12671	Add set_many, delete_many, clear to cache	Jeff Balogh	Jeff Balogh	"The attached patch adds all three, with accompanying tests and docs.

`set_many` and `delete_many` are convenient, but not really any big gain for non-memcached backends.  For memcached, they're an improvement if you're setting or deleting a bunch of keys at once, since you avoid extra latency and network traffic.  It also provides symmetry with `get_many`.

`clear` is nice for tests and development when you need a full flush, and in production when there's a code upgrade that changes the shape of cached objects.

I can split the patch into multiple, smaller patches if it makes things easier.  I was in there and wanted all three, so I wrote everything at once.

On the docs: the cache section is getting littered with `versionadded` directives, and the new methods might be getting kind of lost.  A new ""High Efficiency"" section might be in order, to separate methods that act on a single key from methods that act on many keys (get_many, set_many, delete_many, and cache).  Thoughts?

Also, I'm not excited about continuing the (timeout=0 => default timeout) debacle, but it's better for consistency."		closed	Core (Cache system)	1.2-alpha		fixed			Unreviewed	1	0	0	0	0	0
