This was done in Chromium’s local copy of Crashpad in 562827afb599. This change is similar to that one, except more care was taken to avoid including headers from a .cc or _test.cc when already included by the associated .h. Rather than using <stddef.h> for size_t, Crashpad has always used <sys/types.h>, so that’s used here as well. This updates mini_chromium to 8a2363f486e3a0dc562a68884832d06d28d38dcc, which removes base/basictypes.h. e128dcf10122 Remove base/move.h; use std::move() instead of Pass() 8a2363f486e3 Move basictypes.h to macros.h R=avi@chromium.org Review URL: https://codereview.chromium.org/1566713002 .
