[PATCH 23/24] clone: unbundle the advertised bundles

["Derrick Stolee via GitGitGadget" <gitgitgadget@gmail.com>]

From: Derrick Stolee <derrickstolee@github.com>

A previous change introduced the transport methods to acquire a bundle
list from the 'bundle-uri' protocol v2 verb, when advertised _and_ when
the client has chosen to enable the feature.

Teach Git to download and unbundle the data advertised by those bundles
during 'git clone'.

Also, since the --bundle-uri option exists, we do not want to mix the
advertised bundles with the user-specified bundles.
