Mark Salyzyn b6bee33182 liblog: logd: support logd.timestamp = monotonic
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.

Mark Salyzyn 4cbed02e44 liblog: logcat: add epoch and monotonic format modifiers
- '-v epoch' prints seconds since Jan 1 1970
- '-v monotonic' print cpu seconds since start of device
- '-T sssss.mmm...' as alternate tail time format

NB: monotonic is a best estimate and may be out by a few ms
    given the synchronization source clue accuracy.

Riley Andrews aede9897df Lower the priority of the threads in logd/logcat.
(cherry pick from commit d98f4e8af5)

sched_batch implies only a penalty to latency in scheduling, but
does not imply that the process will be given less cpu time. Increase
the nice level to 10 to prioritize it below ui threads.

Traian Schiau 5976303aa6 logcat: Minor fixes
Remove -r default value implementation (since is not functional).
Check the status of some memory allocations.
Make sure that the pruning buffer is set to NULL if we get to the end of  the loop.
Make sure that the file status is successfully retrieved before using the size.
Add strtouia - string to unsigned argument.
Add logcat_panic with/without printing an error message and help.
Play nicer with the android namespace.

This patch adds a new '-v color' option to logcat so that the output is
colored similar to the ones in DDMS. Simply type "adb logcat -v color"
to use it. Works well with bash in gnome-terminal. NO GUARANTEE IT WILL
WORK ON A NON xterm STYLE TERMINAL.
