Mark Salyzyn df5902c4f3 logd: fix kernel logline stutter
(cherry pick from commit 2c3b300fd8)

- look for cases where one log line contains two without a newline.
- rare condition, occurs when a printk does not have
  a terminating newline under certain race conditions.
- the newline may be performed broken up as a second call
- the timestamps can be reversed (showing the race effects).
- driver(s) should really have the newline in their log messages.

Mark Salyzyn a1aacb71f3 logd: Add klogd
(cherry pick from commit ae4d928d81)

- 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
