[infinispan-dev] First working version of lock/unlock API

[Vladimir Blagojevic]

Hey Manik,

Do not need Mircea's help. I turned on debugger and went to investigate 
why I was getting NPEs in those invocations. So now I have first working 
version of locking/unlocking working with transactions (see 
SyncReplLockingTest). Will add more tests and continue to play with this 
one.

All in all - loads of fun. As soon as I am done with this one and 
implicit transactions I want more tasks :)

Regards,
Vladimir
