datadir can be saved in case of constantly failing servers
Remove datadirs each time all servers have been stopped thus limiting
the size of vardir.
The datadirs of failed tests have been saved and that should be
enough to diagnose any failures

we don't use Unix domin sockets for connection to server 

early versions of 5.1 and 5.0
Fix usage instruction of defaults_extra_file

moving the supressions from perl to SQL

Just treat var/tmp and $opt_tmndir that might be different or same. 

running on windows. Apparently Cygwin tries to emulate UNIX Socket and thus
fails to create one.

"eval use" it. Instead trap the error that occurs when creating the socket
on platforms that does not support it. 

Straigthen code to be more explicit

Also make it possible to specify a path to the suite, for example:
./mtr --suite=/some/path/to/suitedir 


mysql-test/lib/My/Find.pm:
  Extend 'my_find_paths' to glob path names

since it's used by the check

Don't allow unix socket path to be truncated 


mysql-test/lib/My/Platform.pm:
  Add check for unix socket path truncation
mysql-test/mysql-test-run.pl:
  Don't allow socket path to be truncated. Fail and ask user to correct the problem by
  using a shorter path with  --tmpdir

Fix warnings


mysql-test/mysql-test-run.pl:
  Symlink var/tmp to $opt_tmpdir if not using var/tmp

mysql-test/include/wait_until_connected_again.inc:
