This CL, based on https://chromium-review.googlesource.com/c/crashpad/crashpad/+/689745 adds a cross-platform database implementation side-by-side with the existing macOS and Windows implementations. The generic implementation is used for Linux, Android and Fuchsia. The database uses the directory structure from the macOS implementation, but stores report metadata in companion files for each report, rather than using filesystem attributes. The database uses lockfiles (companion files opened with O_EXCL) to protect report access because they are widely supported across filesystems. Lost lockfiles are removed after 3 days, along with any reports or metadata they were protecting. Bug: crashpad:206 Change-Id: I086e9001350e4446dd2f8c12fd3817377f509d3e Reviewed-on: https://chromium-review.googlesource.com/919527 Commit-Queue: Joshua Peraza <jperaza@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org>
