6f061e8d64 logcat: modernize the code
1) Use libbase parsing functions instead of our own versions
2) Remove log_device_t, as it's an unneeded wrapper around log buffers
3) Do not report 'unexpected' if we get a log from a buffer that we
   didn't reqest.  I checked and I don't see any references to this
   happening in practice, so the code is mostly superfluous.  It seems
   reasonable enough to report the actual buffer name instead of
   'unexpected' in any case.
4) Print all buffers that experience an error, not just the first one
   seen.

Test: logcat works, logcat-unit-tests

d162f14d6c logcat: remove the rest of liblogcat
There were big changes made to support liblogcat, which has long since
been removed.  This change removes the rest of those changes.

It moves the rest of the global state into a class, particularly for
the logcatd case.  The original code re-uses the same context, but
that doesn't seem right or safe.

Test: logcat works, logcat-unit-tests
Test: logpersist works, including last log cat and log rotation

441054aa1e Remove old logger_entry_v* formats
logger_entry and logger_entry_v2 were used for the kernel logger,
which we have long since deprecated.  logger_entry_v3 is the same as
logger_entry_v4 without a uid field, so it is trivially removable,
especially since we're now always providing uids in log messages.

liblog and logd already get updated in sync with each other, so we
have no reason for backwards compatibility with their format.

Test: build, unit tests

fe535f5e68 logcat: add 'kernel' to defaults
I'm asked at least once a week or more why a new service isn't starting.

00813a585a Logcatd: Add new properties control logcat file size and file count.
Logcatd has capability to output logs to filesystem with certain size
and certain file count, however file size is not configurable, fixed
as 1024 kbytes, file count is configurable, but original property
name didn't match the logcat parameter well.
This patch add interface rotate_kbytes and count into logcatd.rc.
rotate_kbytes used to control each logcat file size.
count is another alias for logd.logpersistd.size to control file number.

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.
