aee4f7acc2 Remove queueing from Lock
It was buggy (didn't work) and was never actually used.

Why never actually used: for it to be used executeWithLock has to be called
with different requesters on the same lockId. That never happend in the code.

How it was buggy: Logically, the queue is deleted on release of the lock (meaning it was
meaningless the only time it mattered - when the lock isn't taken). In
addition, a different bug meant that having items in the queue prevented the
lock from being released forcing all other tasks to have to wait for lock
timeout even if the task that acquired the lock is long done.

Alternative: fix the queue. This would mean we don't want to delete the lock on release (since we want to keep the queue). Instead, we resave the same lock with expiration date being START_OF_TIME. In addition - we need to fix the .equals used to determine if the lock the same as the acquired lock - instead use some isSame function that ignores the queue.

Note: the queue is dangerous! An item (calling class / action) in the first place of a queue means no other calling class can get that lock. Everything is waiting for the first calling class to be re-run - but that might take a long time (depending on that action's rerun policy) and even might never happen (if for some reason that action decided it was no longer needed without acquiring the lock) - causing all other actions to stall forever!

c458c05801 Rename Java packages to use the .google TLD
The dark lord Gosling designed the Java package naming system so that
ownership flows from the DNS system. Since we own the domain name
registry.google, it seems only appropriate that we should use
google.registry as our package name.

5012893c1d mv com/google/domain/registry google/registry
This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.
