This adds support for using debug tarballs located on the local machine instead of only ones on remote servers. (If the first argument is a local file, we use it; otherwise, we try to download it.) It also makes us download the (tiny) minidumps before the (huge) tarball so we can bail out quickly if the minidump URL is wrong. BUG=chromium-os:19565 TEST=manual: ran it successfully with both local and remote tarballs and checked that it fails early when given an invalid minidump path Change-Id: Ie427b50e4b7e37c6c81a1137eb34a28e25f32c8e Reviewed-on: http://gerrit.chromium.org/gerrit/8910 Tested-by: Daniel Erat <derat@chromium.org> Reviewed-by: Steven Bennetts <stevenjb@chromium.org> Reviewed-by: Thieu Le <thieule@chromium.org> Commit-Ready: Daniel Erat <derat@chromium.org>
