log/logger.h pieces moved into log/log.h. Correct for some
minor Android Coding standards.

Always used in combination with log/logger.h except in log_time.cpp,
and not used externally. As a result liblog has to support stl, a
small price to pay since goal is to convert liblog to C++ internally.
Test: compile

Skip leading 'c0 32767 ' and place pid (32767 in example) into pid
field of log record.

(cherry pick from commit 2ad0bd0a9b)
LogReader.h needs to be individually importable.
Fix a few others, drop includes of local includes, let them be
included in source instead and allow headers to be included
alphabetically. Was not a complete audit since goal was to
separate LogReader.h out from the pack.

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_

Rename to log_strntok_r and change from dealing with strings
to dealing with a string and an associated length.

- sniff for PID in kernel log messages if available
- properly deal with klogd watermark in face of modified output
- deal more stringently with priority tag, must have [ following
- suppress process-name stutter in tag that can happen
- do not use : to demark tag if within [ ]
Mediatek-special change that adds <printk_state>(<cpu>)[<pid>:<comm>]
as a prefix to the printk messages. Along the lines of (simplified
for entertainment purposes, YMMV):
char tbuf[50]; /* printk prefix */
int this_cpu = smp_processor_id();
char state = __raw_get_cpu_var(printk_state);
unsigned tlen = snprintf(tbuf, sizeof(tbuf), "%c(%x)[%d:%s]",
state, this_cpu, current->pid, current->comm);

- 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 there log messages.

- 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
