Fix bug #12308 : do not roll back the whhole transaction in a lock wait timeout error, just roll back the latest SQL statement; note that the locks set in the latest SQL statements remain, as InnoDB does not know what locks were set in which SQL statement

  Better comments about auto-inc and SHOW TABLE STATUS

  Fix bug #12973 : set the table handle field auto_increment_value if ::info() is called with the flag HA_STATUS_AUTO

  Add a sanity check to page_rec_is_comp; a new univ.i macro UNIV_RELEASE_NOT_YET_STABLE controls such sanity checks that we will remove after the release is stable enough

  Fix a wrong debug assert in the previous patch

  Add more comments to row_search_for_mysql() and remove the ugly double use of the variable rec in that function

The idea of the patch is to separate statement processing logic,
such as parsing, validation of the parsed tree, execution and cleanup, 
from global query processing logic, such as logging, resetting
priorities of a thread, resetting stored procedure cache, resetting
thread count of errors and warnings.
This makes PREPARE and EXECUTE behave similarly to the rest of SQL
statements and allows their use in stored procedures.
This patch contains a change in behaviour:
until recently for each SQL prepared statement command, 2 queries
were written to the general log, e.g.
[Query]   prepare stmt from @stmt_text;
[Prepare] select * from t1 <-- contents of @stmt_text
The chagne was necessary to prevent [Prepare] commands from being written
to the general log when executing a stored procedure with Dynamic SQL.
We should consider whether the old behavior is preferrable and probably
restore it.
This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs
in Dynamic SQL reported before it was disabled).

  Fix bug #12947 : a consistent read could return inconsistent results; this bug was introduced in 5.0.5

- current_arena to stmt_arena: the thread may have more than one
'current' arenas: one for runtime data, and one for the parsed 
tree of a statement. Only one of them is active at any moment.
- set_item_arena -> set_query_arena, because Item_arena was renamed to 
Query_arena a while ago
- set_n_backup_item_arena -> set_n_backup_active_arena;
the active arena is the arena thd->mem_root and thd->free_list
are currently pointing at.
- restore_backup_item_arena -> restore_active_arena (with the same
rationale)
- change_arena_if_needed -> activate_stmt_arena_if_needed; this
method sets thd->stmt_arena active if it's not done yet.

  Always abort if node failure occured between startTransaction and commit
  (can later be improved by wl#2610)

  make sure not to cut log to early
