Fix part of bug #9670: if MySQL calls ::store_lock with TL_IGNORE, do not change prebuilt->select_lock_type; this fix may heal the assertion failures reported in UPDATE and multi-table UPDATE; it is not clear if this fixes the problems in OPTIMIZE TABLE

                causes system crash.

  At the shutdown, write the latest lsn only to the first pages of the ibdata files of the system tablespace, NOT to the .ibd files; writing to tens of thousands .ibd files can take minutes

  Fix the patch of Jan to optimize next-key locking in searches of type 'primary key >= some value'

into hundin.mysql.fi:/home/heikki/mysql-4.1

  Do not test the value of err if the lock operation was skipped because innodb_logs_unsafe_for_binlog was TRUE; though this did not cause any bugs visible to the user, because err is inited to DB_SUCCESS at the start of the function row_search_for_mysql()

not produce phantom (bug #9354).

  Add some more dump

 - If number of records in table is 4, the calculated cost for using "index" and "range" become so close so that any rounding errors becomes visible.
 - Added one more record to the tables for heap test and expoect "range" to be selected
 - Decrease number of records in t1 for range and expect "index" to be choosen.
