sendmsg() and recvmsg() are complicated to use. Refactor their usage into functions with a simpler, tested interface and use those instead. This also adds CreateCredentialSocketpair() to create a pair of connected sockets with SO_PASSCRED set. This option should be set before the possibility of any calls to sendmsg() with the socket pair to avoid race conditions in properly setting credentials. Also update the handler to use Strategy::kNoPtrace (which causes the crash dump to fail without breaking the socket connection) if the credentials were invalid, which can happen if SO_PASSCRED was set after the call to sendmsg() or if the sending process does not exist in this namespace.
