Various fixes for upstream acceptance, and formatting
...
Removes the ctime tracking and access. Reverts NewFrom() changes from
upstream, and adds NewFromWithLRU() in place of it.

For inclusion with upstream projection, Cache.New() has been reverted to
...
its former argument list, and Cache.NewWithLRU() as been added to allow
setting maxItems. cache_test has also been reverted.

Performance was suffering with very large caches, when the cache was
...
under maxItems pressure. Reverted the LRU handler back to the first
iteration: lazy deletion via the janitor, with bulk removal.

Consistency.

Injected LRU capabilities that simply:
...
* ensures that when an item is added, if the number of unexpired items
>= maximum number of items specified, the oldest (based on ACCESS) is
expired
* when an item is "gotten", or "set", the access time is updated
The existing janitor system is unchanged, and used to actually delete
the items.
The only change from a consumer standpoint, is one addition parameter at
the end of a "New" call, that specifies the maximum number of items to
allow, or 0, if you want to disable the LRU at all.

Use an RWMutex instead of a Mutex, making Get a read operation only (this slightly changes the eviction behavior: lookup doesn't completely expunge an expired item, but the janitor still will at the next cleanup.) Also, use the same RWMutex in Load and Save (thanks, Alan Shreve)
