For processes that start very early, atrace initialization can cause
an selinux denial, so make sure it's possible to disable it and avoid
the call to open "trace_marker".
Bug: 63927601
Test: disable atrace early in vold, ensure that selinux denial is
avoided.

Just the minimial changes to get this to actually build, because otherwise
we always bog down trying to rewrite everything (when the real answer
is usually "stop using libcutils, it's awful").
This doesn't move a handful of files: two are basically just BSD libc
source, a couple have outstanding code reviews, and one can be deleted
(but I'll do that in a separate change).
I'm also skipping the presubmit hooks because otherwise clang-format
wants to reformat everything. I'll follow up with that...
Bug: N/A
Test: builds
