lib-program-client: Fix building with compilers that have no typeof()

lib-program-client: Make sure we delay output in test This is to ensure that the client does not prematurely disconnect before output is sent.

lib-program-client: Use milliseconds in idle timeout

lib-program-client: Use restrict-access This makes the program-client execution behave more consistent to the rest of the core code.

lib-program-client: Do not use /tmp in testing

lib-program-client: Compiler warning fixes

lib-program-client: Add test suite for program client
