Improve sort algorithm for reorder, all test with smae name except for ending digit should be run after each other. 
Example of that is ndb_autodiscover[1-3]

Two implementations of "get_err_code_from_name", one use if mysqld_ername.h is available and oe if it's not
Declare "to_ptr" first in block 

Fix problem with specifying vardir, mysql_version_id was not yet available when vardir arguments is checked
Move the code to look for exe_mysqld earlier => to initial_setup
Fix warnings detected by running with "diagnostics"
Remove unused option "opt_result_ext"
Init "path_ndb_examples_dir"

into  neptunus.(none):/home/msvensson/mysql/mysql-4.1-maint

the "mysqld --version" command will print "/path/.libs/lt-mysqld  Ver x.x.x"

into  neptunus.(none):/home/msvensson/mysql/mysql-4.1-maint

Improve 'run_testcase_need_slave_restart' to detect if a slave restart really is necessary. 
So far all rpl test requires a slave restart, but for all other tests it can be skipped
Improve the sort order used by --reorder

Move call f dunction into "initialize_servers" so it's called also
in stress and bench mode

Cleanup .progress, .reject, .log and .warnings files produced by mysqltest

creating an environment variable is handled directly from the perl code.  

but having it on tmpfs gives a big speedup. 

- When --record is passed to mysqltest the whole testcase should be executed
as it normally is while the output form the test is acumulating
in ds_res. When test has finished ds_res should simply be written to the
specified result file(if any) instead of comapring it against the result file.
Simplify handling of --require and also the cecking of result files by splitting
check_result function into one  function 'check_require' that is specialised in
checking require's and leave 'check_result' to do just that.
- "mysqltest --record" has been considered unsafe, but with this really simple
logic, it should be safe to use.

from var/ to a tmpfs area and thereby speed up the execution of the testsuite
 significantly

Some variable names in 5.1 is soo long that there is no space inbetween 
name and value. Outputing a warning about it, as that should probably be fixed.
At least one space should be put between the name and value.

Improve check of wheter test case need slave cluster

Set the environment variable NDB_STATUS_OK to indicate that cluster is installed ok. This is actually not needed for this script as it will
skip ndb tests if cluster install failed. But provided for compatibility

I.e take advantage of the fact that a # comment is always terminated by a new line 
Add tests for the above

Fix detection of debug binaries. If mysqld ouputs "debug xx" in the variable list it's a debug binary

 - add missing DBUG_RETURN
 - Change type of st_error->code to uint, that should be more than enough
   to hold the error numbers between 1000 and around 2000

Use replace_regex to mask the output of file_id= in "show binlog events" that depends on previous tests
What is this? replace_regex in 4.1! :)

Set slave_load_path to ../../var/tmp in version prior to 5.0 to be compatible with mysql-test-run.sh

Create the mysqld.spec file with a unique name in mysql-test dir, $opt_var_dir haven't been created yet

Add paths for ndb binaries
Some more backport issues
