igbinary 3.0.0a2

igbinary extension

Igbinary is a drop in replacement for the standard php serializer. Instead of
the time and space consuming textual representation used by PHP's serialize(), igbinary stores php data
structures in a compact binary form. Savings are significant when using
memcached or similar memory based storages for serialized data.

* Don't use empty string for serializing empty $_SESSION array, it breaks some save handlers. (Issue #231)
Continue treating the empty string as the empty $_SESSION array when unserializing.
