- 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.

(cherry pick from commit ae4d928d816e30dbe57c2c321b0f0759d0567b3f)

- Add a klogd to collect the kernel logs and place them into a
  new kernel log buffer
- Parse priority, tag and message from the kernel log messages.
- Turn off pruning for worst UID for the kernel log buffer
- Sniff for 'PM: suspend exit', 'PM: suspend enter' and
  'Suspended for' messages and correct the internal definition
  time correction against monotonic dynamically.
- Discern if we have monotonic or real time (delineation 1980) in
  audit messages.
- perform appropriate math to correct the timestamp to be real time
- filter out any external sources of kernel logging

This forward port reverts
    commit e457b74ce6ee6d799812dc2ec5e4b8b18bcd3e91

No longer as necessary once we add
    liblog: Instrument logging of logd write drops
Although this provided an indication of how close statistically we
were to overloading logd it is simpler to understand fails thus to
hunt and peck a corrected value for /proc/sys/net/unix/max_dgram_qlen
