Changed format for REDO_INSERT_ROWS_BLOBS
Fixed several bugs in handling of big blobs
Added redo_free_head_or_tail() & redo_insert_row_blobs()
Added uuid to control file
maria_checks now verifies that not used part of bitmap is 0
REDO_PURGE_BLOCKS -> REDO_FREE_BLOCKS
Added REDO_FREE_HEAD_OR_TAIL
Fixes problem when trying to read block outside of file during REDO


include/my_global.h:
  STACK_DIRECTION is already set by configure
mysql-test/r/maria.result:
  Updated results
mysql-test/t/maria.test:
  Test shrinking of VARCHAR
mysys/my_realloc.c:
  Fixed indentation
mysys/safemalloc.c:
  Fixed indentation
sql/filesort.cc:
  Removed some casts
sql/mysqld.cc:
  Added missing setting of myisam_stats_method_str
sql/uniques.cc:
  Removed some casts
storage/maria/ma_bitmap.c:
  Added printing of bitmap (for debugging)
  Renamed _ma_print_bitmap() -> _ma_print_bitmap_changes()
  Added _ma_set_full_page_bits()
  Fixed bug in ma_bitmap_find_new_place() (affecting updates) when using big files
storage/maria/ma_blockrec.c:
  Changed format for REDO_INSERT_ROWS_BLOBS
  Fixed several bugs in handling of big blobs
  Added code to fix some cases where redo when using blobs didn't produce idenital .MAD files as normal usage
  REDO_FREE_ROW_BLOCKS doesn't anymore change pages; We only mark things free in bitmap
  Remove TAIL and filler extents from REDO_FREE_BLOCKS log entry. (Fixed some asserts)
  REDO_PURGE_BLOCKS -> REDO_FREE_BLOCKS
  Delete tails in update. (Fixed bug when doing update that shrinks blob/varchar length)
  Fixed bug when doing insert in block outside of file size.
  Added redo_free_head_or_tail() & redo_insert_row_blobs()
  Added pagecache_unlock_by_link() when read fails.
  Much more comments, DBUG and ASSERT entries
storage/maria/ma_blockrec.h:
  Prototypes of new functions
  Define of SUB_RANGE_SIZE & BLOCK_FILLER_SIZE
storage/maria/ma_check.c:
  Verify that not used part of bitmap is 0
storage/maria/ma_control_file.c:
  Added uuid to control file
storage/maria/ma_loghandler.c:
  REDO_PURGE_BLOCKS -> REDO_FREE_BLOCKS
  Added REDO_FREE_HEAD_OR_TAIL
storage/maria/ma_loghandler.h:
  REDO_PURGE_BLOCKS -> REDO_FREE_BLOCKS
  Added REDO_FREE_HEAD_OR_TAIL
storage/maria/ma_pagecache.c:
  If we write full block, remove error flag for block.
  (Fixes problem when trying to read block outside of file)
storage/maria/ma_recovery.c:
  REDO_PURGE_BLOCKS -> REDO_FREE_BLOCKS
  Added REDO_FREE_HEAD_OR_TAIL
storage/maria/ma_test1.c:
  Allow option after 'b' to be compatible with ma_test2
  (This is just to simplify test scripts like ma_test_recovery)
storage/maria/ma_test2.c:
  Default size of blob is now 1000 instead of 1
storage/maria/ma_test_all.sh:
  Added test for bigger blobs
storage/maria/ma_test_recovery.expected:
  Updated results
storage/maria/ma_test_recovery:
  Added test for bigger blobs
