if ro.logd.timestamp or persist.logd.timestamp are set to the value
monotonic then liblog writer, liblog printing and logd all switch to
recording/printing monotonic time rather than realtime. If reinit
detects a change for presist.logd.timestamp, correct the older entry
timestamps in place.
ToDo: A corner case condition where new log entries in monotonic time
occur before logd reinit detects persist.logd.timestamp, there
will be a few out-of-order entries, but with accurate
timestamps. This problem does not happen for ro.logd.timestamp
as it is set before logd starts.
NB: This offers a nano second time accuracy on all log entries
that may be more suitable for merging with other system
activities, such as systrace, that also use monotonic time. This
feature is for debugging.

Switch to using string and length in all transactions, treating
trailing nuls the same as spaces.
ToDo: change dumpstate (bugreport) to use logcat -b printable _regardless_

- logDmesg method consumes considerable memory
resources (typically 128KB depending on kernel)
- In the future (eg: klogd, syslogd) there may be need to
feed multiple logs or threads with the retrieved data.
- By moving the actions of logDmesg into the mainline that
instantiates the thread objects, we can leverage a single
allocation of the the kernel log allocation.
- logDmesg (private) is replaced with log (public) which
has a more useful and descriptive purpose for the class.

Initial commit for an audit daemon that writes kernel audit
messages to the Android logger. The daemon searches dmesg
for all lines that contain "audit" and writes them. Then
receiving the messages from the netlink socket.
It also formats the messages so they are compatable with
ausearch (type=<t> <m> format)

- do not start auditd
- merge into logd, stripping unnecessary file logging.
- Convert headers and code to support C++
- Fix bugs in libaudit
- squash timestamp (replace with 0.0) due to duplication
- squash pid due to duplication
- squash comm due to duplication
