Fixes lp:805930 Sysbench breaks on multiple table test with MariaDB 5.2.7 + Aria

Browse Source 
The bug happens when one uses MAX_ROWS=# with Aria & row_format=page and one insert more than # rows.


mysql-test/mysql-test-run.pl:
  Ignore table is full error messages
mysql-test/suite/maria/r/max_length.result:
  Test case for 'Table is full'
mysql-test/suite/maria/t/max_length.test:
  Test case for 'Table is full'
storage/maria/ma_bitmap.c:
  Ensure that we don't allocate bits outside of max_data_file_size.
  Adjust max_data_file_size based on bitmap alignments.
  Backport fix to adjust wrong first_bitmap_with_space.
storage/maria/ma_blockrec.c:
  Calculate value of max_data_file_length
storage/maria/ma_blockrec.h:
  Updated prototype for _ma_bitmap_init()
storage/maria/ma_check.c:
  Give warnings if file sizes are above max file sizes.
  Give more warnings in case of errors.
  Have maria_chk write if table is recreated.
storage/maria/ma_create.c:
  Better calculation of max_data_file_length and thus data pointer length.
  Fixes some wrong pointer lengths when using MAX_ROWS=#
storage/maria/ma_open.c:
  Removed duplicate assigment.
  Use block size from file instead of global variable.
storage/maria/maria_chk.c:
  Remove -1 from printed file length
storage/maria/maria_def.h:
  Update struct st_maria_file_bitmap
