings
    Removed some not needed variables (as noticed by Guilhem)
    
    
    include/maria.h:
      Added prototypes for maria_chk_init_for_check(), maria_versioning() and maria_ignore_trids()
    include/my_base.h:
      Add new error HA_ERR_ROW_NOT_VISIBLE
    include/myisamchk.h:
      Added variables for checking visibility of rows during maria_chk
    include/thr_lock.h:
      Changed argument type from int to my_bool for get_status
      Added variable allow_multiple_concurrent_insert, to signal if table supports multiple concurrent inserts
    mysql-test/r/maria-page-checksum.result:
      Added missing drop table
    mysql-test/t/maria-page-checksum.test:
      Added missing drop table
    mysys/my_handler.c:
      Added new error messages
    mysys/thr_lock.c:
      Added support for multiple concurrent inserts, if table handler supports it
    sql/sql_yacc.yy:
      Added LOCK TABLE table_name WRITE CONCURRENT
      This was added (temporarly?) to be able to check versioning with Maria
    storage/csv/ha_tina.cc:
      Updated parameter for get_status
    storage/maria/ha_maria.cc:
      Added calls to maria_chk_init_status()
      Fixed call to ma_control_file_open()
    storage/maria/ma_blockrec.c:
      Changed some LEX_STRING to LEX_CUSTRING to avoid casts and warnings
      Changed back some 'header' parameters to const char*
      Removed some casts
      
      Added support for versioning:
      - If info->row_flag & ROW_FLAG_TRANSID is set, store transaction id together with the row
      - When reading rows, check if rows are visible. Give error if not
      - When scanning table, ignore not visible rows
      - Added function parameters to some functions, to be able to call _ma_compact_block_page() with different parameters depending of if the page is a HEAD or TAIL page
      - _ma_compact_block_page() deletes transaction id's that are visible by all running transactions
      - Added functions for thr_lock() to enable multiple concurrent inserts
      - Added helper function 'mysql_versioning()' to enable/disable versioning
      - Added helper function maria_ignore_trids(), used by maria_chk and maria_pack to see all rows.
    storage/maria/ma_blockrec.h:
      Updated parameters for some functions.
      Added new functions to read/store state with thr_lock
    storage/maria/ma_check.c:
      Enable handling of transaction id's in rows
      Give a readable error if a table contains a transation id that makes rows not visible
    storage/maria/ma_control_file.c:
      Added option to not give warning if control file doesn't exists.
    storage/maria/ma_control_file.h:
      Updated parameter lists for ma_control_file_open()
    storage/maria/ma_delete.c:
      Removed not used variable (suggestion by Guilhem)
    storage/maria/ma_locking.c:
      Changed type of argument from int -> my_bool
    storage/maria/ma_open.c:
      Removed not used variables 'key_write_undo_lsn' and 'key_delete_undo_lsn'
      Added new thr_lock interface functions for BLOCK_RECORD to enable multiple concurrent insert
    storage/maria/ma_test1.c:
      Added option --versioning (-C) to check versioning
    storage/maria/ma_test2.c:
      Added option -C to check versioning
    storage/maria/ma_test_recovery:
      Forward argumetns to ma_test_recovery.pl
    storage/maria/ma_write.c:
      Removed not used variable key_write_undo_lsn
    storage/maria/maria_chk.c:
      Always read control file (if exist) at start
      Initialize checking of tables by calling maria_chk_init_for_check()
      In verbose mode and in case of error, print max found transaction id
    storage/maria/maria_def.h:
      Added Trid to MARIA_ROW to be able to check transaction id for found row
      Moved 'base_length' from MARIA_ROW to MARIA_HA to be able to handle different base length (with and without TRANSID) without if's
      Added default row_flag to MARIA_HA for the same reason
      Changed LEX_STRING -> LEX_CUSTRING to avoid casts in ma_blockrec.c
      Removed not needed variables key_write_undo_lsn and key_delete_undo_lsn
      Added prototypes for new functions and fixed those that had changed
    storage/maria/maria_pack.c:
      Ensure we can read all rows from the file, independent of the used transaction id
    storage/maria/maria_read_log.c:
      Updated arguments to ma_control_file_open()
    storage/maria/trnman.c:

      Fixed that trnman_can_read_from() returns that row is readable if it was written by current transaction
