a46326a51c logcat: unit test produces log stutter
logd now counts multiple identical messages, causing messages to be
held back.  Stop doing that in the tests.  When that filter appeared,
the logcat-unit-tests went from 23 seconds to a couple of minutes of
runtime breakign the automated testing.

Test: gTest logcat-unit-tests total time less than 1 minute.

1179eb8048 system/core: replace EVENT_TAG_MAP_FILE with NULL
NULL represents system default.  In the future, NULL could represent
static and dynamic tags, which can come from multiple files based on
implementation details in the liblog library.

1a57ae3a7d liblog: logprint: report truncated event log contents if error
We need to accept that a log tag can contain no payload.  For those
that are corrupted, and to aid debugging, report what we did manage
to interpret.  Report last character as a ! for corruption, and ^
for truncation.  Fix a few Android Coding standard issues.

Expand logprint feature to pull out the log tag description
fields, parse them and merge into the logging content.  Add
-v descriptive, -v colour(british, hidden) and -v help. Also
added a unit test for the descriptive format borrowing from
event tags that have been unchanged since 2009.

Had to add -v help because we have too many undocumented
formats and format adverbs.

9f53cac1b4 fix regression from android_lookupEventTag_len()
Commit 807e40ecc9 'liblog: logd: Add
android_lookupEventTag_len()' which addressed a Dirty Shared memory
leak resulted in a regression. Most notably logcat <tag> stopped
working for the events log buffer.

AndroidLogEntry::tag also requires callers to check out
AndroidLogEntry::tagLen as tag is no longer guaranteed to be
nul terminated.

ad5e411608 logcat: -d, -t or -L, along with -f, do not background
Specifically logcatd with exec logcat -L needs to be foreground
process cgroup as it is spawned and can block init progress. Makes
sense generally to only set background cgroup when we are taking
continuous content, and we are pushing that content to a set of
logrotate files.

Rename setupOutput to setupOutputAndSchedulingPolicy to more
clearly indicate its purpose.

31961061d5 logcat: lastLogTime only two most recent files
Scaling issues if -f logrotation is specified and there are a lot of
log files to process in lastLogTime, focus on only the last two log
files. This will cover the situation where we have recently rotated
the logs and the last file is missing or empty.

This also alters monotonic processing as well as it used to focus on
only the last file; the danger being doubled now if the pair covers
more than one reboot when filling in missing content with logcat -L.
Problem was always there with one log file, but now we handle if
rotation happened recently. A fair tradeoff for KISS.

02687e75b0 logcat: add --id=<id> for -f option
Clear file rotate content if id signature changes. This allows
logcatd to detect change of property ro.build.id to reset the
recorded data. The id is stored in the the -f filespec as
<filespec>.id.

If the id file is missing or unreadable, do not clear. Allow an
API where chmod 0 to the id file blocks this feature. Does not
work for root.

Add logcat.logrotate_id gTest.

df5d12850a logcatd: trampoline persist.logd.logpersistd to logd.logpersistd
(cherry pick from 2591d483c8)

Best practices so that device can set logd.logpersistd properties.
Values can be overriden with trampolines for persist.logd.logpersistd
values except as designed for empty content to keep out of the way.

This allows us to set logd.logpersistd* for a non-persistent collection
that does not survive a reboot, and to use persist.logd.logpersistd*
for persistent collection that does survive a reboot.

Added logd.logpersistd.enable to gate when logpersist service can be
run allowing the properties to be adjusted safely prior to this state
as is the case for device property.

NB: /init will complain when trying to trampoline an empty property,
    this is acceptable for functionality, but may be considered
    annoying from the logging perspective.

If -c and -f are both specified, clear the files rather
than notifying the logger to clear its data. The -f then
acts like a switch between clearing the in-memory log
data, or the on-disk logrotate data.

- shell script bloating up to deal with option validation and

- Deprecate shell script and replace with Eng and Userdebug
  only Developer Options, before it becomes too powerful
  or bloated to force us to rewrite an expendable like this
  into C++.
