  branches/5.1: Since handler::get_auto_increment() doesn't allow us
  to return the cause of failure we have to inform MySQL using the
  sql_print_warning() function to return the cause for autoinc failure.
  Previously we simply printed the error code, this patch prints the
  text string representing the following two error codes:
  
  DB_LOCK_WAIT_TIMEOUT
  DB_DEADLOCK.
  
  Bug#35498 Cannot get table test/table1 auto-inccounter value in ::info
  
  Approved by Marko.

  Fix Bug#38231 Innodb crash in lock_reset_all_on_table() on TRUNCATE + LOCK / UNLOCK
  
  In TRUNCATE TABLE and discard tablespace: do not remove table-level S
  and X locks and do not assert on such locks not being wait locks.
  Leave such locks alone.

  branches/5.1:
  
  Fix Bug#39438 Testcase for Bug#39436 crashes on 5.1 in fil_space_get_latch
  
  In ha_innobase::info() - do not try to get the free space for a tablespace
  which has been discarded with ALTER TABLE ... DISCARD TABLESPACE or if the
  .ibd file is missing for some other reason.
  
  ibd_file_missing and tablespace_discarded are manipulated only in
  row_discard_tablespace_for_mysql() and in row_import_tablespace_for_mysql()
  and the manipulation is protected/surrounded by
  row_mysql_lock_data_dictionary()/row_mysql_unlock_data_dictionary() thus we
  do the same in ha_innobase::info() when checking the values of those members
  to avoid race conditions. I have tested the code-path with UNIV_DEBUG and
  UNIV_SYNC_DEBUG.
  
  Looks like it is not possible to avoid mysqld printing warnings in the
  mysql-test case and thus this test innodb_bug39438 must be added to the
  list of exceptional test cases that are allowed to print warnings. For this,
  the following patch must be applied to the mysql source tree:

  branches/5.1: This bug has always existed but was masked by other errors. The
  fix for bug# 38839 triggered this bug. When the offset and increment are > 1
  we need to calculate the next value taking into consideration the two
  variables. Previously we simply assumed they were 1 particularly offset was
  never used. MySQL does its own calculation and that's probably why it seemed
  to work in the past. We would return what we thought was the correct next
  value and then MySQL would recalculate the actual value from that and return
  it to the caller (e.g., handler::write_row()). Several new tests have been
  added that try and catch some edge cases. The tests exposed a wrap around
  error in MySQL next value calculation which was filed as bug#39828. The tests
  will need to be updated once MySQL fix that bug.
  
  One good side effect of this fix is that dict_table_t size has been
  reduced by 8 bytes because we have moved the autoinc_increment field to
  the row_prebuilt_t structure. See review-board for a detailed discussion.
