After experimenting with an adaptation of pidof to the new pids interface, it became apparent that vectorized versions of those command lines would be necessary. So this commit adds that option and the strv result type. And since the stage had been set, a vectorized version of PROCPS_PIDS_ENVIRON & PROCPS_PIDS_CGROUP was added. Lastly, any use of 'const' in the result structure was removed so callers need not be bothered with casts and compiler warnings. Hopefully, they'll respect a stack.
