Mark Salyzyn 831aa29730 logd: worst uid record watermark part four
With part deux we caused an apparent regression by not checking for
stale recorded iterators. This checking was on-purpose bypassesed
when leading prune entries were to be deleted without touching the
statistics engine due to an in-place merge.

Part deux had us leaving iterators we were not focussed on untouched
which in turn because they were left behind, had a much higher
likelihood of being deleted without touching the statistics engine.

Perform the check every delete.

                                         sent on to dmesg log
logd.klogd                  bool depends Enable klogd daemon
logd.statistics             bool depends Enable logcat -S statistics.

                                         default false

                                         turns on logcat -f in logd context
persist.logd.size          number 256K   default size of the buffer for all
                                         log ids at initial startup, at runtime
                                         use: logcat -b all -G <value>

persist.logd.size.crash    number 256K   Size of the buffer for the crash log

NB:
- number support multipliers (K or M) for convenience. Range is limited
  to between 64K and 256M for log buffer sizes. Individual logs override the
  global default.
