Problem was that trx might have not been started when we enter release
savepoint, this can happen when trx with savepoint is already aborted
or when we try to release non-existing savepoint.
Analysis: When database is migrated from 5.5 or earlier and
database needs crash recovery, there is possibility that
SYS_DATAFILES system table does not exists, but
crash recovery in function dict_check_tablespaces_and_store_max_id()
assumes that SYS_DATAFILES exists.
Fix: If SYS_DATAFILES does not exists, create it before
we end up to function dict_check_tablespaces_and_store_max_id()
on crash recovery.

xtradb fixes for windows, again
have been created by the last addition of new CONNECT features.
The version previous to this one is a preliminary test version and
should not be distributed.
- Handle indexed UPDATE/DELETE. Previously this was just tested and
an error message send when it could not be done. Now CONNECT can
do it in all the cases. It is done by a MRR like tchnique by making
a list of all update or delete to do, sort them, then execute them.

- Differenciate Cardinality that returns a true or estimated table size
and GetMaxSize that return a value equal or greater than the table
row number. This fixes the errors of non matching opt files.

- Fix some errors and issues when making index and opt files.
Erase opt and index files for void tables.
Fix wrong calculation of Block and Last in MakeBlockValues.
Invalidate indexes before making opt file.
Fully handle blocked variable tables. Make opt file for blocked
variable tables even when they have no optimised colums.

really occur now that GetMaxSize is sure)
Don't use XXROW index for DBF tables because of soft deleted lines.

Analysis: If buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH then
buf_page_in_file(bpage) might not be true.
Fix: ut_a(buf_page_in_file(bpage) || buf_page_get_state(bpage) == BUF_BLOCK_REMOVE_HASH);
This bug only happens in case of paritioned tables used in LOCK TABLES and implicit_commit() was called
(as part of trying to execute a CREATE TABLE withing lock tables)
The problem was that Aria could not move the tables from one transaction to the new one, as thd->open_tables contained
a partitioned tables and not an Aria table.
Fix:
- Store a list of all open tables that are part of a share in share->open_tables
- In maria::implict_commit() use transaction->used_tables & share->open_tables to find out which tables
was part of the current transaction instead of using thd->open_tables, which may contain partitioned tables.

This problem affects only debug builds on PPC64.
There are at least two race conditions around
rw_lock_debug_mutex_enter and rw_lock_debug_mutex_exit:
- rw_lock_debug_waiters was loaded/stored without setting
appropriate locks/memory barriers.
- there is a gap between calls to os_event_reset() and
os_event_wait() and in such case we're supposed to pass
return value of the former to the latter.
Fixed by replacing self-cooked spinlocks with system mutexes.
These days system mutexes offer much better performance. OTOH
performance is not that critical for debug builds.
