res/ari/config.c: Optimize conf_alloc() object init.

* Now conf_alloc() has more off nominal error checking.

* Eliminated RAII_VAR() use in conf_alloc().

* Eliminated a dubius shortcut when destroying cfg->general in
conf_destructor() that would cause a crash if cfg->general failed to get
allocated.

* Add some ACO registration section comments.
