Chromium moved base::size() to base/cxx17_backports.h, so do the same in mini_chromium and update the users in Crashpad. Roll mini_chromium to 2f06f83f to make the new base header available. Bug: chromium:1210983 Change-Id: Ie3dc4c189dcdfcac030b95fe285f94abb29a27bf Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/2917779 Commit-Queue: Lei Zhang <thestig@chromium.org> Commit-Queue: Mark Mentovai <mark@chromium.org> Reviewed-by: Mark Mentovai <mark@chromium.org>
