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.

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
include/myisam.h:
Change type of myisam_block_size and myisam_concurrent_insert to make them changeable in mysqld.cc
Removed not used varaible myisam_max_extra_temp_length
include/thr_lock.h:
Added extra parameter to get_status
myisam/mi_create.c:

myisam/mi_dynrec.c:
If 'append_insert_at_end' is set, only write at end of myisam record file
myisam/mi_locking.c:
Add extra argument to 'mi_get_status' to allow thr_lock to signal that we want to do a concurrent insert
If this is used, we will append new insert rows at end of data file.
Change mi_check_status() to allow concurrent_inserts even if there are holes in the file when myisam_concurent_insert=2
myisam/mi_static.c:
Change behavior of myisam_concurrent_insert so that setting this to 2 allows inserts even if there is a hole in the data file.
Default value is 2 for MyISAM direct usage but will be set to 1 (old default) by mysqld.cc
myisam/mi_statrec.c:
If 'append_insert_at_end' is set, only write at end of myisam record file
myisam/mi_write.c:
If 'append_insert_at_end' is set, only write at end of myisam record file
myisam/myisamdef.h:
Support for insert-at-end even if there is holes in data file

* Make index merge quick selects code allow perform several scans.
* Delay additional handler objects creation till row retrieval is started.
include/queues.h:
Added trivial queue_remove_all macro
mysql-test/r/index_merge.result:
Testcase for BUG#4177
mysql-test/t/index_merge.test:
Testcase for BUG#4177
sql/opt_range.cc:
Fix for BUG#4177:
* For any quick select, row retrieval can be performed several times. Now all index_merge quick selects code handles such cases properly.
* In QUICK_INDEX_MERGE_SELECT we use one handler object for all merged scans, and it was possible that in
destructor several cleanup functions were called
* Additionally
- Removed redundant QUICK_INDEX_MERGE_SELECT members.
- Now QUICK_ROR_*_SELECTs create additional handler objects only when row retrieval is started
So if join optimizer chooses other access method, we don't create/delete handlers.
Note: One sp.test still fails (prime), and rpl_server_id2.test fails (will be fixed by guilhem ASAP).
