[PATCH v2 10/18] Change how cooked index waits for threads

[Tom Tromey <tom@tromey.com>]

This changes the cooked index code to wait for threads in its
public-facing API.  That is, the waits are done in cooked_index now,
and never in the cooked_index_shard.  Centralizing this decision makes
it easier to wait for other events here as well.
