BUG/MINOR: mworker: Fix memory leak of mworker_proc members
The struct mworker_proc is not uniformly freed everywhere, sometimes leading
to leaks of the `id` string (and possibly the other strings).
Introduce a mworker_free_child function instead of duplicating the freeing
logic everywhere to prevent this kind of issues.
This leak was reported in issue #96.
It looks like the leaks have been introduced in commit 9a1ee7ac31c56fd7d881adf2ef4659f336e50c9f,
which is specific to 2.0-dev. Backporting `mworker_free_child` might be
helpful to ease backporting other fixes, though.
