Some services are not native android services and therefore don't log
via the normal mechanisms. This gives developers an option to have
their stdout/stderr logs sent directly to kmsg.
Test: see test prints to kernel log

There is a race condition with Service::Start and socket creation.
Since socket creation currently happens after the fork(), it's
possible that init can continue executing other commands before the
socket is created. If init starts another service that relies on that
socket, it isn't guaranteed to be available.
Particularly, we've seen this with hwservicemanager starting after
logd, but hwservicemanager's logs sometimes not showing up.

clang-tidy hinted that some of this code wasn't right. Looking
deeper, there is really not much related to file and socket
descriptors, except that they're published in similar ways to the
environment. All of the abstraction into a 'Descriptor' class takes
us further away from specifying what we really mean.
This removes that abstraction, adds stricter checks and better errors
for parsing init scripts, reports sockets and files that are unable to
be acquired before exec, and updates the README.md for the passcred
option.
Test: build, logd (uses files and sockets) works

android-base:
* Add NOLINT for expanding namespace std for std::string* ostream
overload
libdm:
* Fix missing parentesis around macro parameters
init:
* Fix missing CLOEXEC usage and add NOLINT for the intended
usages.
* Fix missing parentesis around macro parameters
* Fix erase() / remove_if() idiom
* Correctly specific unsigned char when intended
* 'namespace flags' should be signed, since 'flags' it signed for
clone()
* Add clear to property restore vector<string> to empty after move
* Explicit comparison against 0 for strcmp
Test: build

Now that Result<T> is actually expected<T, ...>, and the expected
proposal states expected<void, ...> as the way to indicate an expected
object that returns either successfully with no object or an error,
let's move init's Result<Success> to the preferred Result<void>.

Factors out utility functions into service_utils.h/cpp, so that they
can be reused by the upcoming native zygote.
