Fix warning about value from "*ptr++" not being used. Changed it to ptr++ 

mysql-test/lib/mtr_process.pl:
  Remove junk code/comments
  Moved the creation of var/log out of function mtr_kill_leftovers
mysql-test/mysql-test-run.pl:
  Rename 'kill_running_server' to more appropriate name 'kill_running_servers'
  If no var/log dir exists when mtr_kill_leftovers is started it should be created
  Remove "unless" syntax, too perlish
  Fix typo

MOve DBUG_ASSERT(result_file_name) to after DBUG_ENTER
Change type of "reconnect" variable from int to my_bool, reconnect didn't work on Solaris without that

Add DBUG_PRINT to show the value of mysql->reconnect

client/mysqltest.c:
  Fix typo

'run_testcase_need_master/slave_restart'
Remove the faulty qw
Only look for mysql_fix_privilege_tables if not windows


mysql-test/lib/mtr_cases.pl:
  Move all code to determine when to restart into 'run_testcase_need_master/slave_restart' 
  Add possibility to wite --force-restart in -master.opt file, this will force a restart and
  since master is not started with any special options there is no need to restart
  again afterwards.
mysql-test/mysql-test-run.pl:
  Remove the qw surrounding ENV{'LD_LIBRARY_PATH'}
  Only look for the sh script mysql_fix_privileges when not on windows
  Remove warnings about using unitialized variables
  Improve the restart logic, eall code to determine when to restart is
  now in run_testcase_need_master_restart and run_testcase_need_slave_restart
mysql-test/t/bdb-alter-table-2-master.opt:
  Use --force-restart
mysql-test/t/not_embedded_server-master.opt:
  Use --force-restart

client/mysqltest.c:
  Remove vsnprintf() and DBUG_PRINT from die() function, as it's not portable to Windows, and it's not allowed to
  call vsnprintf() and then vfprintf() with the same args.
  Can't just print the buffer here, because the buffer is a fixed size.
  If the message is longer than will fit int he buffer, it would get
  truncated on Unix, and the full thing would be printed on Windows.
  This DBUG_PRINT isn't important enough for this hassle, so just get rid
  of it.

to run the whole testcase to find wich testcases need to be checked more carefully
and the just "copy and paste" the suspicious test case names to 
a new mysql-test-run.pl command. 


mysql-test/mysql-test-run.pl:
  Mark test cases that fails "check_testcase"
  Make run_check_testcase return  value indicating if check failed
mysql-test/include/check-testcase.test:
  New BitKeeper file ``mysql-test/include/check-testcase.test''

vsnprintf is not available on win2003-x86 host, as this is just a debug functionality - disable it for now.

When looking for client binary directories it necessary to look for the one s that are "deep down" first.

Make the mysqld_variables hash global so it can be used throughout the program 

strcmp -> strncmp

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 

mysql-test/lib/mtr_report.pl:
  Use tinfo's comment as primary place to look for error message

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"


mysql-test/lib/mtr_cases.pl:
  Set default number of slave to 0
  Remove unused/uninitialized "$opt_result_ext"
mysql-test/lib/mtr_report.pl:
  Remove unused/uninitialized "$opt_result_ext"

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

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


mysql-test/mysql-test-run.pl:
  Modify regex for parsing mysqld version as the mysqld is sometimes a libtool wrapper and
  the "mysqld --version" command will print "/path/.libs/lt-mysqld"

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


mysql-test/r/subselect.result:
  Auto merged
mysql-test/t/ps.test:
  Auto merged
mysql-test/t/subselect.test:
  Auto merged

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


mysql-test/lib/mtr_cases.pl:
  Improve the sort order used by reorder
mysql-test/mysql-test-run.pl:
  Improve 'run_testcase_need_master_restart' to require restart if master is not already started
  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

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


client/mysqltest.c:
  Add printout of file in which warning was detected
mysql-test/include/ctype_like_escape.inc:
  Remove warnings, convert -- comments to # comments
mysql-test/mysql-test-run.pl:
  Cleanup all files produced by mysqltest before starting mysqltest again

mysql-test/mysql-test-run.pl:
  Add policy directive about keeping mysqltest framework tools identical in all versions
  Cleanup the initial comment to reflect current state

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

but having it on tmpfs gives a big speedup. 


mysql-test/mysql-test-run.pl:
  Make use of opt_mem and let 4.1 allow vardir to be set. Still relies on the var/ directory
  but having it on tmpfs gives a big speedup.

mysql-test/mysql-test-run.pl:
  Use same location for slave-load-tmpdir in all versions
mysql-test/mysql-test-run.sh:
  Use same location for slave-load-tmpdir in all versions
mysql-test/r/rpl_loaddata.result:
  Update result after changing slave-load-tmpdir to use a shorter path
mysql-test/r/rpl_loaddatalocal.result:
  Update result after changing slave-load-tmpdir to use a shorter path
mysql-test/r/rpl_log.result:
  Update result after changing slave-load-tmpdir to use a shorter path
mysql-test/t/rpl_loaddatalocal.test:
  Use MYSQLTEST_VARDIR when specifying path to load from(backport from 5.0)
  Use new command "remove_file" instead of s"ystem rm"

- 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.
