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



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:
  Ensure that myisam_data_pointer_size is honoured
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
