For the gTests logcat.tz, logcat.tail_3, logcat.tail_10,
logcat.tail_100, logcat.tail_1000 and logcat.tail_time tests inject
messages if we come up short should the background logging not be
sufficient to feed the test requirements. Test frames run the
tests right after reboot requiring injection. Will have radio
silence, so we also add kernel logs if available to help add to the
background logging activity level.
We also will inject a radio message for logcat.buckets so that test
can survive no radio content.
Test: set device to airplane mode (to stress this problem) then:
adb logcat -b all -c && adb shell su root \
/data/nativetest/logcat-unit-tests/logcat-unit-tests \
--gtest_filter=logcat.tail_1000 (or others in this set)

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.

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.

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.

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.

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.

Change-Id: Ice0b950040bd05dcd49b7315def4dac3dd93eb27
(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
