[PATCH v2 1/3] bundle-uri: copy all bundle references ino the refs/bundle space

["Scott Chacon via GitGitGadget" <gitgitgadget@gmail.com>]

From: Scott Chacon <schacon@gmail.com>

When downloading bundles via the bundle-uri functionality, we only copy the
references from refs/heads into the refs/bundle space. I'm not sure why this
refspec is hardcoded to be so limited, but it makes the ref negotiation on
the subsequent fetch suboptimal, since it won't use objects that are
referenced outside of the current heads of the bundled repository.

This change to copy everything in refs/ in the bundle to refs/bundles/
significantly helps the subsequent fetch, since nearly all the references
are now included in the negotiation.
