Set comment properly before calling mtr_report_test failed and report_failure_restart 

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.

mysqltest.test on Solaris and Mac. write_file produced nice files with all zeroes.

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

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>"

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

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

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

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

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.
