Remove race situations that occur when removing pidfiles. Primarily each process should remove its own
pidfile, secondly it should be removed by the process that created it and _only_ if it's
certain the process is dead. Third, mysql-test-run.pl will remove the pidfile when process has been killed.
- Set state of an instance to STARTING _before_ calling instance->start()
- Check that pidfile of instance has been created before changing STARTING => STARTED
- Only remove the pidfile if IM kills an instance with SIGKILL, otherwise the instance will remove it itself

to start instance manager.

The problem was that if IM failed to start, test suite aborts.

The fix is to mark current test as failed, and continue running
test suite.

The fix affects only test suite.

The patch affects only test suite and has the following changes:

1. On starting Instance Manager -- added code for waiting for guarded
mysqld instances to create PID files;
2. Polishing;
3. Move IM-related operations out of mtr_process.pl into new dedicated
for IM file -- mtr_im.pl

In 5.0 we made LOAD DATA INFILE autocommit in all engines, while
only NDB wanted that. Users and trainers complained that it affected
InnoDB and was a change compared to 4.1 where only NDB autocommitted.
To revert to the behaviour of 4.1, we move the autocommit logic out of mysql_load() into
ha_ndbcluster::external_lock().
The result is that LOAD DATA INFILE commits all uncommitted changes
of NDB if this is an NDB table, its own changes if this is an NDB
table, but does not affect other engines.
Note: even though there is no "commit the full transaction at end"
anymore, LOAD DATA INFILE stays disabled in routines (re-entrency
problems per a comment of Pem).
Note: ha_ndbcluster::has_transactions() does not give reliable results
because it says "yes" even if transactions are disabled in this engine...

Fix problem where mysql-test-run.pl fails to start up the mysqld after a failed test. Shows up on win hosts where one failed test case make subsequent ones fails with error "Could not open connection 'default': 2003 Can't connect to MySQL server on 'localhost'"

21913: DATE_FORMAT() Crashes mysql server if I use it through mysql-connector-j driver.

Variable character_set_results can legally be NULL (for "no conversion.")
This could result in a NULL deref that crashed the server.  Fixed.

(Although ran some additional precursory tests to see whether I could break
anything else, but no breakage so far.)
