- Use only 1 thread to do the actual IO to the journal, the recent concurrent backport port had changed this
- Do safer locking of the control file. We now check to see if the same java process has locked the file.

Copied (2 times):

- Packets are now disposable so that they can be pooled.
- Generalize the journal PacketPool
- Changed the packet interface so that it's easier to know when an operation produces a new reference to the buffer. Methods that return
a Packet are not allways creating new references. Clients that are pooling should eventually dispose that reference.
- Small enhancment to the journal so that does not force if the batched write did not require a force.

- Tagged the journal classes final to help optimizers inline more.
- Reduced the number of seek calls done by caching the current seek location
- Logs are preallocated when the journal first starts up
- Added test to check to see if disconnected peers are detected.

Journal fixes:
- control file locking was not throwing an exception if the control file was allready locked.
- LogFileManager was not storing his state properly

Did a big re-org of the active journal implementation:
- Renamed classes so that they are more descriptive of what they do
- Got rid of needing sequence numbers: simplified the code through out
- We now store journal state in a control file for faster recovery times.
- Diabled checksuming by default to lower over head, and made the synchronization hot spots faster
