(cherry pick from commit c18c2130d0)
- Check if the result of opendir is NULL in lastLogTime
- Cleanup: alphabetically sorted long options, reserved
an alias for --regex
- Add a unit test, non existent directory should return
gracefully with an exit(1) and not SIGSEGV.
NB: This failure was with eng/debug feature logpersist
turned on, /data/misc/logd/ directory was missing,
deleted, or temporarily inaccessible.

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.

- '-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.

Move away from using POSIX open(2) flags and introduce ANDROID_LOG_* flags to
replace them. Add security by preventing random mode flags from getting into
underlying POSIX calls. ANDROID_LOG_* flags overlap POSIX O_* flag definitions.

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.
