Implementation of rows-in-block
- Fixes some things missed in myisam->maria port - Moved variables that holds the state for the current row to 'cur_row' - Changed most uchar * to byte * to be able to remove a lot of casts - Removed RAID support - Added CHECK for rows-in-block - Added allocate_dynamic() for easier usage of dynamic rows when we know how many entries we will need - Reorder columns after CREATE for more optimal row storage (for rows-in-block) - Removed flag 'RRND_PRESERVER_LASTINX' (not needed) - Extended ma_test_all.sh to test more completely all row formats - New structs and variables to hold rows-in-block and bitmap information - Added org_data_file_type in header to allow easy restore of old record format when doing maria_pack / maria_chk -u - More virtual functions to handle different row types - Pointer to row is now MARIA_RECORD_POS instead of my_off_t - New header signature for MARIA index files - Fixed bugs in ma_test1.c and ma_test2.c - All key and row blocks are now of same size - We now only have one link chain for deleted key blocks include/m_string.h: Define bzero_if_purify include/maria.h: Implementation of rows-in-block include/my_base.h: Implementation of rows-in-block include/my_handler.h: Cleanup macros Added size_to_store_key_length() include/my_sys.h: Added 'allocate_dynamic()' include/myisamchk.h: Implementation of rows-in-block mysys/array.c: Added allocate_dynamic() mysys/mf_keycache.c: Moved DBUG_ENTER to it's right position mysys/my_pread.c: Ensure my_errno is always set sql/filesort.cc: Fixed some compiler warnings sql/gen_lex_hash.cc: Removed not needed 'inline' sql/ha_maria.cc: Implementation of rows-in-block Fixed compiler warnings sql/mysqld.cc: Fixed setting of wrong variable sql/uniques.cc: Fixed compiler warnings storage/maria/Makefile.am: Implementation of rows-in-block storage/maria/ma_check.c: Removed RAID functions Added support for CHECK of rows-in-blocks rows storage/maria/ma_checksum.c: Implementation of rows-in-block storage/maria/ma_close.c: Implementation of rows-in-block storage/maria/ma_create.c: Implementation of rows-in-block: -

New structs and variables to hold rows-in-block and bitmap information - Added org_data_file_type in header to allow easy restore of old record format when doing maria_pack / maria_chk -u - More virtual functions to handle different row types -
