f95b5b0a5d BUG#17314: Can't use index_merge/intersection for MERGE tables
1. Fix index access costs for MERGE tables, set block_size=myisam_block_size/#underlying_tables 
   instead of 0 which it was before.
2. Make index scans on MERGE table to return records in (key_tuple, merge_table_rowid) order, 
   instead of just (key_tuple) order. This makes an index scan on MERGE table to be truly a ROR-scan
   which is a requirement for index_merge union/intersection.

e40759e370 BUG#16166, "Can't use index_merge with FORCE INDEX": adjust the heurstics check to take into
account that "FORCE INDEX" disables full table scans, and not range/index_merge scans.

2d25da2a4b concurrent-insert can now be set to 2 for concurrent inserts when there is holes in the data file
myisam_max_extra_sort_file_size is depricated
Ensure that myisam_data_pointer_size is honoured when creating new MyISAM files
Changed default value of myisam_data_pointer_size from 4 to 6 to get rid of 'table-is-full' errors
