- logpersistd is defined as a thread or process in the context of the
logd domain. Here we define logpersistd as logcat -f in logd domain
and call it logcatd to represent its service mechanics.
- Use logcatd to manage content in /data/misc/logd/ directory.
- Only turn on for persist.logd.logpersistd = logcatd.
- Add logpersist.start, logpersist.stop and logpersist.cat debug
class executables, thus only in the eng and userdebug builds.
ToDo: Wish to add Developer Options menu to turn this feature on or
off, complicated by the fact that user builds have no tools with
access rights to /data/misc/logd.

- 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

- internal dropped entries are associated by prune by worst UID
and are applied by UID and by PID
- track dropped entries by rewriting them in place
- merge similar dropped entries together for same UID(implied),
PID and TID so that blame can more clearly be placed
- allow aging of dropped entries by the general backgound pruning
- report individual dropped entries formatted to reader
- add statistics to track dropped entries by UID, the combination
of statistics and dropped logging can track over-the-top Chattiest
clients.

- auditd switch to recording logs to events log id
- logcat add events as one of the default logs
- debuggerd collect events log as well.
ToDo: debuggerd & bugreport collect intermixed logs.

* Test statistics output, all four main log id types
are checked to be present, and output is properly
formatted with header (ascii new-line terminated
byte count) and trailer (newline formfeed) frames.
* On dev build test dgram_qlen, circumvent if
liblog benchmarks executed first though.
* Test if kernel and user space loggers are
present, and if any content has leaked to both.
* test benchmark and use it to verify worst UID pruning

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

- liblog android_logger_get_log_size and android_logger_get_readable_size
adjusted to return long instead of int because of -G flag extending range
NB: ifdef'd only for userdebug and eng builds
- liblog Add android_logger_[sg]et_prune_list and android_logger_set_log_size
- logcat Add -P, -p and -G flags
- logd Add LogWhiteBlackList and configurable log size
