The new methods on LruCache are needed by libhwui to manage
the cache of paths.

8185e47822 Add an LRU cache plus hashing primitives
This patch adds a hashtable-based LRU cache. This should be
significantly higher performance than the GenerationCache it is intended
to replace. It is a large part of the fix for bug 7271109
TextLayoutCache low-level performance issues.

We added a new method to BasicHashtable to detect when rehashing is
needed, because the internal linked list pointers would get invalidated
by that rehashing.

Also, the hash_type specialized to pointers had a small flaw.
