Mark Salyzyn 7cc8013e37 liblog: fix android_log_printLogLine empty event string
Allow _one_ empty line to get through before evaluating
further. Add __android_log_bswrite testing for content
and contentless cases; checking for propagation and for
expected printing. As for printing which is fixed here,
security variants cover the same code paths as the events.

Mark Salyzyn d7bcf40ee6 liblog: print message payload of zero length
logcat will crash if the log message payload is of zero length. Side
effect of possible log messages from LogKlog in eng and userdebug
builds, or lower level logging calls.

NB: The referenced bug cited an example of this native crash, this
    does not fix the problem cited in the bug about the
    com.android.music shutdown.

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.

Pierre Zurek ead88fca6e liblog: logcat: colored output.
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.

Colin Cross 9227bd3855 Move liblog headers to system/core/include/log
Move the liblog headers to log/ instead of cutils/ to complete
the separation of libcutils and liblog.  cutils/log.h still
exists and includes log/log.h in order to support the many existing
modules that use cutils/log.h.

Nick Kralevich e1ede1530f liblog: do better checks of log messages.
Testing:

The following test cases all passed and generated log entries:

 # echo -n '\03foo\0bar\0' > /dev/log/main
 # echo -n '\03\0bar\0' > /dev/log/main
 # echo -n '\03\0a\0' > /dev/log/main

The following entries were successfully processed by
logcat but produced no log entries:

 # echo -n '\03\0\0' > /dev/log/main
 # echo -n '\03a\0\0' > /dev/log/main
 # echo -n '\03b\0\0' > /dev/log/main

Also tested the pathological error condition:

 cat /dev/urandom > /dev/log/main

which produced many "+++ LOG: malformed log entry" errors.

snprintf has a weird return value.   It returns what would have been written given a large enough buffer.
In the case that the prefix is longer then our buffer(128), it messes up the calculations below possibly causing heap corruption.
To avoid this we double check and set the length at the maximum (size minus null byte
