b87873b221 Merge branch 'merge-innodb-5.6' into bb-10.0-vicentiu
This merge reverts commit 6ca4f693c1ce472e2b1bf7392607c2d1124b4293
from current 5.6.36 innodb.

Bug #23481444	OPTIMISER CALL ROW_SEARCH_MVCC() AND READ THE
                       INDEX APPLIED BY UNCOMMITTED ROW
Problem:
========
row_search_for_mysql() does whole table traversal for range query
even though the end range is passed. Whole table traversal happens
when the record is not with in transaction read view.

Solution:
=========

Convert the innodb last record of page to mysql format and compare
with end range if the traversal of row_search_mvcc() exceeds 100,
no ICP involved. If it is out of range then InnoDB can avoid the
whole table traversal. Need to refactor the code little bit to
make it compile.

032678ad18 MDEV-12091 Shutdown fails to wait for rollback of recovered transactions to finish
In the 10.1 InnoDB Plugin, a call os_event_free(buf_flush_event) was
misplaced. The event could be signalled by rollback of resurrected
transactions while shutdown was in progress. This bug was caught
by cmake -DWITH_ASAN testing. This call was only present in the
10.1 InnoDB Plugin, not in other versions, or in XtraDB.

That said, the bug affects all InnoDB versions. Shutdown assumes the
cessation of any page-dirtying activity, including the activity of
the background rollback thread. InnoDB only waited for the background
rollback to finish as part of a slow shutdown (innodb_fast_shutdown=0).
The default is a clean shutdown (innodb_fast_shutdown=1). In a scenario
where InnoDB is killed, restarted, and shut down soon enough, the data
files could become corrupted.

logs_empty_and_mark_files_at_shutdown(): Wait for the
rollback to finish, except if innodb_fast_shutdown=2
(crash-like shutdown) was requested.

trx_rollback_or_clean_recovered(): Before choosing the next
recovered transaction to roll back, terminate early if non-slow
shutdown was initiated. Roll back everything on slow shutdown
(innodb_fast_shutdown=0).

srv_innodb_monitor_mutex: Declare as static, because the mutex
is only used within one module.

After each call to os_event_free(), ensure that the freed event
is not reachable via global variables, by setting the relevant
variables to NULL.

    MDEV-10083: Orphan ibd file when playing with foreign keys

    Analysis: row_drop_table_for_mysql did not allow dropping
    referenced table even in case when actual creating of the
    referenced table was not successfull if foreign_key_checks=1.

    Fix: Allow dropping referenced table even if foreign_key_checks=1
    if actual table create returned error.

e9c10f9916 MDEV-7908: assertion in innobase_release_savepoint
Problem was that in XA prepared state we should still be able to
release a savepoint, but assertions were too strict.
