Previously it was sufficient to use the old parser result for a Query if the DQL didn't change (Query::STATE_CLEAN), but now there must also be no changes to the filter collection of the EntityManager. In the old situation each Query object would create a hash of all the filter objects on it's own. That was not very efficient. This commit adds the state of the current filter collection to the EntityManager. The state will be set to FILTERS_STATE_DIRTY as a filter is enabled, removed or a parameter is set on a filter. The hash is also computed by the EntityManager, but only if the filter collection is dirty. This will prevent recalculation of the hash with each query.

Testing Lock-Support
The Lock support in Doctrine 2 is tested using Gearman, which allows to run concurrent tasks in parallel. Install Gearman with PHP as follows:
- Go to http://www.gearman.org and download the latest Gearman Server
- Compile it and then call ldconfig
- Start it up "gearmand -vvvv"
- Install pecl/gearman by calling "gearman-beta"
You can then go into tests/ and start up two workers:
php Doctrine/Tests/ORM/Functional/Locking/LockAgentWorker.php
Then run the locking test-suite:
phpunit --configuration <myconfig.xml> Doctrine/Tests/ORM/Functional/Locking/GearmanLockTest.php
This can run considerable time, because it is using sleep() to test for the timing ranges of locks.
