to make them cancelable. Also,
* rename BulkDelete->BulkDeleteAll
this leaves room for a new method `BulkDelete(items storage.Items)` that
does a bulk deletion of a specified list of items, as opposed to
deleting _everything_. such a method would be used in the
`cleanupItems()` function found in utils.go, because when individual
deletes are fairly slow, that step takes way too long during tests.
* use BulkDelete method if available
nothing currently provides `BulkDelete(items storage.Items) error`,
but we made use of it with the Bigtable testing and code, and may make
use of it again when adding new kv backends.
* and eliminate the global context in test_iterate.go

We don't use reverse listing in any of our code, outside of tests, and
it is only exposed through libuplink in the
lib/uplink.(*Project).ListBuckets() API. We also don't know of any users
who might have a need for reverse listing through ListBuckets().
Since one of our prospective pointerdb backends can not support
backwards iteration, and because of the above considerations, we are
going to remove the reverse listing feature.

..although it ought to work for other storage.KeyValueStore needs as
well. it's just optimized to work pretty well for a largish hierarchy of
paths.
This includes the addition of "long benchmarks" for KeyValueStore
testing. These will only be run when -test-bench-long is added to the
test flags. In these benchmarks, a large corpus of paths matching a
natural ("real-life") hierarchy is read from paths.data.gz (which you
can get from https://github.com/storj/path-test-corpus) and imported
into a particular KeyValueStore. Recursive and non-recursive queries are
run on it to detect performance problems that arise only at scale.
This also includes alternate implementation of the postgreskv client,
which works in a less-bizarre way for non-recursive queries, but suffers
from poor performance in tests such as the long benchmarks. Once this
alternate impl is committed to the tree, we can remove it again; I just
want it to be available for future reference.
