1ec3b78b67 libprocessgroup users use libcutils
libprocessgroup symbols are being moved into libcutils in order to
optimize linking/memory usage. libprocessgroup will no longer be
required in the future (however removing references to it will come
separately).

Bug: 135145426
Test: boot

Test:
BEFORE:
$ adb shell showmap -a $(pid hwservicemanager) | grep -P "libprocessgroup|libcutils" -A1 | grep -P 'libprocessgroup|libcutils|\.bss' | awk '{s += $9}END{print s}'

AFTER:
$ adb shell showmap -a $(pid hwservicemanager) | grep -P "libprocessgroup|libcutils" -A1 | grep -P 'libprocessgroup|libcutils|\.bss' | awk '{s += $9}END{print s}'

Siarhei Vishniakou
6606d8df32 Logtags for com.android.server.policy
The definitions for event log tags are currently in system/core. Instead
of keeping them there, reserve a range for these event tags and move
them into com.android.server.policy.

Currently it is only used by PhoneWindowManager.

c6ad69d1d4 liblog: don't return 0xFFFFFFFF as an invalid log id.
There are a bunch of branches that check "id >= LOG_ID_MAX", but because
C++ hates you, this does a promotion to signed int despite the
fact that both sides of the comparison are the same enum with an
underlying type of unsigned int. (C++17 §7.6.3)

Return LOG_ID_MAX instead of a value that gets promoted to signed -1, to
avoid this.

01bdb04be6 liblog: allow event tags to include some punctuations
event_log_tag parser complains about a period (.) in the name,
we would consider such an enhancement to the tag names possible.
I expect we would want to be able to support alphanumerics,
underscore (_), period (.), minus (-), at (@) and comma (,) for
starters as they are present in the other text log buffer tags.

We introduce a local endOfTag function that is used during parsing and
during android_lookupEventTagNum for submitting new tags.  This
function caused us to enforce const char more closely.  By filtering
in both places we resolve an issue that could have plagued us if
garbage requests were made.

5768d3d976 liblog: logprint supports number of seconds time event field
Add s to report time in seconds.  The time could be a period, duration
or monotonic, expanded to seconds, minutes, hours and days.  gTest has
to acquire a dynamic tag allocation as there are no users of this
feature yet.

Looking to the future, audio media logging has binary content similar
to the binary events structures Android logging uses and they have
a definition of a duration field in their internal binary logging, so
may be of use when we unify the logs.

46186a7238 logcat: test: standardize rest() to let logs land when injecting
Add an internal rest() function to set the standard for how long we
should wait for a log message to land end to end into the logs.  Add
a retry on -EBUSY for all descriptive tests along with a rest() after
log injection so the tests can try to survive heavy Denial Of Service
(DOS) loads.  Some of the resting was done at a coarse 1 second, when
200ms will do just fine.

Fix a few pesky issues surrounding test reliability and correctness:
- stdint.h include missing.
- missing a logcat_executable, means logcatd.descriptive testing was
  testing logcat instead.
- count of interfering tests is 3 now: logcat, liblogcat and logcatd, if
  they all run in the same PID, we have to not fail.
- Added a missed opportunity to add uniqueness to logcat.descriptive sync
  test.

a073c39616 logcatd: introduce logcatd executable
logcatd is the same as logcat, except that the -L flag, if supplied,
runs once, then the command re-runs itself without the -L flag with
the same argument set.  By introducing a logcatd daemon executable
we can solve the problem of the longish reads from pstore that
sometimes occur when the system is excessively busy, starving this
background cgroup daemon as we absorb the delay in a backgrounded
init "service", rather than in a forgrounded init "exec".  This would
not have been efficiently possible without the introduction of
liblogcat.

There are no doubt many flags that make no sense to run twice with,
and without, the -L flag.  In the general sense we expect the caller
to perform the correct set of operations and not pick these nonsense
operations.  logcatd is only supplied on engineering and debug builds
for logpersist, and is only an automated aid to triage.

fbc0fe429b logcat: test: run 256 simultaneous logcats
For logd daemon, heavy reader stress. For system popen fork and
execute of logcat measure baseline against liblogcat. For liblogcat
local concurrent thread, locking, argument parsing and context scaling
for popen-style pair of android_logcat_run_command_thread* functions.

NB: 1000 logcat executables ran, but did not scale well on time
    blocked for more than a minute. With 343 contexts of
    android_logcat_run_command_thread ran out of local resources
    to even return a file descriptor, and the per-context event tag
    mappings coincidentally ran out at 340 when threads ran, although
    that path was consistently 15% faster than the popen test.
