- 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.

ported ActiveIO to use the backport.util.concurrent library so that it is API compatible with Java 5 as well as working from a newer, more heavily tested concurrent library

If journal was created too many times (in multiple test cases) it could run out of ByteBuffers.

- 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.

- General optmizations of hot spots. Lot's of code inlining, and making
stuff final. Less object allocations.

- Control file was not being closed on journal close.
- Started using the Disposable interface

- 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.

Make sure we the async task is working with right batched write.

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

Moved the journal api from activemq to activeio. Moved to using moving Packets instead of ByteBuffers and byte arrays.
