Don't allcoate a new math/rand every request.

Use a global math/rand instance, rather than re-allocating one for each
request.

Create unbuffered Tumble entry point for LogDog.

Add RegisterInTransaction, an entry point for Tumble that initiates a
standard datastore transaction, performs an operation, and registers the
ensuing mutation against it. This is different from RunMutation in that
it doesn't require a Mutation as a starting point and also doesn't
create a transaction buffer.

Leverage this in LogDog's "registerStream" to reduce the overhead of
stream registration.

Add treapstore, a treap-based in-memory data store

Add treapstore, which leverages gtreap implementation at
"github.com/luci/gtreap" to build a store.

This is intended as a lightweight and dedicated replacement for gkvlite
in "github.com/luci/gae/impl/memory".

Fix race in treapstore test.

The treapstore test currently asserts that at least one read happens.
The first round, however, it is possible that no writes happen before
the read round finishes. Adjust the test to accommodate this.

The check itself is not very useful. The purpose of this test is to
expose a bunch of potential races and assert that they aren't actually
races.
