autotest cannot run mysqltestrun as it no longer functions with external clusters

How to repeat:
look at autotest output

Suggested fix:
make mysql-test-run.pl again allow connections to other clusters

This affects also every extra QA test running against an already started server.
I am now blocked because of this bug in several WL tasks.
Therefore I rise the priority to P1.

How to reproduce this bug:
./mysql-test-run.pl --start-and-exit
# I hope there is no bug within the next command line  :-)
./mysql-test-run.pl --extern --socket=var/tmp/master.sock alias
Logging: ./mysql-test-run.pl --extern --socket=var/tmp/master.sock alias
MySQL Version 5.1.13
mysql-test-run: WARNING: Could not parse variable list line :

Matthias, it's actually a different problem for --extern not working. For NDB we can have mysql-test-run.pl start its own mysql server, but that server should connect to an existing cluster.

the code for --extern for a mysql server is different.

there may already be a bug for this... there was talk a few days ago on #mysql or #dev on internal irc

The following patch seems to help me:

I assume it's the problem that can be seen on http://ndb.mysql.com/~ndbdev/report.pl?id=1368 that this bug concerns

atrt-mysql-test-run --force 	FAILED(TEST) 	  	00:00:06 	log 	X

With the log of first ndb api like this:
Logging: ./mysql-test-run --with-ndbcluster --ndb-connectstring=dl145a:14000 --force

Looks good to me - have briefly tested and seems to work.

So this should enable us to start using it with atrt again.
