* dll_init.cc: Use fabort in favor of api_fatal and fork_info->abort where

appropriate throughout.
(fabort): Define.
(dll_list::topsort): Don't print sorting information.  Fix formatting.
(dll_list::topsort_visit): Fix formatting.
(dll_list::load_after_fork_impl): Perform comment fixups.
* sigproc.cc (child_info_fork::abort): (for now?) Always print cause of fork
failure.
* include/sys/strace.h (strace_vprintf): Remove _STRACE_NOTALL when printing.
We really do want to see this.
