[PATCH v5 00/15] add git-bugreport tool

From: Emily Shaffer <emilyshaffer@google.com>

This topic branch depends on the patch mailed in lore.kernel.org/git/20191211233820.185153-1-emilyshaffer@google.com in order to display scopes for configs gathered during "bugreport: add config values from safelist".

I'll summarize v4-v5. Since v4 has languished for some time, I don't think an interdiff is too helpful, so I won't include one. Bonus, the code is much simplified from some suggestions from Junio on how to inspect objects, so I hope it's easy to review anyways.

Throughout, did some style changes away from C++ bad habits. Otherwise, as listed:

Emily Shaffer (15):
  bugreport: add tool to generate debugging info
    (no change)
  help: move list_config_help to builtin/help
    Changed to agree with f3719846134

  bugreport: gather git version and build info
    Style only

  help: add shell-path to --build-options
    (no change)

  bugreport: add uname info
    Removed nodename for privacy reasons

  bugreport: add compiler info
    Moved glibc tattling into compat/.

    I appreciate a close look at this one - I think I understood the
    right way to go about a compat/ util but it's the first one I've
    done.

  bugreport: add curl version
    Moved curl tattling from git-http-fetch into git-remote-curl

  bugreport: include user interactive shell
    Stop depending on a compiler quirk to save us from segfault

  bugreport: generate config safelist based on docs
    Changed to agree with f3719846134
    Cleaned up script a little

  bugreport: add config values from safelist
    Made git-bugreport dependent on generated safelist header

  bugreport: collect list of populated hooks
    No change.
    Per https://lore.kernel.org/git/20191216235131.GL135450@google.com,
    should we even keep this patch?

  bugreport: count loose objects
    Use helpers from object-store.h instead of manually walking the
    filesystem.

  bugreport: add packed object summary
    Use helpers from object-store.h instead of manually walking the
    filesystem.

  bugreport: list contents of $OBJDIR/info
    (no change)

  bugreport: summarize contents of alternates file
    Rephrase commit message to explain why I can't use the helpers in
    object-store.h.

Thanks.
 - Emily
