Remove PHP_INT_MAX constant

[oqq]

I would prefer to using null instead of PHP_INT_MAX in load methods and let decide the implementation how to handle this value. In most cases this value could be ignored in query if it is null, if it is not necessary for index usage. Also, PHP_INT_MAX has a higher memory footprint than null. Even it is not always true that PHP and the underlying storage uses the same cpu architecture. (32bit vs. 64bit)

I have not investigate much in that issue. Maybe there is a good reason for PHP_INT_MAX instead of null. But if not, please let us remove that constant. I always feel bad if I have to use this constant with event_store.

What about loadReverse then?

The EventStore implementation has to know how to handle null. e.g the PdoEventStore removes the nofrom the where clause OR implement PHP_INT_MAX again. Its up the the event store implementation.

With PHP_INT_MAX I am not able to get if a user says "no limit" or "a big number to start".
