When calculating what features to use for _this_ test run, don't look at test that already are deterined to be skipped

Add verbose printouts making it possible to see what happens.
Make it an error if trying to stop a non existing timer
Print warning if fork fails.

We don't set null_value to 0 in the Item_func_compress::val_str() for 
not-NULL results.


mysql-test/r/func_compress.result:
  Fix for bug #23254: COMPRESS(NULL) makes all futher COMPRESS() calls on same Item return NULL
    - test result.
mysql-test/t/func_compress.test:
  Fix for bug #23254: COMPRESS(NULL) makes all futher COMPRESS() calls on same Item return NULL
    - test case.
sql/item_strfunc.cc:
  Fix for bug #23254: COMPRESS(NULL) makes all futher COMPRESS() calls on same Item return NULL
    - set null_value.

Now also detects "source nnnn;" command, previous version only detected
"--source"

Improve function that finds the reason why test was skipped, the old version only looked at the ast line, but there might be some additional debug info there so it's better to scan the whole file. 
There should be only one line that says "reason: <reason>"

mysql-test/r/csv.result:
  Update result after add of missing semicolon

This will hopefully avoiid annoying crashes when running with --debug
Fix warnings  from the above in mysqltest.c


client/mysqltest.c:
  Fix format specifier warnings in mysqltest.c
include/my_dbug.h:
  Add ATTRIBUTE_FORMAT specifier to _db_doprnt, which is used by DBUG_PRINT
  This will hopefully avoiid annoying crashes when running with --debug

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

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 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.

set. This has always worked because when flag is !=0 then
HA_VAR_LENGTH_KEY is always set. Therefore, a test case cannot
reveal a faulty behavior.

Fix for bug#23074: typo in myisam/sort.c


myisam/sort.c:
  fix typo. Nevertheless, it has worked as expected
  because when a bit in flag is set HA_VAR_LENGTH_KEY has
  been always set too. Actually, no problem exposed through
  DDL.

The bug is present only in 4.1, will be null-merged to 5.0

For InnoDB, check value of thd->transaction.all.innodb_active_trans instead of thd->transaction.stmt.innobase_tid to see if we really need to rollback.
