The main goal was to get the beginnings of module iteration and retrieval of CrashpadInfo in snapshot. The main change for that is to move crashpad_info_client_options[_test] down out of mac/. This also requires adding some of the supporting code of snapshot in ProcessReaderWin, ProcessSnapshotWin, and ModuleSnapshotWin. These are partially copied from Mac or stubbed out with lots of TODO annotations. This is a bit unfortunate, but seemed like the most productive way to make progress incrementally. That is, it's mostly placeholder at the moment, but hopefully has the right shape for things to come. R=mark@chromium.org BUG=crashpad:1 Review URL: https://codereview.chromium.org/1052813002
