- If one specifies --force twice to myisamchk and aria_chk, then we will try to finnish the repair even if sort_buffer would be too small.
  This was done by dynamically allocate buffer handler objects as long as memory lasts.
- New option for myisamchk and aria_chk: create-missing-keys
- Changed default size of myisam_sort_buffer_size from 8M to 128M.
- Changed default size of sort_buffer_size in aria_chk from 128M to 256M.
- Increased information in error message about 'sort_buffer_size' beeing to small.
- Print also to 'show warnings' if repair was retried.
- Increased size of internal sort-buffer-readers from 16K to 128K
- Changed printing of 'number of records' to use %ll instead of casting to long
- Changed buffer sizes for myisam and aria to use MY_ALIGN_DOWN() to get same number of bytes allocated on different machines.

mysql-test/t/myisam.test:
  Fixed error messages to not print system specific data
mysql-test/t/repair.test:
  Fixed error messages to not print system specific data
storage/maria/ha_maria.cc:
  Print also to 'show warnings' if repair was retried
  Changed default size of sort_buffer_size from 128M to 256M (same as in mysqld)
storage/maria/ma_check.c:
  Renamed USE_BUFFER_INIT -> PAGE_BUFFER_INIT
storage/maria/ma_sort.c:
  Increased size of internal sort-buffer-readers from 16K to 128K
  Increased size of types to be able to handle more records
  Added support for T_FORCE_SORT_MEMORY
  Don't allocate too many extra BUFFPEK at a time (they are probably not needed)
  Improved error message for "sort_buffer_size is too small"
  Changed printing of 'number of records' to use %ll instead of casting to long
  Fixed bug where maria_update_key_parts() was called too early.
  Fixed bug in detecting result from read_to_buffer().
  Added 'out of memory' checking when calling 'alloc_dynamic()'.
storage/maria/maria_chk.c:
  Added --create-missing-keys
  If one specifies --force twice then we will try to finnish the repair even if sort_buffer would be too small.
  check_param.sort_buffer_length varialble was used with wrong type.
storage/maria/maria_def.h:
  Increased size of types to be able to handle more records
  Use MY_ALIGN_DOWN() to get same number of bytes allocated on different machines
  Renamed USE_BUFFER_INIT -> PAGE_BUFFER_INIT
storage/maria/maria_ftdump.c:
  Renamed USE_BUFFER_INIT -> PAGE_BUFFER_INIT
storage/maria/maria_read_log.c:
  Use PAGE_BUFFER_INIT for page cache

  Renamed USE_BUFFER_INIT -> KEY_BUFFER_INIT
storage/myisam/myisam_ftdump.c:
  Renamed USE_BUFFER_INIT -> KEY_BUFFER_INIT
storage/myisam/myisamchk.c:
  Added --create-missing-keys
  If one specifies --force twice then we will try to finnish the repair even if sort_buffer would be too small.
  check_param.sort_buffer_length varialble was used with wrong type.
  Renamed USE_BUFFER_INIT -> KEY_BUFFER_INIT
storage/myisam/myisamdef.h:
  Increased SORT_BUFFER_INIT to 64M
  (speeds up repair a lot and most machines have nowadays a lot of memory)
  Use MY_ALIGN_DOWN() to get same number of bytes allocated on different machines
  Renamed USE_BUFFER_INIT -> KEY_BUFFER_INIT
storage/myisam/sort.c:
  Increased size of internal sort-buffer-readers from 16K to 128K
