Make lib/isc/app.c opaque and thread-safe
This work cleans up the API which includes couple of things: 1. Make the isc_appctx_t type fully opaque 2. Protect all access to the isc_app_t members via stdatomics 3. sigwait() is part of POSIX.1, remove dead non-sigwait code 4. Remove unused code: isc_appctx_set{taskmgr,sockmgr,timermgr}
