(cherry pick from commit 100658c303)
- logpersistd is defined as a thread or process in the context of the
logd domain. Here we define logpersistd as logcat -f in logd domain
and call it logcatd to represent its service mechanics.
- Use logcatd to manage content in /data/misc/logd/ directory.
- Only turn on for persist.logd.logpersistd = logcatd.
- Add logpersist.start, logpersist.stop and logpersist.cat debug
class executables, thus only in the eng and userdebug builds.
ToDo: Wish to add Developer Options menu to turn this feature on or
off, complicated by the fact that user builds have no tools with
access rights to /data/misc/logd.
