Hi,

this is the second version of my patch series that tries to improve
performance of the connectivity check by only considering preexisting
refs as uninteresting that could actually have been advertised to the
client.

In v2 of this series, we introduced a new option `--visible-refs=` that
mostly acted as if `--all` was given, but its output was restricted to
only visible refs. As Peff rightly points out though, this is less
flexible than it needs to be. This new version instead introduces a new
option `--exclude-hidden=` that can be combined with `--all`, `--glob`,
`--branches` and so on to provide a more flexible interface.

The patch series is structured as following:

    - Patch 1-3 refactor multiple different parts of refs.c and
      revision.c so that they are more readily reusable.

    - Patch 4-5 implement `--exclude-hidden=` for git-rev-list(1) and
      git-rev-parse(1).

    - Patch 6 starts using that option in the connectivity check.
