Added support for segment based recovery. For now, Stasis doesn't support hybrid recovery, so mixing page deallocation and segments will make recovery corrupt data / segfault.

Fix for Issue 1. Reworked log format so that nested top actions do not need to look up old entries during forward operation. This saves log bandwidth and avoids the bug that caused the performance regression

Major refactoring:
...
- Changed operations to take only two arguments
- No more hacks regarding log argument sizes
- Set pageid = INVALID_PAGE if you want a logical operation
- Ported operation implementations to new api; exposed + fixed a number of concurrency bugs
- More fixes to prepare
- Fixed to nested top actions
- More coherent operations api / recovery implmentation
- TnaiveHash* and Tinstant* are (and were already) broken, and are set for removal
- Removed some instances of fail_unless
- Fixed design flaws in blob implementation.
- New naming convention for operation callback functions.
