Joshua Peraza 8d0d999d92 Add a cross-platform database implementation
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.
