The bug is a regression introduced in 5.1 by the patch for bug28404.

Under some circumstances test_if_skip_sort_order() could leave some
data structures in an inconsistent state so that some parts of code
could assume the selected execution strategy for GROUP BY/DISTINCT as
a loose index scan (e.g. JOIN_TAB::is_using_loose_index_scan()), while
the actual strategy chosen was an ordered index scan, which led to
wrong data being returned.

Fixed test_if_skip_sort_order() so that when changing the type for a
join table, select->quick is reset not only for EXPLAIN, but for the 
actual join execution as well, to not confuse code that depends on its
value to determine the chosen GROUP BY/DISTINCT strategy.

When trying to get the requested amount of memory for the keybuffer,
the out of memory could be signaled if one of the tentative allocations
fail. Later the server would crash (debug assert) when trying to send
a ok packet with a error set.

The solution is only to signal the error if all tentative allocations
for the keybuffer fail.

The server used to trust blindly information from the client about
its capabilities. During the connection handshake the server sends
information about what it supports and then the client sends back a
set of capabilities which cover all of the server's or less.
Before this changeset the server didn't check whether the flags sent
by the client were valid for the server. For example, if the server
doesn't support compressed protocol but the client does and sends that
bit turned on, the server didn't check it. The change make the server code
less error prone to problems related to the value of THD::client_capabilities.

Clearly there is no vulnerability being fixed but this is a maintainenance
fix to prevent misusage in the future.

Problem: rpl_variables_stm.test used a character set and a collation which
are not included on all platforms.
Fix: replace the character set and collation by ones that are included on
all platforms. (rpl_variables_stm does not rely on which character set is
used, the only important aspect is the fact that it changes.)

Problem: if the IO slave thread is attempting to connect,
STOP SLAVE waits for the attempt to finish. 
It may take a long time.
Fix: don't wait, stop the slave immediately.

The reason is that we are using a sleep to wait for slave to reach the
slave_transaction_retries limit.
Fix: wait for the slave to stop instead. This is what we want to do, since
the slave stops when the limit is reached.

safe.
Fix: Move sql_mode: from the section of the test where safe variables are
tested, to the section where unsafe variables are tested.

WHERE f1 < n ignored row if f1 was indexed integer column and
f1 = TYPE_MAX ^ n = TYPE_MAX+1. The latter value when treated
as TYPE overflowed (obviously). This was not handled, it is now.
