- Add write_logd, read_logd and control_logd macros added along with contexts for user space logd. - Specify above on domain wide, or service-by-service basis - Add logd rules. - deprecate access_logcat as unused. - 'allow <domain> zygote:unix_dgram_socket write;' rule added to deal with fd inheritance. ToDo: investigate means to allow references to close, and reopen in context of application or call setsockcreatecon() to label them in child context.
