transactions that are started before the rollback of incomplete
transactions has finished may have an inconsistent view of the
secondary indexes.

btr_cur_upd_lock_and_undo(): Add the parameter mtr.

page_set_max_trx_id(): Allow mtr to be NULL.  When mtr==NULL, do not
attempt to write to the redo log.  This only occurs when creating a
page or reorganizing a compressed page.  In these cases, the
PAGE_MAX_TRX_ID will be set correctly during the application of redo
log records, even though there is no explicit log record about it.

btr_discard_only_page_on_level(): Preserve PAGE_MAX_TRX_ID.  This
function should be unreachable, though.

btr_cur_pessimistic_update(): Update PAGE_MAX_TRX_ID.

Add some assertions for checking that PAGE_MAX_TRX_ID is set on all
secondary index leaf pages.

  branches/5.1: Prevent a race condition in innobase_commit() by ensuring
  that innodb_commit_concurrency>0 remains constant at run time. (Bug #42101)

  srv_commit_concurrency: Make this a static variable in ha_innodb.cc.

  innobase_commit_concurrency_validate(): Check that innodb_commit_concurrency
  is not changed from or to 0 at run time.  This is needed, because
  innobase_commit() assumes that innodb_commit_concurrency>0 remains constant.
  Without this limitation, the checks for innodb_commit_concurrency>0
  in innobase_commit() should be removed and that function would have to
  acquire and release commit_cond_m at least twice per invocation.
  Normally, innodb_commit_concurrency=0, and introducing the mutex operations
  would mean significant overhead.

This addresses Mantis Issue #23 in InnoDB Hot Backup and some
of MySQL Bug #41609.

In MLOG_FILE_CREATE, we need to distinguish temporary tables, so that
InnoDB Hot Backup can work correctly.  It turns out that we can do this
easily, by using a bit of the previously unused parameter for page number.
(The page number parameter of MLOG_FILE_CREATE has been written as 0 
ever since MySQL 4.1, which introduced MLOG_FILE_CREATE.)

MLOG_FILE_FLAG_TEMP: A flag for indicating a temporary table in
the page number parameter of MLOG_FILE_ operations.

fil_op_write_log(): Add the parameter log_flags.

fil_op_log_parse_or_replay(): Add the parameter log_flags.
Do not replay MLOG_FILE_CREATE when MLOG_FILE_FLAG_TEMP is set in log_flags.
This only affects ibbackup --apply-log.  InnoDB itself never replays file
operations.

and undo_no_t. Each type is still defined as dulint.

This is an initial step towards replacing dulint with a 64-bit data type.
Because modern compilers have no trouble supporting 64-bit arithmetics
even on 32-bit targets, the dulint struct is a relic that should go.

The last remaining major use of dulint is dictionary IDs
(table, index, and row ids).
