Bug #40116: Uncommited changes are replicated and stay on slave

Browse Source 
after rollback on master

When starting a transaction with a statement containing changes
to both transactional tables and non-transactional tables, the
statement is considered as non-transactional and is therefore
written directly to the binary log. This behaviour was present
in 5.0, and has propagated to 5.1.

If a trigger containing a change of a non-transactional table is
added to a transactional table, any changes to the transactional
table is "tainted" as non-transactional.

This patch solves the problem by removing the existing "hack" that
allows non-transactional statements appearing first in a transaction
to be written directly to the binary log. Instead, anything inside
a transaction is treaded as part of the transaction and not written
to the binary log until the transaction is committed.

In other words, we commit the transaction if and only if both of
the following are true:
- We are not in a transaction and committing a statement
- We are in a transaction and one (or more) of the following are
true:

OR
- A non-transactional statement is committed and there is
no statement cached
- We are in a transaction and a full transaction is committed
Otherwise, we accumulate the statement
