- If USER is given, all threads for that user is signaled
- If SOFT is used then the KILL will not be sent to the handler. This can be used to not interrupt critical things in the handler like 'REPAIR'.
Internally added more kill signals. This gives us more information of why a query/connection was killed.
- KILL_SERVER is used when server is going down. In this case the users gets ER_SHUTDOWN as the reason connection was killed.
- Changed signals to number in correct order, which makes it easier to test how the signal should affect the code.
- New error message ER_CONNECTION_KILLED if connection was killed by 'KILL CONNECTION'. Before we got error ER_SHUTDOWN.

If a thread is killed in the server, we throw "shutdown" only if one is actually in
progress; otherwise, we throw "query interrupted".
Control-C in the mysql command-line client is "incremental" now.
First Control-C sends KILL QUERY (when connected to 5.0+ server, otherwise, see next)
Next Control-C sends KILL CONNECTION
Next Control-C aborts client.
As the first two steps only pertain to an existing query,
Control-C will abort the client right away if no query is running.
client will give more detailed/consistent feedback on Control-C now.
client/mysql.cc:
Extends Control-C handling; enhances up feedback to user.
On 5.0+ servers, we try to be nice and send KILL QUERY first
if Control-C is pressed in the command-line client, but if
that doesn't work, we now give the user the opportunity to
send KILL CONNECTION with another Control-C (and to kill the
client with another Control-C if that somehow doesn't work
either).

+ Removal of a lot of other weaknesses found
+ modifications according to review
The problem is that since MyISAM's concurrent_insert is on by
default some concurrent SELECT statements might not see changes
made by INSERT statements in other connections, even if the
INSERT statement has returned.
The solution is to disable concurrent_insert so that INSERT
statements returns after the data is actually visible to other
statements.

rows need to be visible before a SELECT statement is queued in
another connection.
Remove sleep at the start of the test, it's not necessary to log
the result of the processlist command, showing the warnings has
the same end result.
