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 Change-Id: I59e611e95c85bdbefa779ef69b32b9dd4ee203e2
