Sean Bright 7973b7474a res_agi.c: Ensure SIGCHLD handler functions are properly balanced. ...

Calls to `ast_replace_sigchld()` and `ast_unreplace_sigchld()` must be
balanced to ensure that we can capture the exit status of child
processes when we need to. This extends to functions that call
`ast_replace_sigchld()` and `ast_unreplace_sigchld()` such as
`ast_safe_fork()` and `ast_safe_fork_cleanup()`.

The primary change here is ensuring that we do not call
`ast_safe_fork_cleanup()` in `res_agi.c` if we have not previously
called `ast_safe_fork()`.

Additionally we reinforce some of the documentation and add an
assertion to, ideally, catch this sooner were this to happen again.

Fixes #922
